Human Extinction Quotes

We're so self-important. So arrogant. Everybody's going to save something now. Save the trees, save the bees, save the whales, save the snails. And the supreme arrogance? Save the planet! Are these people kidding? Save the planet? We don't even know how to take care of ourselves; we haven't learned how to care for one another. We're gonna save the fuckin' planet? . . . And, by the way, there's nothing wrong with the planet in the first place. The planet is fine. The people are fucked! Compared with the people, the planet is doin' great. It's been here over four billion years . . . The planet isn't goin' anywhere, folks. We are! We're goin' away. Pack your shit, we're goin' away. And we won't leave much of a trace. Thank God for that. Nothing left. Maybe a little Styrofoam. The planet will be here, and we'll be gone. Another failed mutation; another closed-end biological mistake.

In an individual, selfishness uglifies the soul; for the human species, selfishness is extinction.

What makes you think human beings are sentient and aware? There's no evidence for it. Human beings never think for themselves, they find it too uncomfortable. For the most part, members of our species simply repeat what they are told-and become upset if they are exposed to any different view. The characteristic human trait is not awareness but conformity, and the characteristic result is religious warfare. Other animals fight for territory or food; but, uniquely in the animal kingdom, human beings fight for their 'beliefs.' The reason is that beliefs guide behavior which has evolutionary importance among human beings. But at a time when our behavior may well lead us to extinction, I see no reason to assume we have any awareness at all. We are stubborn, self-destructive conformists. Any other view of our species is just a self-congratulatory delusion. Next question.

Why fight the 'natural' (oh, weaselly word!) order of things? Why? Because of this--one fine day, a purely predatory world shall consume itself. In an individual, selfishness uglifies the soul; for the human species, selfishness is extinction.

A sign in the Hall of Biodiversity offers a quote from the Stanford ecologist Paul Ehrlich: IN PUSHING OTHER SPECIES TO EXTINCTION, HUMANITY IS BUSY SAWING OFF THE LIMB ON WHICH IT PERCHES.

I think human consciousness is a tragic misstep in human evolution. We became too self aware; nature created an aspect of nature separate from itself. We are creatures that should not exist by natural law. We are things that labor under the illusion of having a self, a secretion of sensory experience and feeling, programmed with total assurance that we are each somebody, when in fact everybody’s nobody. I think the honorable thing for our species to do is deny our programming, stop reproducing, walk hand in hand into extinction, one last midnight, brothers and sisters opting out of a raw deal.

People whose history and future were threatened each day by extinction considered that it was only by divine intervention that they were able to live at all. I find it interesting that the meanest life, the poorest existence, is attributed to God's will, but as human beings become more affluent, as their living standard and style begin to ascend the material scale, God descends the scale of responsibility at a commensurate speed.

All the labor of all the ages, all the devotion, all the inspiration, all the noonday brightness of human genius are destined to extinction. So now, my friends, if that is true, and it is true, what is the point?

So of course in the midst of everything, the state of the world being what it is, humanity on the cusp of extinction, here I am writing another email about sex and friendship. What else is there to live for?

Somewhere in our DNA must lie the key mutation (or, more probably, mutations) that set us apart—the mutations that make us the sort of creature that could wipe out its nearest relative, then dig up its bones and reassemble its genome.

We tell our children they're trapped like rats on a doomed, bankrupt, gangster-haunted planet with dwindling resources, with nothing to look forward to but rising sea levels and imminent mass extinctions, then raise a disapproving eyebrow when, in response, they dress in black, cut themselves with razors, starve themselves, gorge themselves, or kill one another.

Some humans theorize that intelligent species go extinct before they can expand into outer space. If they're correct, then the hush of the night sky is the silence of the graveyard.

...supernatural explanations always mean the end of inquiry: that’s the way God wants it, end of story. Science, on the other hand, is never satisfied: our studies of the universe will continue until humans go extinct.

Every human generation has its own illusions with regard to civilization; some believe they are taking part in its upsurge, others that they are witnesses of its extinction. In fact, it always both flames and smolders and is extinguished, according to the place and the angle of view.

Long after the traces of the human animal have disappeared, many of the species it is bent on destroying will still be around, along with others that have yet to spring up. The Earth will forget mankind. The play of life will go on.

The hardest part about working with aliens and saving humanity from extinction is constantly having to come up with names for stuff.

Who in the world has not yearned for a loved one, has never said, If only he or she could come back just once, just one more time...? Despite the fact that it can never happen, never ever. Surely this is the saddest thing about our mortal world, and its sadness will go on shrouding human life like a blanket of fog until its final extinction.

Humanity is not without answers or solutions regarding how to liberate itself from scenarios that invariably end with mass exterminations. Tools such as compassion, trust, empathy, love, and ethical discernment are already in our possession. The next sensible step would be to use them.

By burning through coal and oil deposits, humans are putting carbon back into the air that has been sequestered for tens—in most cases hundreds—of millions of years. In the process, we are running geologic history not only in reverse but at warp speed.

Do not avert your eyes. It is important that you see this. It is important that you feel this.

If humans one day become extinct from a catastrophic collision, there would be no greater tragedy in the history of life in the universe. Not because we lacked the brain power to protect ourselves but because we lacked the foresight. The dominant species that replaces us in post-apocalyptic Earth just might wonder, as they gaze upon our mounted skeletons in their natural history museums, why large-headed Homo sapiens fared no better than the proverbially pea-brained dinosaurs.

One saw a bird dying, shot by a man. It was flying with rhythmic beat and beautifully, with such freedom and lack of fear. And the gun shattered it; it fell to the earth and all the life had gone out of it. A dog fetched it, and the man collected other dead birds. He was chattering with his friend and seemed so utterly indifferent. All that he was concerned with was bringing down so many birds, and it was over as far as he was concerned. They are killing all over the world. Those marvellous, great animals of the sea, the whales, are killed by the million, and the tiger and so many other animals are now becoming endangered species. Man is the only animal that is to be dreaded.

That Man is the product of causes which had no prevision of the end they were achieving; that his origin, his growth, his hopes and fears, his loves and his beliefs, are but the outcome of accidental collocations of atoms; that no fire, no heroism, no intensity of thought and feeling, can preserve an individual life beyond the grave; that all the labours of the ages, all the devotion, all the inspiration, all the noonday brightness of human genius, are destined to extinction in the vast death of the solar system, and that the whole temple of Man’s achievement must inevitably be buried beneath the débris of a universe in ruins—all these things, if not quite beyond dispute, are yet so nearly certain, that no philosophy which rejects them can hope to stand. Only within the scaffolding of these truths, only on the firm foundation of unyielding despair, can the soul’s habitation henceforth be safely built.

Mankind must destroy anti-humanity before it becomes extinct itself.

We should always be clear that animal exploitation is wrong because it involves speciesism. And speciesism is wrong because, like racism, sexism, homophobia, anti-semitism, classism, and all other forms of human discrimination, speciesism involves violence inflicted on members of the moral community where that infliction of violence cannot be morally justified. But that means that those of us who oppose speciesism necessarily oppose discrimination against humans. It makes no sense to say that speciesism is wrong because it is like racism (or any other form of discrimination) but that we do not have a position about racism. We do. We should be opposed to it and we should always be clear about that.

There's no continuity and the world I have come from is utterly foreign to me. I haven't heard its music, I haven't seen its painting, I haven't read its books... I know only the stony plain, wandering, and the gradual loss of hope. I am the sterile offspring of a race about which I know nothing, not even whether it has become extinct. Perhaps, somewhere, humanity is flourishing under the stars, unaware that a daughter of its blood is ending her days in silence. There is nothing we can do about it.

We are the intelligent elite among animal life on earth and whatever our mistakes, [Earth] needs us. This may seem an odd statement after all that I have said about the way 20th century humans became almost a planetary disease organism. But it has taken [Earth] 2.5 billion years to evolve an animal that can think and communicate its thoughts. If we become extinct she has little chance of evolving another.

We probably didn't know what we were doing thousands of years ago as we hunted some large mammals to extinction. But we know what we're doing now. We know how to tread more lightly upon the earth. We could choose to use less energy, eat less meat, clear fewer forests. And we chose not to. As a result, for many forms of life, humanity is the apocalypse.

Buddhism: a violent religion that has compensated for the exploding human population by causing whole species of animal vessels to go extinct.

Man steps on an ant when he can't catch the fly.

If you want to save the planet, then stop reproducing and allow humanity to go extinct. Let the animals inherit the Earth, we're not worthy.

I love museums more than any other institution the human race has invented. Museum people are always overworked and underpaid, and they all deserve sainthood, every one.

There are so many things to be scared of in this world: blooms of jellies. A sixth extinction. A middle school dance. But maybe we can stop feeling so afraid. Maybe instead of feeling like a mote of dust, we can remember that all the creatures on this Earth are made from stardust. And we are the only ones who get to know it. That's the thing about jellyfish: They'll never understand that. All they can do is drift along, unaware. Humans may be newcomers to this planet. We may be plenty fragile. But we're also the only ones who can decide to change.

Man wants to see nature and evolution as separate from human activities. There is a natural world, and there is man. But man also belongs to the natural world. If he is a ferocious predator, that too is part of evolution. If cod and haddock and other species cannot survive because man kills them, something more adaptable will take their place. Nature, the ultimate pragmatist, doggedly searches for something that works. But as the cockroach demonstrates, what works best in nature does not always appeal to us.

Naturally, society has an indisputable right to protect itself against arrant subjectivisms, but, in so far as society is itself composed of de-individualized human beings, it is completely at the mercy of ruthless individualists. Let it band together into groups and organizations as much as it likes – it is just this banding together and the resultant extinction of the individual personality that makes it succumb so readily to a dictator. A million zeros joined together do not, unfortunately, add up to one. Ultimately everything depends on the quality of the individual, but our fatally short-sighted age thinks only in terms of large numbers and mass organizations, though one would think that the world had seen more than enough of what a well-disciplined mob can do in the hand of a single madman.

The anthropologist Richard Leakey has warned that “Homo sapiens might not only be the agent of the sixth extinction, but also risks being one of its victims.” A sign in the Hall of Biodiversity offers a quote from the Stanford ecologist Paul Ehrlich: IN PUSHING OTHER SPECIES TO EXTINCTION, HUMANITY IS BUSY SAWING OFF THE LIMB ON WHICH IT PERCHES.

science devises ever bloodier means of war until humanity’s powers of destruction overcome our powers of creation and our civilisation drives itself to extinction.

Every day on this planet some species that doesn't draw the attention of humans goes extinct.

with the exception of humans, all the great apes today are facing oblivion.

Were the Australian extinction an isolated event, we could grant humans the benefit of the doubt. But the historical record makes Homo sapiens look like an ecological serial killer.

We are killing off species at the rate of about one per day. It is estimated that humans are driving species to extinction at least a thousand times faster than the otherwise natural rate.

We are the hands and eyes and ears, the sensitive probing feelers through which the emergent, intelligent universe comes to know its own form and purpose. We bring the thunderbolt of meaning and significance to unconscious matter, blank paper, the night sky. We are already divine magicians, already supergods. Why shouldn't we use all our brilliance to leap in as many single bounds as it takes to a world beyond ours, threatened by overpopulation, mass species extinction, environmental degradation, hunger, and exploitation? Superman and his pals would figure a way out of any stupid cul-de-sac we could find ourselves in - and we made Superman, after all. All it takes is that one magic word.

Your cynicism lies in your willing abuse of others to consolidate your superiority over them. My cynicism is in regard to humanity’s wilful blindness with respect to its own extinction.’ ‘Without that wilful blindness there is naught but despair.’ ‘Oh, I am not that cynical. In fact, I do not agree at all. Maybe when the wilful blindness runs its inevitable course, there will be born wilful wisdom, the revelation of seeing things as they are.’ ‘Things? To which things are you referring, old man?’ ‘Why, that everything of true value is, in fact, free.

Dr. Albert Frock: Well, how goes the gradual extinction of the human race, Lieutenant? Lt. Vincent D'Agosta: I'm doing what I can to keep it orderly.

The many sorrows of our recent history suggest that we humans have a learning disability.

If there is danger in the human trajectory, it is not so much in the survival of our own species as in the fulfillment of the ultimate irony of organic evolution: that in the instant of achieving self-understanding through the mind of man, life has doomed its most beautiful creations.

Atheists are the most honest of the human race. These people are unable to live a double life; they are unable to lie to themselves. Of course it's an evolutionary handicap, and if that handicap was widespread, our species would run the risk of extinction

Nature proceeds by blunders; that is its way. It is also ours. So if we have blundered by regarding consciousness as a blunder, why make a fuss over it? Our self-removal from this planet would still be a magnificent move, a feat so luminous it would bedim the sun. What do we have to lose? No evil would attend our departure from this world, and the many evils we have known would go extinct along with us. So why put off what would be the most laudable masterstroke of our existence, and the only one?

Human race spoilers: we go extinct and none of this shit matters at all. So just enjoy yourself.

Scholars discern motions in history & formulate these motions into rules that govern the rises & falls of civilizations. My belief runs contrary, however. To wit: history admits no rules; only outcomes. What precipitates outcomes? Vicious acts & virtuous acts. What precipitates acts? Belief. Belief is both prize & battlefield, within the mind & in the mind’s mirror, the world. If we believe humanity is a ladder of tribes, a colosseum of confrontation, exploitation & bestiality, such a humanity is surely brought into being, & history's Horroxes, Boerhaaves & Gooses shall prevail. You & I, the moneyed, the privileged, the fortunate, shall not fare so badly in this world, provided our luck holds. What of it if our consciences itch? Why undermine the dominance of our race, our gunships, our heritage & our legacy? Why fight the “natural” (oh, weaselly word!) order of things? Why? Because of this:—one fine day, a purely predatory world shall consume itself. Yes, the devil shall take the hindmost until the foremost is the hindmost. In an individual, selfishness uglifies the soul. For the human species, selfishness is extinction. Is this the doom written within our nature? If we believe that humanity may transcend tooth & claw, if we believe divers races & creeds can share this world as peaceably as the orphans share their candlenut tree, if we believe that leaders must be just, violence muzzled, power accountable & the riches of the Earth & its Oceans shared equitably, such a world will come to pass. I am not deceived. It is the hardest of worlds to make real. Torturous advances won over generations can be lost by a single stroke of a myopic president’s pen or a vainglorious general’s sword. A life spent shaping a world I want Jackson to inherit, not one I fear Jackson shall inherit, this strikes me as a life worth the living.

one fine day, a purely predatory world shall consume itself. Yes, the Devil shall take the hindmost until the foremost is the hindmost. In an individual, selfishness uglifies the soul; for the human species, selfishness is extinction

Anyone who truly wants to escape human solipsism should not seek out empty places. Instead of fleeing to desert, where they will be thrown back into their own thoughts, they will d better to seek out the company of other animals. A zoo is a better window from which to look out of the human world than a monastery.

A "matriarchal world" does not mean matrilineal or that one queen shall rule the world. It simply means "a world in which a Mother's Heart leads all social institutions, corporations, and governments." All humans-men, women, or transgender-can embody a mother's heart if they so choose. We are destined for extinction as a human race unless a mother's heart assumes leadership of the world.

The separation of man from nature, man placing himself over and above it, is directly responsible for the current ecological situation which may lead to the extinction of many forms of life, including human life. Man has treated nature much as he has treated woman: with rape, plunder, violence.

Few problems are less recognized, but more important than, the accelerating disappearance of the earth's biological resources. In pushing other species to extinction, humanity is busy sawing off the limb on which it is perched.

Humanity can no longer stand by in silence while our wildlife are being used, abused and exploited. It is time we all stand together, to be the voice of the voiceless before it's too late. Extinction means forever.

The beauty of this world where almost everyone was gone. If hell is other people, what is a world with almost no people in it? Perhaps soon humanity would simply flicker out, but Kirsten found this thought more peaceful than sad. So many species had appeared and later vanished from this earth; what was one more? How many people were even left now?

For all the environmental troubles single-use shopping bags cause, the much greater impacts are in what they contain. reducing the human footprint means addressing fundamentally unsustainable habits of food consumption, such as expecting strawberries in the depths of winter or buying of seafood that are being fished to the brink of extinction.

having freed ourselves from the constraints of evolution, humans nevertheless remain dependent on the earth’s biological and geochemical systems. By disrupting these systems—cutting down tropical rainforests, altering the composition of the atmosphere, acidifying the oceans—we’re putting our own survival in danger.

In a sense, the Earth is mounting an immune response against the human species. It is beginning to react to the human parasite, the flooding infection of people, the dead spots of the concrete all over the planet, the cancerous rot-outs in Europe, Japan and the United States, thick with replicating primates, the colonies enlarging and spreading and threatening to shock the biosphere with mass extinctions. Perhaps the biosphere does not 'like' the idea of five billion humans.

I only know the stony plain, wandering, and the gradual loss of hope. I am the sterile offspring of a race about which I know nothing, not even whether it has become extinct. Perhaps, somewhere humanity is flourishing under the stars, unaware that a daughter of its blood is ending her days in silence. There is nothing we can do about it.

We are rendering many species extinct; we may even succeed in destroying ourselves. But this is nothing new for the Earth. Humans would then be just the latest in a long sequence of upstart species that arrive on-stage, make some alterations in the scenery, kill off some of the cast, and then themselves exit stage-left forever. New players appear in the next act. The Earth abides. It has seen all this before.

The strain of constant adaptation to so many fearful events and discoveries is already too much to bear with sanity; one has to keep pretending to slip successfully into the new mould; a time will come when the tailored and camouflaged mind breaks beneath the burden; the stick insect in our brains no longer cares to resemble a twig on the same habitual human tree in the mere hope that it may survive extinction.

Other animals fight for territory or food; but, uniquely in the animal kingdom, human beings fight for their ‘beliefs.’ The reason is that beliefs guide behavior, which has evolutionary importance among human beings. But at a time when our behavior may well lead us to extinction, I see no reason to assume we have any awareness at all. We are stubborn, self-destructive conformists. Any other view of our species is just a self-congratulatory delusion.

I am opposed to animal welfare campaigns for two reasons. First, if animal use cannot be morally justified, then we ought to be clear about that, and advocate for no use. Although rape and child molestation are ubiquitous, we do not have campaigns for “humane” rape or “humane” child molestation. We condemn it all. We should do the same with respect to animal exploitation. Second, animal welfare reform does not provide significant protection for animal interests. Animals are chattel property; they are economic commodities. Given this status and the reality of markets, the level of protection provided by animal welfare will generally be limited to what promotes efficient exploitation. That is, we will protect animal interests to the extent that it provides an economic benefit.

He caught a glimpse of that extraordinary faculty in man, that strange, altruistic, rare, and obstinate decency which will make writers or scientists maintain their truths at the risk of death. Eppur si muove, Galileo was to say; it moves all the same. They were to be in a position to burn him if he would go on with it, with his preposterous nonsense about the earth moving round the sun, but he was to continue with the sublime assertion because there was something which he valued more than himself. The Truth. To recognize and to acknowledge What Is. That was the thing which man could do, which his English could do, his beloved, his sleeping, his now defenceless English. They might be stupid, ferocious, unpolitical, almost hopeless. But here and there, oh so seldome, oh so rare, oh so glorious, there were those all the same who would face the rack, the executioner, and even utter extinction, in the cause of something greater than themselves. Truth, that strange thing, the jest of Pilate's. Many stupid young men had thought they were dying for it, and many would continue to die for it, perhaps for a thousand years. They did not have to be right about their truth, as Galileo was to be. It was enough that they, the few and martyred, should establish a greatness, a thing above the sum of all they ignorantly had.

Perhaps the records will never be intercepted. Perhaps no one in five billion years will ever come upon them. Five billion years is a long time. In five billion years, all human beings will have become extinct or evolved into other beings, none of our artifacts will have survived on Earth, the continents will have become unrecognizably altered or destroyed, and the evolution of the Sun will have burned the Earth to a crisp or reduced it to a whirl of atoms. Far from home, untouched by these remote events, the Voyagers, bearing the memories of a world that is no more, will fly on.

In fact, the American Mastodon vanished around thirteen thousand years ago. Its demise was part of a wave of disappearances that has come to be known as the megafauna extinction. This wave coincided with the spread of modern humans and, increasingly, is understood to have been a result of it. In this sense, the crisis Cuvier discerned just beyond the edge of recorded history was us.

As the ego-dead, so we might imagine, we would continue to know pain in its various forms—that is the essence of existence—but we would not be cozened by our egos to take it personally, an attitude that converts an individual’s pain into conscious suffering. Naturally, we would still have to feed, but we would not be omnivorous gourmands who eat for amusement, gorging down everything in nature and turning to the laboratory for more. As for reproduction, who can say? Animals are driven to copulate, and even as the ego-dead we would not be severed from biology, although we would not be unintelligently ruled by it, as we are now. As a corollary of not being unintelligently ruled by biology, neither would we sulk over our extinction, as we do now. Why raise another generation destined to climb aboard the evolution treadmill? But then, why not raise another generation of the ego-dead? For those who do not perceive either their pleasures or their pains as belonging to them, neither life nor death would be objectionable or not objectionable, desirable or not desirable, all right or not all right. We would be the ego-dead, the self-less, and, dare we are, the enlightened.

Because the egoic mind has led us to feel separate from our immortal Ground of Being over the millennia, we have invented a number of immortality symbols to give us a precarious sense of security and identity in life. Traditionally, these have been religious in character, such as the belief in everlasting life after death, in the West, and the belief in reincarnation, in the East. However, today, it is money that provides the primary immortality symbol. It is our obsession for money that is driving humanity to extinction. For when we do not face our fears with full consciousness and intelligence, these fears will eventually come along to haunt us.

The most effective alternative process [to punishment] is probably extinction. This takes time but is much more rapid than allowing the response to be forgotten. The technique seems to be relatively free of objectionable by-products. We recommend it, for example when we suggest that a parent 'pay no attention' to objectionable behavior on the part of his child. If the child's behavior is strong only because it has been reinforced by 'getting a rise out of' the parent, it will disappear when this consequence is no longer forthcoming. (p. 192)

The living dead had taken more from us than land and loved ones. They'd robbed us of our confidence as the planet's dominant life form. We were a shaken, broken species, driven to the edge of extinction and grateful only for tomorrow with perhaps a little less suffering than today. Was this the legacy we would leave our children, a level of anxiety and self-doubt not seen since our simian ancestors cowered in the tallest trees? What kind of world would they rebuild? Would they rebuild at all? Could they continue to progress, knowing that they would be powerless to reclaim their future? And what if that future saw another rise of the living dead? Would our descendants rise to meet them in battle, or simply crumple in meek surrender and accept what they believe to be their inevitable extinction? For this alone, we had to reclaim our planet. We had to prove to ourselves that we could do it, and leave that proof as this war's greatest monument. The long, hard road back to humanity, or the regressive ennui of Earth's once-proud primates. That was the choice, and it had to be made now.

Human activity has brought my kind to the brink of extinction, but I don’t blame them for it. They didn’t do it maliciously. They just weren’t paying attention. And humans create such beautiful myths; what imaginations they have. Perhaps that’s why their aspirations are so immense. Look at Arecibo. Any species who can build such a thing must have greatness within them. My species probably won’t be here for much longer; it’s likely that we’ll die before our time and join the Great Silence. But before we go, we are sending a message to humanity. We just hope the telescope at Arecibo will enable them to hear it. The message is this: You be good. I love you.

My father then said, ‘Mike, I’ve told you how dinosaurs went extinct. An asteroid crashed into the Earth. The world first became a sea of fire, and then sank into a prolonged period of darkness and coldness.… One night, you woke from a nightmare, saying that you had dreamt that you were back in that terrifying age. Let me tell you now what I wanted to tell you that night: If you really lived during the Cretaceous Period, you’d be fortunate. The period we live in now is far more frightening. Right now, species on Earth are going extinct far faster than during the late Cretaceous. Now is truly the age of mass extinctions! So, my child, what you’re seeing is nothing. This is only an insignificant episode in a much vaster process. We can have no sea birds, but we can’t be without oil. Can you imagine life without oil? Your last birthday, I gave you that lovely Ferrari and promised you that you could drive it after you turned fifteen. But without oil, it would be a pile of junk metal and you’d never drive it. Right now, if you want to visit your grandfather, you can get there on my personal jet and cross the ocean in a dozen hours or so. But without oil, you’d have to tumble in a sailboat for more than a month.… These are the rules of the game of civilization: The first priority is to guarantee the existence of the human race and their comfortable life. Everything else is secondary.

I mention all this to make the point that if you were designing an organism to look after life in our lonely cosmos, to monitor where it is going and keep a record of where it has been, you wouldn't choose human beings for the job. But here's an extremely salient point: we have been chosen, by fate or Providence or whatever you wish to call it. It's an unnerving thought that we may be living the universe's supreme achievement and its worst nightmare simultaneously. Because we are so remarkably careless about looking after things, both when alive and when not, we have no idea-- really none at all-- about how many things have died off permanently, or may soon, or may never, and what role we have played in any part of the process. In 1979, in the book The Sinking Ark, the author Norman Myers suggested that human activities were causing about two extinctions a week on the planet. By the early 1990s he had raised the figure to about some six hundred per week. (That's extinctions of all types-- plants, insects, and so on as well as animals.) Others have put the figure ever higher-- to well over a thousand a week. A United Nations report of 1995, on the other hand, put the total number of known extinctions in the last four hundred years at slightly under 500 for animals and slightly over 650 for plants-- while allowing that this was "almost certainly an underestimate," particularly with regard to tropical species. A few interpreters think most extinction figures are grossly inflated. The fact is, we don't know. Don't have any idea. We don't know when we started doing many of the things we've done. We don't know what we are doing right now or how our present actions will affect the future. What we do know is that there is only one planet to do it on, and only one species of being capable of making a considered difference. Edward O. Wilson expressed it with unimprovable brevity in The Diversity of Life: "One planet, one experiment." If this book has a lesson, it is that we are awfully lucky to be here-- and by "we" i mean every living thing. To attain any kind of life in this universe of ours appears to be quite an achievement. As humans we are doubly lucky, of course: We enjoy not only the privilege of existence but also the singular ability to appreciate it and even, in a multitude of ways, to make it better. It is a talent we have only barely begun to grasp. We have arrived at this position of eminence in a stunningly short time. Behaviorally modern human beings-- that is, people who can speak and make art and organize complex activities-- have existed for only about 0.0001 percent of Earth's history. But surviving for even that little while has required a nearly endless string of good fortune. We really are at the beginning of it all. The trick, of course, is to make sure we never find the end. And that, almost certainly, will require a good deal more than lucky breaks.

Two and a half million years ago, when our distant relative Homo habilis was foraging for food across the Tanzanian savannah, a beam of light left the Andromeda Galaxy and began its journey across the Universe. As that light beam raced across space at the speed of light, generations of pre-humans and humans lived and died; whole species evolved and became extinct, until one member of that unbroken lineage, me, happened to gaze up into the sky below the constellation we call Cassiopeia and focus that beam of light onto his retina. A two-and-a-half-billion-year journey ends by creating an electrical impulse in a nerve fibre, triggering a cascade of wonder in a complex organ called the human brain that didn’t exist anywhere in the Universe when the journey began.

Our self-awareness impresses itself on us so cogently, as individuals and as a species, that we cannot imagine ourselves out of existence, even though for hundreds of millions of years humans played no part in the flow of life on the planet. When Teilhard de Chardin wrote, "The phenomenon of Man was essentially foreordained from the beginning," he was speaking from the depth of individual experience, which we all share, as much as from religious philosophy. Our inability to imagine a world without Homo sapiens has a profound impact on our view of ourselves; it becomes seductively easy to imagine that our evolution was inevitable. And inevitability gives meaning to life, because there is a deep security in believing that the way things are is the way they were meant to be.

It is worse, much worse, than you think. The slowness of climate change is a fairy tale, perhaps as pernicious as the one that says it isn’t happening at all, and comes to us bundled with several others in an anthology of comforting delusions: that global warming is an Arctic saga, unfolding remotely; that it is strictly a matter of sea level and coastlines, not an enveloping crisis sparing no place and leaving no life undeformed; that it is a crisis of the “natural” world, not the human one; that those two are distinct, and that we live today somehow outside or beyond or at the very least defended against nature, not inescapably within and literally overwhelmed by it; that wealth can be a shield against the ravages of warming; that the burning of fossil fuels is the price of continued economic growth; that growth, and the technology it produces, will allow us to engineer our way out of environmental disaster; that there is any analogue to the scale or scope of this threat, in the long span of human history, that might give us confidence in staring it down. None of this is true. But let’s begin with the speed of change. The earth has experienced five mass extinctions before the one we are living through now, each so complete a wiping of the fossil record that it functioned as an evolutionary reset, the planet’s phylogenetic tree first expanding, then collapsing, at intervals, like a lung: 86 percent of all species dead, 450 million years ago; 70 million years later, 75 percent; 125 million years later, 96 percent; 50 million years later, 80 percent; 135 million years after that, 75 percent again. Unless you are a teenager, you probably read in your high school textbooks that these extinctions were the result of asteroids. In fact, all but the one that killed the dinosaurs involved climate change produced by greenhouse gas. The most notorious was 250 million years ago; it began when carbon dioxide warmed the planet by five degrees Celsius, accelerated when that warming triggered the release of methane, another greenhouse gas, and ended with all but a sliver of life on Earth dead. We are currently adding carbon to the atmosphere at a considerably faster rate; by most estimates, at least ten times faster. The rate is one hundred times faster than at any point in human history before the beginning of industrialization. And there is already, right now, fully a third more carbon in the atmosphere than at any point in the last 800,000 years—perhaps in as long as 15 million years. There were no humans then. The oceans were more than a hundred feet higher.

Men have nothing in common with me--there is no point of contact; they have foolish little feelings and foolish little vanities and impertinences and ambitions; their foolish little life is but a laugh, a sigh, and extinction; and they have no sense. Only the Moral Sense. I will show you what I mean. Here is a red spider, not so big as a pin's head. Can you imagine an elephant being interested in him-- caring whether he is happy or isn't, or whether he is wealthy or poor, whether his sweetheart returns his love or not, whether his mother is sick or well, whether he is looked up to in society or not, whether his enemies will smite him or his friends desert him, whether his hopes will suffer blight or his political ambitions fail, whether he shall die in the bosom of his family or neglected and despised in a foreign land? These things can never be important to the elephant; they are nothing to him; he cannot shrink his sympathies to the microscopic size of them. Man is to me as the red spider is to the elephant. The elephant has nothing against the spider--he cannot get down to that remote level; I have nothing against man. The elephant is indifferent; I am indifferent.

Thank you for inviting me here today " I said my voice sounding nothing like me. "I'm here to testify about things I've seen and experienced myself. I'm here because the human race has become more powerful than ever. We've gone to the moon. Our crops resist diseases and pests. We can stop and restart a human heart. And we've harvested vast amounts of energy for everything from night-lights to enormous super-jets. We've even created new kinds of people, like me. "But everything mankind" - I frowned - "personkind has accomplished has had a price. One that we're all gonna have to pay." I heard coughing and shifting in the audience. I looked down at my notes and all the little black words blurred together on the page. I just could not get through this. I put the speech down picked up the microphone and came out from behind the podium. "Look " I said. "There's a lot of official stuff I could quote and put up on the screen with PowerPoint. But what you need to know what the world needs to know is that we're really destroying the earth in a bigger and more catastrophic was than anyone has ever imagined. "I mean I've seen a lot of the world the only world we have. There are so many awesome beautiful tings in it. Waterfalls and mountains thermal pools surrounded by sand like white sugar. Field and field of wildflowers. Places where the ocean crashes up against a mountainside like it's done for hundreds of thousands of years. "I've also seen concrete cities with hardly any green. And rivers whose pretty rainbow surfaces came from an oil leak upstream. Animals are becoming extinct right now in my lifetime. Just recently I went through one of the worst hurricanes ever recorded. It was a whole lot worse because of huge worldwide climatic changes caused by... us. We the people." ....

Winston: I don't know - I don't care. Somehow you will fail. Something will defeat you. Life will defeat you. O'Brian: We control life, Winston, at all its levels. You are imagining that there is something called human nature which will be outraged by what we do and will turn against us. But we create human nature. Men are infinitely malleable. Or perhaps you have returned to your old idea that the proletarians or the slaves will arise and overthrow us. Put it out of your mind. They are helpless, like the animals. Humanity is the Party. The others are outside - irrelevant. Winston: I don't care. In the end they will beat you. Sooner or later they will see you for what you are, and then they will tear you to pieces. O'Brian: Do you see any evidence that this is happening? Or any reason why it should? Winston: No. I believe it. I know that you will fail. There is something in the universe - I don't know, some spirit, some principle - that you will never overcome. O'Brian: Do you believe in God, Winston? Winston: No. O'Brian: Then what is it, this principle that will defeat us? Winston: I don't know. The spirit of Man. O'Brian: And do you consider yourself a man? Winston: Yes. O'Brian: If you are a man, Winston, you are the last man. Your kind is extinct; we are the inheritors. Do you understand that you are alone? You are outside history, you are non-existent. His manner changed and he said more harshly: "'And you consider yourself morally superior to us, with our lies and our cruelty?'" Winston: Yes, I consider myself superior. "'...You are the last man,' said O'Brien. 'You are the guardian of the human spirit...

Dickens has not seen it all. The wretched of the earth do not decide to become extinct, they resolve, on the contrary, to multiply: life is their only weapon against life, life is all that they have. This is why the dispossessed and starving will never be convinced (though some may be coerced) by the population-control programs of the civilized. I have watched the dispossessed and starving laboring in the fields which others own, with their transistor radios at their ear, all day long: so they learn, for example, along with equally weighty matters, that the pope, one of the heads of the civilized world, forbids to the civilized that abortion which is being, literally, forced on them, the wretched. The civilized have created the wretched, quite coldly and deliberately, and do not intend to change the status quo; are responsible for their slaughter and enslavement; rain down bombs on defenseless children whenever and wherever they decide that their ‘vital interests’ are menaced, and think nothing of torturing a man to death: these people are not to be taken seriously when they speak of the ‘sanctity’ of human life, or the ‘conscience’ of the civilized world. There is a ‘sanctity’ involved with bringing a child into this world: it is better than bombing one out of it. Dreadful indeed it is to see a starving child, but the answer to that is not to prevent the child’s arrival but to restructure the world so that the child can live in it: so that the ‘vital interest’ of the world becomes nothing less than the life of the child. However—I could not have said any of this then, nor is so absurd a notion about to engulf the world now. But we were all starving children, after all, and none of our fathers, even at their most embittered and enraged, had ever suggested that we ‘die out.’ It was not we who were supposed to die out: this was, of all notions, the most forbidden, and we learned this from the cradle. Every trial, every beating, every drop of blood, every tear, were meant to be used by us for a day that was coming—for a day that was certainly coming, absolutely certainly, certainly coming: not for us, perhaps, but for our children. The children of the despised and rejected are menaced from the moment they stir in the womb, and are therefore sacred in a way that the children of the saved are not. And the children know it, which is how they manage to raise their children, and why they will not be persuaded—by their children’s murderers, after all—to cease having children.

If our shallow, self-critical culture sometimes seems to lack a sense of the numinous or spiritual it’s only in the same way a fish lacks a sense of the ocean. Because the numinous is everywhere, we need to be reminded of it. We live among wonders. Superhuman cyborgs, we plug into cell phones connecting us to one another and to a constantly updated planetary database, an exo-memory that allows us to fit our complete cultural archive into a jacket pocket. We have camera eyes that speed up, slow down, and even reverse the flow of time, allowing us to see what no one prior to the twentieth century had ever seen — the thermodynamic miracle of broken shards and a puddle gathering themselves up from the floor to assemble a half-full wineglass. We are the hands and eyes and ears, the sensitive probing feelers through which the emergent, intelligent universe comes to know its own form and purpose. We bring the thunderbolt of meaning and significance to unconscious matter, blank paper, the night sky. We are already divine magicians, already supergods. Why shouldn’t we use all our brilliance to leap in as many single bounds as it takes to a world beyond ours, threatened by overpopulation, mass species extinction, environmental degradation, hunger, and exploitation? Superman and his pals would figure a way out of any stupid cul-de-sac we could find ourselves in — and we made Superman, after all.

We’re going to discuss only four or five different problems the Earth has, though there are multiple different scenarios going on. If any one of these scenarios were to break down, all life on the planet would eventually die. And at the moment, they’re all about to break down — it’s just a matter of which one breaks down first. And whenever one system goes, then all the rest of them will go eventually, and that’s it, there won’t be any more human life. It will be over with, and we’ll end up just like Mars or the dinosaurs. A few years ago, around the turn of this century, there were thirty million species of life forms on Earth — thirty million different species of life. In 1993 there were about fifteen million. It took billions of years to create these life forms, and in less than a blink of an eye, a mere hundred years, half of the life on this dear Earth is dead. Around thirty species a minute are now becoming extinct somewhere. If you were to watch this planet from space, it would appear to be dying very, very rapidly. Yet we’re going on as though nothing’s happening and everything’s great. We’re sticking money in the bank and driving our cars and just wiggling right on. Yet from an honest point of view, we have a real life-and-death problem going on here on Earth, and few people seem to be really serious about it.

On the other hand it is possible that human control over the machines may be retained. In that case the average man may have control over certain private machines of his own, such as his car of his personal computer, but control over large systems of machines will be in the hands of a tiny elite -- just as it is today, but with two difference. Due to improved techniques the elite will have greater control over the masses; and because human work will no longer be necessary the masses will be superfluous, a useless burden on the system. If the elite is ruthless the may simply decide to exterminate the mass of humanity. If they are humane they may use propaganda or other psychological or biological techniques to reduce the birth rate until the mass of humanity becomes extinct, leaving the world to the elite. Or, if the elite consist of soft-hearted liberals, they may decide to play the role of good shepherds to the rest of the human race. They will see to it that everyone's physical needs are satisfied, that all children are raised under psychologically hygienic conditions, that everyone has a wholesome hobby to keep him busy, and that anyone who may become dissatisfied undergoes "treatment" to cure his "problem." Of course, life will be so purposeless that people will have to be biologically or psychologically engineered either to remove their need for the power process or to make them "sublimate" their drive for power into some harmless hobby. These engineered human beings may be happy in such a society, but they most certainly will not be free. They will have been reduced to the status of domestic animals.

There is nothing new about prophecies to the effect that the end of the world is near if we do not repent. What is new is that such a prophecy is now true, for two obvious reasons. First, nuclear weapons give us the means to wipe ourselves out quickly: no humans possessed this means before. Second, we already appropriate about forty per cent of the Earth’s net productivity (that is, the net energy captured from sunlight). With the world’s human population now doubling every forty-one years, we will soon have reached the biological limit to growth, at which point we will have to start fighting each other in deadly earnest for a slice of the world’s fixed pie of resources. In addition, given the present rate at which we are exterminating species, most of the world’s species will become extinct or endangered within the next century, but we depend on many species for our own life support.

So far as we know, the tiny fragments of the universe embodied in man are the only centers of thought and responsibility in the visible world. If that be so, the appearance of the human mind has been so far the ultimate stage in the awakening of the world; and all that has gone before, the striving of myriad centers that have taken the risks of living and believing, seem to have all been pursuing, along rival lines, the aim now achieved by us up to this point. They are all akin to us, for all these centers - those which led up to our own existence and the far more numerous others which produced different lines of which many are extinct - may be seen engaged in the same endeavor towards ultimate liberation. We may envisage then a cosmic field which called forth all these centers by offering them a short-lived, limited, hazardous opportunity for making some progress of their own towards an unthinkable consummation. And that is also, I believe, how a Christian is placed when worshiping God.

The notion that we should promote “happy” or “humane” exploitation as “baby steps” ignores that welfare reforms do not result in providing significantly greater protection for animal interests; in fact, most of the time, animal welfare reforms do nothing more than make animal exploitation more economically productive by focusing on practices, such as gestation crates, the electrical stunning of chickens, or veal crates, that are economically inefficient in any event. Welfare reforms make animal exploitation more profitable by eliminating practices that are economically vulnerable. For the most part, those changes would happen anyway and in the absence of animal welfare campaigns precisely because they do rectify inefficiencies in the production process. And welfare reforms make the public more comfortable about animal exploitation. The “happy” meat/animal products movement is clear proof of that. We would never advocate for “humane” or "happy” human slavery, rape, genocide, etc. So, if we believe that animals matter morally and that they have an interest not only in not suffering but in continuing to exist, we should not be putting our time and energy into advocating for “humane” or “happy” animal exploitation.

Similar ecological disasters occurred on almost every one of the thousands of islands that pepper the Atlantic Ocean, Indian Ocean, Arctic Ocean and Mediterranean Sea. Archaeologists have discovered on even the tiniest islands evidence of the existence of birds, insects and snails that lived there for countless generations, only to vanish when the first human farmers arrived. None but a few extremely remote islands escaped man’s notice until the modern age, and these islands kept their fauna intact. The Galapagos Islands, to give one famous example, remained uninhabited by humans until the nineteenth century, thus preserving their unique menagerie, including their giant tortoises, which, like the ancient diprotodons, show no fear of humans. The First Wave Extinction, which accompanied the spread of the foragers, was followed by the Second Wave Extinction, which accompanied the spread of the farmers, and gives us an important perspective on the Third Wave Extinction, which industrial activity is causing today. Don’t believe tree-huggers who claim that our ancestors lived in harmony with nature. Long before the Industrial Revolution, Homo sapiens held the record among all organisms for driving the most plant and animal species to their extinctions. We have the dubious distinction of being the deadliest species in the annals of biology. Perhaps if more people were aware of the First Wave and Second Wave extinctions, they’d be less nonchalant about the Third Wave they are part of. If we knew how many species we’ve already eradicated, we might be more motivated to protect those that still survive. This is especially relevant to the large animals of the oceans.

I found myself drawn to biology, with all its frustrating yet fascinating complexities. When I was twelve, I remember reading about axolotls, which are basically a species of salamander that has evolved to remain permanently in the aquatic larval stage. They manage to keep their gills (rather than trading them in for lungs, like salamanders or frogs) by shutting down metamorphosis and becoming sexually mature in the water. I was completely flabbergasted when I read that by simply giving these creatures the “metamorphosis hormone” (thyroid extract) you could make the axolotl revert back into the extinct, land-dwelling, gill-less adult ancestor that it had evolved from. You could go back in time, resurrecting a prehistoric animal that no longer exists anywhere on Earth. I also knew that for some mysterious reason adult salamanders don’t regenerate amputated legs but the tadpoles do. My curiosity took me one step further, to the question of whether an axolotl—which is, after all, an “adult tadpole”—would retain its ability to regenerate a lost leg just as a modern frog tadpole does. And how many other axolotl-like beings exist on Earth, I wondered, that could be restored to their ancestral forms by simply giving them hormones? Could humans—who are after all apes that have evolved to retain many juvenile qualities—be made to revert to an ancestral form, perhaps something resembling Homo erectus, using the appropriate cocktail of hormones? My mind reeled out a stream of questions and speculations, and I was hooked on biology forever. I found mysteries and possibilities everywhere.

If we are ever going to see a paradigm shift, we have to be clear about how we want the present paradigm to shift. We must be clear that veganism is the unequivocal baseline of anything that deserves to be called an “animal rights” movement. If “animal rights” means anything, it means that we cannot morally justify any animal exploitation; we cannot justify creating animals as human resources, however “humane” that treatment may be. We must stop thinking that people will find veganism “daunting” and that we have to promote something less than veganism. If we explain the moral ideas and the arguments in favor of veganism clearly, people will understand. They may not all go vegan immediately; in fact, most won’t. But we should always be clear about the moral baseline. If someone wants to do less as an incremental matter, let that be her/his decision, and not something that we advise to do. The baseline should always be clear. We should never be promoting “happy” or “humane” exploitation as morally acceptable.

My difficulties lay deeper. It was more than I could believe that Jesus was the only incarnate son of God, and that only he who believed in him would have everlasting life. If God could have sons, all of us were His sons. If Jesus was like God, or God Himself, then all men were like God and could be God Himself. My reason was not ready to believe literally that Jesus by his death and by his blood redeemed the sins of the world. Metaphorically there might be some truth in it. Again, according to Christianity only human beings had souls, and not other living beings, for whom death meant complete extinction; while I held a contrary belief. I could accept Jesus as a martyr, an embodiment of sacrifice, and a divine teacher, but not as the most perfect man ever born. His death on the Cross was a great example to the world, but that there was anything like a mysterious or miraculous virtue in it my heart could not accept. The pious lives of Christians did not give me anything that the lives of men of other faiths had failed to give. I had seen in other lives just the same reformation that I had heard of among Christians. Philosophically there was nothing extraordinary in Christian principles. From the point of view of sacrifice, it seemed to me that the Hindus greatly surpassed the Christians. It was impossible for me to regard Christianity as a perfect religion or the greatest of all religions.

The late twentieth century has witnessed a remarkable growth in scientific interest in the subject of extinction. It is hardly a new subject—Baron Georges Cuvier had first demonstrated that species became extinct back in 1786, not long after the American Revolution. Thus the fact of extinction had been accepted by scientists for nearly three-quarters of a century before Darwin put forth his theory of evolution. And after Darwin, the many controversies that swirled around his theory did not often concern issues of extinction. On the contrary, extinction was generally considered as unremarkable as a car running out of gas. Extinction was simply proof of failure to adapt. How species adapted was intensely studied and fiercely debated. But the fact that some species failed was hardly given a second thought. What was there to say about it? However, beginning in the 1970s, two developments began to focus attention on extinction in a new way. The first was the recognition that human beings were now very numerous, and were altering the planet at a very rapid rate—eliminating traditional habitats, clearing the rain forest, polluting air and water, perhaps even changing global climate. In the process, many animal species were becoming extinct. Some scientists cried out in alarm; others were quietly uneasy. How fragile was the earth’s ecosystem? Was the human species engaged in behavior that would eventually lead to its own extinction?

Consider the genesis of a single-celled embryo produced by the fertilization of an egg by a sperm. The genetic material of this embryo comes from two sources: paternal genes (from sperm) and maternal genes (from eggs). But the cellular material of the embryo comes exclusively from the egg; the sperm is no more than a glorified delivery vehicle for male DNA—a genome equipped with a hyperactive tail. Aside from proteins, ribosomes, nutrients, and membranes, the egg also supplies the embryo with specialized structures called mitochondria. These mitochondria are the energy-producing factories of the cell; they are so anatomically discrete and so specialized in their function that cell biologists call them “organelles”—i.e., mini-organs resident within cells. Mitochondria, recall, carry a small, independent genome that resides within the mitochondrion itself—not in the cell’s nucleus, where the twenty-three pairs of chromosomes (and the 21,000-odd human genes) can be found. The exclusively female origin of all the mitochondria in an embryo has an important consequence. All humans—male or female—must have inherited their mitochondria from their mothers, who inherited their mitochondria from their mothers, and so forth, in an unbroken line of female ancestry stretching indefinitely into the past. (A woman also carries the mitochondrial genomes of all her future descendants in her cells; ironically, if there is such a thing as a “homunculus,” then it is exclusively female in origin—technically, a “femunculus”?) Now imagine an ancient tribe of two hundred women, each of whom bears one child. If the child happens to be a daughter, the woman dutifully passes her mitochondria to the next generation, and, through her daughter’s daughter, to a third generation. But if she has only a son and no daughter, the woman’s mitochondrial lineage wanders into a genetic blind alley and becomes extinct (since sperm do not pass their mitochondria to the embryo, sons cannot pass their mitochondrial genomes to their children). Over the course of the tribe’s evolution, tens of thousands of such mitochondrial lineages will land on lineal dead ends by chance, and be snuffed out. And here is the crux: if the founding population of a species is small enough, and if enough time has passed, the number of surviving maternal lineages will keep shrinking, and shrinking further, until only a few are left. If half of the two hundred women in our tribe have sons, and only sons, then one hundred mitochondrial lineages will dash against the glass pane of male-only heredity and vanish in the next generation. Another half will dead-end into male children in the second generation, and so forth. By the end of several generations, all the descendants of the tribe, male or female, might track their mitochondrial ancestry to just a few women. For modern humans, that number has reached one: each of us can trace our mitochondrial lineage to a single human female who existed in Africa about two hundred thousand years ago. She is the common mother of our species. We do not know what she looked like, although her closest modern-day relatives are women of the San tribe from Botswana or Namibia. I find the idea of such a founding mother endlessly mesmerizing. In human genetics, she is known by a beautiful name—Mitochondrial Eve.

When an animal dies, another of the same species may cling to the body, eat the body, or look bored. Bees expel dead bodies from the hive or, if that is impossible, embalm them in honey. Elephants "say" a ritualistic good-bye, and touch their dead before slowly walking away. Corvids often accept the death of a companion without much fuss, but they at times have “funerals,” where scores of birds lament over the corpse of a deceased crow. But it is a bit odd that people should investigate whether animals “comprehend death,” as if human beings understood what it means to die. Is death a prelude to reincarnation? A portal to Heaven or Hell? Complete extinction? Union with all life? Or something else? All of these views can at times be comforting, yet people usually fear death, quite regardless of what they claim to believe. In the natural world, killing seems a casual affair. Human beings, of course, kill on a massive scale, but most of us can only kill, if at all, by softening the impact of the deed through rituals such as drink or prayer. The strike of a spider, a heron, or a cat is swift and, seemingly, without inhibition or remorse. They pounce with a confidence that could indicate ignorance, indifference, or else profound knowledge. Could this be, perhaps, because animals cannot conceive of killing, since they are not aware of death? Could it be because they understand death well, far better than do human beings? If animals envision the world not in terms of abstract concepts but sensuous images, the soul might appear as a unique scent, a rhythmic motion, or a tone of voice. Death would be the absence of these, though without that absolute finality that we find so severe. Perhaps the heron that snaps a fish thinks his meal lives on, as he one day will, in the form of currents in the pond.

Because complex animals can evolve their behavior rapidly. Changes can occur very quickly. Human beings are transforming the planet, and nobody knows whether it’s a dangerous development or not. So these behavioral processes can happen faster than we usually think evolution occurs. In ten thousand years human beings have gone from hunting to farming to cities to cyberspace. Behavior is screaming forward, and it might be nonadaptive. Nobody knows. Although personally, I think cyberspace means the end of our species.” “Yes? Why is that?” “Because it means the end of innovation,” Malcolm said. “This idea that the whole world is wired together is mass death. Every biologist knows that small groups in isolation evolve fastest. You put a thousand birds on an ocean island and they’ll evolve very fast. You put ten thousand on a big continent, and their evolution slows down. Now, for our own species, evolution occurs mostly through our behavior. We innovate new behavior to adapt. And everybody on earth knows that innovation only occurs in small groups. Put three people on a committee and they may get something done. Ten people, and it gets harder. Thirty people, and nothing happens. Thirty million, it becomes impossible. That’s the effect of mass media—it keeps anything from happening. Mass media swamps diversity. It makes every place the same. Bangkok or Tokyo or London: there’s a McDonald’s on one corner, a Benetton on another, a Gap across the street. Regional differences vanish. All differences vanish. In a mass-media world, there’s less of everything except the top ten books, records, movies, ideas. People worry about losing species diversity in the rain forest. But what about intellectual diversity—our most necessary resource? That’s disappearing faster than trees. But we haven’t figured that out, so now we’re planning to put five billion people together in cyberspace. And it’ll freeze the entire species. Everything will stop dead in its tracks. Everyone will think the same thing at the same time. Global uniformity. Oh, that hurts. Are you done?” “Almost,” Harding said. “Hang on.” “And believe me, it’ll be fast. If you map complex systems on a fitness landscape, you find the behavior can move so fast that fitness can drop precipitously. It doesn’t require asteroids or diseases or anything else. It’s just behavior that suddenly emerges, and turns out to be fatal to the creatures that do it. My idea was that dinosaurs—being complex creatures—might have undergone some of these behavioral changes. And that led to their extinction.

There was once a town in the heart of America where all life seemed to live in harmony with its surroundings. The town lay in the midst of a checkerboard of prosperous farms, with fields of grain and hillsides of orchards where, in spring, white clouds of bloom drifted above the green fields. In autumn, oak and maple and birch set up a blaze of color that flamed and flickered across a backdrop of pines. Then foxes barked in the hills and deer silently crossed the fields, half hidden in the mists of the fall mornings. Along the roads, laurel, viburnum, and alder, great ferns and wildflowers delighted the traveler's eye through much of the year. Even in winter the roadsides were places of beauty, where countless birds came to feed on the berries and on the seed heads of the dried weeds rising above the snow. The countryside was, in fact, famous for the abundance and variety of its bird life, and when the flood of migrants was pouring through in spring and fall people traveled from great distances to observe them. Others came to fish the streams, which flowed clear and cold out of the hills and contained shady pools where trout lay. So it had been from the days many years ago when the first settlers raised their homes, sank their wells, and built their barns. Then a strange blight crept over the area and everything began to change. Some evil spell had settled on the community: mysterious maladies swept the flocks of chickens, the cattle, and sheep sickened and died. Everywhere was a shadow of death. The farmers spoke of much illness among their families. In the town the doctors had become more and more puzzled by new kinds of sickness appearing among their patients. There had been sudden and unexplained deaths, not only among adults but even among children whoe would be stricken suddently while at play and die within a few hours. There was a strange stillness. The birds, for example--where had they gone? Many people spoke of them, puzzled and disturbed. The feeding stations in the backyards were deserted. The few birds seen anywhere were moribund; they trembled violently and could not fly. It was a spring without voices. On the mornings that had once throbbed with the dawn chorus of robins, catbirds, doves, jays, wrens, and scores of other bird voices there was no sound; only silence lay over the fields and woods and marsh. On the farms the hens brooded, but no chicks hatched. The farmers complained that they were unable to raise any pigs--the litters were small and the young survived only a few days. The apple trees were coming into bloom but no bees droned among the blossoms, so there was no pollination and there would be no fruit. The roadsides, once so attractive, were now lined with browned and withered vegetation as though swept by fire. These, too, were silent, deserted by all living things. Even the streams were not lifeless. Anglers no longer visited them, for all the fish had died. In the gutters under the eaves and between the shingles of the roofs, a white granular powder still showed a few patches; some weeks before it had fallen like snow upon the roofs and the lawns, the fields and streams. No witchcraft, no enemy action had silenced the rebirth of life in this stricken world. The people had done it to themselves.

All social orders command their members to imbibe in pipe dreams of posterity, the mirage of immortality, to keep them ahead of the extinction that would ensue in a few generations if the species did not replenish itself. This is the implicit, and most pestiferous, rationale for propagation: to become fully integrated into a society, one must offer it fresh blood. Naturally, the average set of parents does not conceive of their conception as a sacrificial act. These are civilized human beings we are talking about, and thus they are quite able to fill their heads with a panoply of less barbaric rationales for reproduction, among them being the consolidation of a spousal relationship; the expectation of new and enjoyable experiences in the parental role; the hope that one will pass the test as a mother or father; the pleasing of one’s own parents, not to forget their parents and possibly a great-grandparent still loitering about; the serenity of taking one’s place in the seemingly deathless lineage of a familial enterprise; the creation of individuals who will care for their paternal and maternal selves in their dotage; the quelling of a sense of guilt or selfishness for not having done their duty as human beings; and the squelching of that faint pathos that is associated with the childless. Such are some of the overpowering pressures upon those who would fertilize the future. These pressures build up in people throughout their lifetimes and must be released, just as everyone must evacuate their bowels or fall victim to a fecal impaction. And who, if they could help it, would suffer a building, painful fecal impaction? So we make bowel movements to relieve this pressure. Quite a few people make gardens because they cannot stand the pressure of not making a garden. Others commit murder because they cannot stand the pressure building up to kill someone, either a person known to them or a total stranger. Everything is like that. Our whole lives consist of metaphorical as well as actual bowel movements, one after the other. Releasing these pressures can have greater or lesser consequences in the scheme of our lives. But they are all pressures, all bowel movements of some kind. At a certain age, children are praised for making a bowel movement in the approved manner. Later on, the praise of others dies down for this achievement and our bowel movements become our own business, although we may continue to praise ourselves for them. But overpowering pressures go on governing our lives, and the release of these essentially bowel-movement pressures may once again come up for praise, congratulations, and huzzahs of all kinds.

Scholars discern motions in history & formulate these motions into rules that govern the rises & falls of civilizations. My belief runs contrary, however. To wit: history admits no rules, only outcomes. What precipitates outcomes? Vicious acts & virtuous acts. What precipitates acts? Belief. Belief is both prize & battlefield, within the mind & in the mind's mirror, the world. If we believe humanity is a ladder of tribes, a colosseum of confrontation, exploitation & bestiality, such a humanity is surely brought into being, & history's Horroxes, Boerhaaves & Gooses shall prevail. You & I, the moneyed, the privileged, the fortunate, shall not fare so badly in this world, provided our luck holds. What of it if our consciences itch? Why undermine the dominance of our race, our gunships, our heritage & our legacy? Why fight the 'natural' (oh, weaselly word!) order of things? Why? Because of this: -- one fine day, a purely predatory world shall consume itself. Yes, the devil shall take the hindmost until the foremost is the hindmost. In an individual, selfishness uglifies the soul; for the human species, selfishness is extinction. Is this the entropy written in our nature? If we believe that humanity may transcend tooth & claw, if we believe divers [sic] races & creeds can share this world as peaceably as the orphans share their candlenut tree, if we believe leaders must be just, violence muzzled, power accountable & the riches of the Earth & its Oceans shared equitably, such a world will come to pass. I am not deceived. It is the hardest of worlds to make real. Tortuous advances won over generations can be lost by a single stroke of a myopic president's pen or a vainglorious general's sword. A life spent shaping a world I want Jackson to inherit, not one I fear Jackson shall inherit, this strikes me as a life worth the living. Upon my return to San Francisco, I shall pledge myself to the Abolitionist cause, because I owe my life to a self-freed slave & because I must begin somewhere. I hear my father-in-law's response. 'Oho, fine, Whiggish sentiments, Adam. But don't tell me about justice! Ride to Tennessee on an ass & convince the red-necks that they are merely white-washed negroes & their negroes are black-washed Whites! Sail to the Old World, tell 'em their imperial slaves' rights are as inalienable as the Queen of Belgium's! Oh, you'll grow hoarse, poor & grey in caucuses! You'll be spat on, shot at, lynched, pacified with medals, spurned by backwoodsmen! Crucified! Naïve, dreaming Adam. He who would do battle with the many-headed hydra of human nature must pay a world of pain & his family must pay along with him! & only as you gasp your dying breath shall you understand, your life amounted to no more than one drop in a limitless ocean!' Yet what is any ocean but a multitude of drops?
