Photosynthesis Quotes

I want my words to illuminate like the sun, as I give my daily lecture on photosynthesis to my houseplants.

Look, Sage. I don't know much about chemistry or computer hacking or photosynthery, but this is something I've got a lot of experience with." I think he mean photosynthesis, but I didn't correct him. "Use my knowledge. Don't let it go to waste.

If you don't understand how something works, never mind: just give up and say God did it. You don't know how the nerve impulse works? Good! You don't understand how memories are laid down in the brain? Excellent! Is photosynthesis a bafflingly complex process? Wonderful! Please don't go to work on the problem, just give up, and appeal to God.

Adrian looked over at me again. “Who knows more about male weakness: you or me?” “Go on.” I refused to directly answer the question. “Get a new dress. One that shows a lot of skin. Short. Strapless. Maybe a push-up bra too.” He actually had the audacity to do a quick assessment of my chest. “Eh, maybe not. But definitely some high heels.” “Adrian,” I exclaimed. “You’ve seen how Alchemists dress. Do you think I can really wear something like that?” He was unconcerned. “You’ll make it work. You’ll change clothes or something. But I’m telling you, if you want to get a guy to do something that might be difficult, then the best way is to distract him so that he can’t devote his full brainpower to the consequences.” “You don’t have a lot of faith in your own gender.” “Hey, I’m telling you the truth. I’ve been distracted by sexy dresses a lot.” I didn’t really know if that was a valid argument, seeing as Adrian was distracted by a lot of things. Fondue. T-shirts. Kittens. “And so, what then? I show some skin, and the world is mine?” “That’ll help.” Amazingly, I could tell he was dead serious. “And you’ve gotta act confident the whole time, like it’s already a done deal. Then make sure when you’re actually asking for what you want that you tell him you’d be ‘so, so grateful.’ But don’t elaborate. His imagination will do half the work for you. ” I shook my head, glad we’d almost reached our destination. I didn’t know how much more I could listen to. “This is the most ridiculous advice I’ve ever heard. It’s also kind of sexist too, but I can’t decide who it offends more, men or women.” “Look, Sage. I don’t know much about chemistry or computer hacking or photosynthery, but this is something I’ve got a lot of experience with.” I think he meant photosynthesis, but I didn’t correct him. “Use my knowledge. Don’t let it go to waste.

I wish that in order to secure his party’s nomination, a presidential candidate would be required to point at the sky and name all the stars; have the periodic table of the elements memorized; rattle off the kings and queens of Spain; define the significance of the Gatling gun; joke around in Latin; interpret the symbolism in seventeenth-century Dutch painting; explain photosynthesis to a six-year-old; recite Emily Dickenson; bake a perfect popover; build a shortwave radio out of a coconut; and know all the words to Hoagy Carmichael’s “Two Sleepy People”, Johnny Cash’s “Five Feet High and Rising”, and “You Got the Silver” by the Rolling Stones...What we need is a president who is at least twelve kinds of nerd, a nerd messiah to come along every four years, acquire the Secret Service code name Poindexter, install a Revenge of the Nerds screen saver on the Oval Office computer, and one by one decrypt our woes.

The essential thing is to recognize that consciousness is a biological process like digestion, lactation, photosynthesis, or mitosis”;

At school you were taught about chemicals in test tubes, equations to describe motion, and maybe something on photosynthesis—about which more later—but in all likelihood you were taught nothing about death, risk, statistics, and the science of what will kill or cure you.

Regular adult Americans are no more capable of doing math than they are of photosynthesis.

It’s horribly cliché, but his smile is beaming—far brighter than the sun. I feel myself bloom with it, as if it’s my own personal version of photosynthesis.

It called to mind something ancient, something pre-evolutionary, or else perhaps a mark of photosynthesis, and he realized to his surprise that there was nothing at all sexual about it; it was more vegetal than sexual.

Nature is really good at capital productivity and capital allocation. Every leaf on every tree is positioned to maximize photosynthesis. Every root on every tree is positioned to maximize nutrient sequestration. And all of the leaves and all of the roots live in service to each other.

A mere two days without eating and you passed out. It must be tough not being able to photosynthesize.

I wish it were different. I wish that we privileged knowledge in politicians, that the ones who know things didn't have to hide it behind brown pants, and that the know-not-enoughs were laughed all the way to the Maine border on their first New Hampshire meet and greet. I wish that in order to secure his party's nomination, a presidential candidate would be required to point at the sky and name all the stars; have the periodic table of the elements memorized; rattle off the kings and queens of Spain; define the significance of the Gatling gun; joke around in Latin; interpret the symbolism in seventeenth-century Dutch painting; explain photosynthesis to a six-year-old; recite Emily Dickinson; bake a perfect popover; build a shortwave radio out of a coconut; and know all the words to Hoagy Carmichael's "Two Sleepy People," Johnny Cash's "Five Feet High and Rising," and "You Got the Silver" by the Rolling Stones. After all, the United States is the greatest country on earth dealing with the most complicated problems in the history of the world--poverty, pollution, justice, Jerusalem. What we need is a president who is at least twelve kinds of nerd, a nerd messiah to come along every four years, acquire the Secret Service code name Poindexter, install a Revenge of the Nerds screen saver on the Oval Office computer, and one by one decrypt our woes.

This is a green world, with animals comparatively few and small, and dependent on the leaves. By leaves we live.

do not take pictures to please the public, the photo should be spontaneous and free

I listened to Karen Woo give an explaination of photosynthesis once," he said. "God only knows why they were discussing photosynthesis.They hung on her every word, like she was a PBS special. Her explaination didn't even involve sunlight. These people will believe anything. They will say anything.

These kids today. Back then, we couldn't afford photosynthesis. We had to build oxygen from scratch with an atom smasher.

Science is spectrum analysis. Art is Photosynthesis.

He had a love affair with photosynthesis. He could talk about moss for an hour. He said that plants carried wisdom humans would never be around long enough to understand.

She inhales the admiration and breathes out arrogance, her own bespoke photosynthesis.

Wine is so complex, I mused. Thousands of experts and hundreds of thousands of amateur experts would rhapsodize or vilify the vinification of these seemingly simple bunches of grapes. But in the end, it was just these innocuous clusters, photosynthesis, rain or no rain, cool ocean breezes, alluvial soils, that produced these epiphanies in the bottle hundreds and thousands of miles away.

The term ‘mycorrhiza’ is made from the Greek words for ‘fungus’ and ‘root’. It is itself a collaboration or entanglement; and as such a reminder of how language has its own sunken system of roots and hyphae, through which meaning is shared and traded. The relationship between mycorrhizal fungi and the plants they connect is ancient – around 450 million years old – and largely one of mutualism. In the case of the tree–fungi mutualism, the fungi siphon off carbon that has been produced in the form of glucose by the trees during photosynthesis, by means of chlorophyll that the fungi do not possess. In turn, the trees obtain nutrients such as phosphorus and nitrogen that the fungi have acquired from the soil through which they grow, by means of enzymes that the trees lack.

At school you were taught about chemicals in test tubes, equations to describe motion, and maybe something on photosynthesis – about which more later – but in all likelihood you were taught nothing about death, risk, statistics, and the science of what will kill or cure you. The hole in our culture is gaping: evidence-based medicine, the ultimate applied science, contains some of the cleverest ideas from the past two centuries, it has saved millions of lives, but there has never once been a single exhibit on the subject in London’s Science Museum.

We live now in an information technology. Flowers have always lived in an information technology. Flowers gather information all day. At night, they process it. This is called photosynthesis. As our neocortex comes into full use, we, too will practice photosyntesis. As a matter of fact, we already do, but compared for flowers, our kind is primitive and limited. For one thing, information gathered from daily newspapers, soap operas, sales conferences and coffee klatches is inferior to information gathered from sunlight.... Either because our data is insufficient or because our processing equipment is not fully on line, our own noctural processing is part-time work. The information our conscious minds receive during waking hours is processed by our unconscious during so called "deep sleep". We are in deep sleep only two or three hours a night. For the rest of our sleeping session, the unconscious mind is off duty. It gets bored. It craves recreation. So it plays with the material at hand. In a sense, it palys with itself. It scrambles memories, juggles images, rearranges data, invents scary or titillating stories. This is what we call "dreaming".

Resurrection plants are usually tiny, no bigger than your fist. They are ugly and small and useless and special. When it rains, their leaves puff up but do not become green for forty-eight hours because it takes time for photosynthesis to start up. During those strange days of its reawakening the plant lives off of pure concentrated sugar, an intense sustained infusion of sweetness, a year's worth of sucrose coursing through its veins in just one day. This little plant has done the impossible: it has transcended the wilted brown of death. The miracle is not sustainable, of course, and within a day or two things will inevitably go back to normal. Such a crazy life takes its toll, and in the long term, even a resurrection plant withers and dies completely. But for a brief, glorious moment it knows something that no other plant has ever known: how to grow without being green.

[N]early every creationist debater will mention the second law of thermodynamics and argue that complex systems like the earth and life cannot evolve, because the second law seems to say that everything in nature is running down and losing energy, not getting more complex. But that's NOT what the second law says; every creationist has heard this but refuses to acknowledge it. The second law only applies to closed systems, like a sealed jar of heated gases that gradually cools down and loses energy. But the earth is not a closed system -- it constantly gets new energy from the sun, and this (through photosynthesis) is what powers life and makes it possible for life to become more complex and evolve. It seems odd that the creationists continue to misuse the second law of thermodynamics when they have been corrected over and over again, but the reason is simple: it sounds impressive to their audience with limited science education, and if a snow job works, you stay with it.

Originally, the atoms of carbon from which we’re made were floating in the air, part of a carbon dioxide molecule. The only way to recruit these carbon atoms for the molecules necessary to support life—the carbohydrates, amino acids, proteins, and lipids—is by means of photosynthesis. Using sunlight as a catalyst the green cells of plants combine carbon atoms taken from the air with water and elements drawn from the soil to form the simple organic compounds that stand at the base of every food chain. It is more than a figure of speech to say that plants create life out of thin air.

I was clinging to this tree so passionately that I might very well have committed an act of photosynthesis with it.

no other mechanism known to humankind is as effective in addressing global warming as capturing carbon dioxide from the air through photosynthesis.

Remember this: men and pornography are like plants and sunshine. To me, porn is photosynthesis.

photosynthesis: a feat of chemical engineering underpinning creation’s entire cathedral.

It was made clear to me that I wasn’t supposed to trouble the moody Creator with any pesky questions about the eccentricities of His cosmic system. So when I asked about stuff that confused me, like “How come we’re praying for the bar to be shut down when Jesus himself turned water into wine?”, I was shushed and told to have faith. Thus my idea of heaven was that I got to spend eternity sitting at the feet of God, grilling Him. “Let me get this straight,” I’d say by way of introduction. “It’s your position that every person ever born has to suffer because Eve couldn’t resist a healthy between-meals snack?” Once I got the metaphysical queries out of the way I could satisfy my curiosity about how He came up with stuff I was learning about in school, like photosynthesis.

I don’t want to be infected with somebody’s photosynthesis as my osmosis is advancing from metamorphosis to trypanosomiasis which is a crisis – so said the analysis of the diagnosis conducted by Francis.

Cities are like the mitochondria in our animal cells—they are consumers, fed by the autotrophs, the photosynthesis of a distant green landscape. We could lament that urban dwellers have little means of exercising direct reciprocity with the land. Yet while city folks may be separated from the sources of what they consume, they can exercise reciprocity through how they spend their money. While the digging of the leeks and the digging of the coal may be too far removed to see, we consumers have a potent tool of reciprocity right in our pockets. We can use our dollars as the indirect currency of reciprocity.

Sixty-six million years ago, an asteroid impact caused a dust cloud so huge that darkness may have pervaded Earth for two years, virtually stopping photosynthesis and leading to the extinction of 75 percent of land animals. Measured against these disasters, we're just not that important. When Earth is done with us, it'll be like, "Well, that Human Pox wasn't great, but at least I didn't get Large Asteroid Syndrome.

There is a bench in the back of my garden shaded by Virginia creeper, climbing roses, and a white pine where I sit early in the morning and watch the action. Light blue bells of a dwarf campanula drift over the rock garden just before my eyes. Behind it, a three-foot stand of aconite is flowering now, each dark blue cowl-like corolla bowed for worship or intrigue: thus its common name, monkshood. Next to the aconite, black madonna lilies with their seductive Easter scent are just coming into bloom. At the back of the garden, a hollow log, used in its glory days for a base to split kindling, now spills white cascade petunias and lobelia. I can't get enough of watching the bees and trying to imagine how they experience the abundance of, say, a blue campanula blosssom, the dizzy light pulsing, every fiber of being immersed in the flower. ... Last night, after a day in the garden, I asked Robin to explain (again) photosynthesis to me. I can't take in this business of _eating light_ and turning it into stem and thorn and flower... I would not call this meditation, sitting in the back garden. Maybe I would call it eating light. Mystical traditions recognize two kinds of practice: _apophatic mysticism_, which is the dark surrender of Zen, the Via Negativa of John of the Cross, and _kataphatic mysticism_, less well defined: an openhearted surrender to the beauty of creation. Maybe Francis of Assissi was, on the whole, a kataphatic mystic, as was Thérèse of Lisieux in her exuberant momemnts: but the fact is, kataphatic mysticism has low status in religious circles. Francis and Thérèse were made, really made, any mother superior will let you know, in the dark nights of their lives: no more of this throwing off your clothes and singing songs and babbling about the shelter of God's arms. When I was twelve and had my first menstrual period, my grandmother took me aside and said, 'Now your childhood is over. You will never really be happy again.' That is pretty much how some spiritual directors treat the transition from kataphatic to apophatic mysticism. But, I'm sorry, I'm going to sit here every day the sun shines and eat this light. Hung in the bell of desire.

The family tree of each of us is graced by all those great inventors: the beings who first tried out self-replication, the manufacture of protein machine tools, the cell, cooperation, predation, symbiosis, photosynthesis, breathing oxygen, sex, hormones, brains, and all the rest-inventions we use, some of them, minute-by-minute without ever wondering who devised them and how much we owe to these unknown benefactors, in a chain 100 billion links long.

seaweed uses photosynthesis to pull carbon from the atmosphere and the water; some varieties are capable of absorbing five times more carbon dioxide than land-based plants. And seaweed is one of the fastest-growing plants in the world.

We’ve known since 2007 that there’s superposition in chlorophyll, for instance. Photosynthesis has a ninety-five percent energy-transfer efficiency rate, which is better than anything we can engineer. Plants achieve that by using superposition to simultaneously try all the possible pathways between their light-collecting molecules and their reaction-center proteins so that energy is always sent down the most efficient route; it’s a form of biological quantum computing.

A rising tower of wood and needles and branches and great slabs of bark that has grown for hundreds of years. An impossible castle made from air and sunlight, fixed in place by the power of photosynthesis and chlorophyll. Magic. With lights.

If it was the warmth of the sun, and not its light, that produced this operation, it would follow, that, by warming the water near the fire about as much as it would have been in the sun, this very air would be produced; but this is far from being the case..

All the world’s plants capture only about 3,000 of those solar exajoules through the process of photosynthesis.3 All human activities and industries put together consume about 500 exajoules annually, equivalent to the amount of energy earth receives from the sun in just ninety minutes.

Only a tiny proportion of the sun’s energy reaches us, yet it amounts to 3,766,800 exajoules of energy each year (a joule is a unit of energy in the metric system, about the amount you expend to lift a small apple one yard straight up; an exajoule is a billion billion joules – that’s a lot of apples). All the world’s plants capture only about 3,000 of those solar exajoules through the process of photosynthesis. All human activities and industries put together consume about 500 exajoules annually, equivalent to the amount of energy earth receives from the sun in just ninety minutes. And that’s only solar energy.

In all my years in the wild, I’ve never met Mother Nature or Mr. Photosynthesis. Humans tend to try to make sense of things and are always searching for scientific reasons to explain the world’s riddles. But if you do not believe in a Creator, your options are limited in trying to explain the functions of Earth, let alone the universe. Who built this place? Where did I come from? Where did you come from? As Hebrews 3:4 says, “For every house is built by someone, but God is the builder of everything.” The Hebrews writer was actually comparing Moses and Jesus, but he delivered principles that I have come to believe are fundamental to life’s questions. To me it would be silly to claim someone’s physical home might not have been built just because you didn’t see it being built. We know someone built our homes, neighborhoods, and skyscrapers because of their design, even though they may have been constructed before we were even born.

So, let's get back to why the roots are the most important part of a tree. Conceivably, this is where the tree equivalent of a brain is located. Brain? you ask. Isn't that a bit farfetched? Possibly, but now we know that trees can learn. This means they must store experiences somewhere, and therefore, there must be some kind of a storage mechanism inside the organism. Just where it is, no one knows, but the roots are the part of the tree best suited to the task. The old spruce in Sweden also shows that what grows underground is the most permanent part of the tree-and where else would it store important information over a long period of time? Moreover, current research shows that a tree's delicate root networks is full of surprises. It is now an accepted fact that the root network is in charge of all chemical activity in the tree. And there's nothing earth shattering about that. Many of our internal processes are also regulated by chemical messengers. Roots absorb substances and bring them into the tree. In the other direction, they deliver the products of photosynthesis to the tree's fungal partners and even route warning signals to neighboring trees. But a brain? For there to be something we would recognize as a brain, neurological processes must be involved, and for these, in addition to chemical messages, you need electrical impulses. And these are precisely what we can measure in the tree, and we've been able to do so since as far back as the nineteenth century. For some years now, a heated controversy has flared up among scientists. Can plants think? Are they intelligent?

It’s a miracle, she tells her students, photosynthesis: a feat of chemical engineering underpinning creation’s entire cathedral. All the razzmatazz of life on Earth is a free-rider on that mind-boggling magic act. The secret of life: plants eat light and air and water, and the stored energy goes on to make and do all things.

Chloroplasts bear chlorophyll; they give the green world its color, and they carry out the business of photosynthesis. Around the inside perimeter of each gigantic cell trailed a continuous loop of these bright green dots. They spun . . . they pulsed, pressed, and thronged . . . they shone, they swarmed in ever-shifting files around and around the edge of the cell; they wandered, they charged, they milled, raced . . . they flowed and trooped greenly . . . All the green in the planted world consists of these whole, rounded chloroplasts . . . If you analyze a molecule of chlorophyll itself, what you get is one hundred thirty-six atoms of hydrogen, carbon, oxygen, and nitrogen arranged in an exact and complex relationship around a central ring. At the ring’s center is a single atom of magnesium. Now: If you remove the atom of magnesium and in its place put an atom of iron, you get a molecule of hemoglobin. The iron atom combines with all the other atoms to make red blood, the streaming red dots in the goldfish’s tail.

I routinely use my blue sky "Device" and it works very well for me.

The smell of azaleas and the sleepy smell of sun working with chlorophyll filled the air.

You can energize the human mind and body with light.

The mind splices fragments of sensation and language into story after story. The blood in my veins and every blade of grass is oxygen, sugar, photosynthesis, genetic expression, electrochemistry, and time. I watch clouds crush the last bit of pink sky. Breath slips even as I inhale, even as snow falls out of season and mud thaws, even as lightning ignites a late spring.

Many of you remember when Dutch Elm disease swept the East Coast. People in big cities saw the trees die but it didn’t register, in any way at all, that this would compromise oxygen. Think of it, that many trees dying in that short a time span means there is less photosynthesis. Less oxygen is being produced. Therefore pollution in the big cities becomes more pronounced. These basics do not occur to people who work in buildings where the windows don’t open.

Had you been a spectator during only the first three days of creation, you might not have judged it as good. What good are seed-bearing plants with no sun for photosynthesis? In His wisdom God knew the work was good because He knew what was coming next. He knows what’s coming next for you. That’s why He can judge His work in you as good. Give God room to be completely creative. Meet with Him daily as He unfolds the plan in perfect order. He’s really good at what He does.

Living cells must have food in the form of sugar, they must breathe, and they must grow, at least a little. But without leaves-and therefore without photosynthesis-that's impossible. No being on the planet can maintain a centuries-long fast, not even the remains of a tree, and certainly not a stump that has had to survive on its own. It was clear that something else was happening with this stump. It must be getting assistance from neighboring trees, specifically from their roots. Scientists investigating similar situations have discovered that assistance may either be delivered remotely by fungal networks around the root tips-which facilitate nutrient exchange between trees-or the roots themselves may be interconnected. In the case of the stump I had stumbled upon, I couldn't find out what was going on, because I didn't want to injure the old stump by digging around it, but one thing was clear: the surrounding beeches were pumping sugar to the stump to keep it alive.

But Douglas fir and ponderosa pine were both better than the spruce and subalpine fir at minimizing water loss, helping them cope with the drought. They did this by opening their stomata for only a few hours in the morning when the dew was heavy. In these early hours, trees sucked carbon dioxide in through the open pores to make sugar, and in the process, transpired water brought up from the roots. By noon, they slammed their stomata closed, shutting down photosynthesis and transpiration for the day.

...Axelrod also pointed out that TIT FOR TAT interactions lead to cooperation in the natural world even without the benefit of intelligence. Examples include lichens, in which a fungus extracts nutrients from the underlying rock while providing a home for algae that in turn provide the fungus with photosynthesis; the ant-acacia tree, which houses and feeds a type of ant that in turn protects the tree; and the fig tree whose flowers serve as food for fig wasps that in turn pollinate the flowers and scatter the seeds.

Only a tiny proportion of the sun’s energy reaches us, yet it amounts to 3,766,800 exajoules of energy each year (a joule is a unit of energy in the metric system, about the amount you expend to lift a small apple one yard straight up; an exajoule is a billion billion joules – that’s a lot of apples).2 All the world’s plants capture only about 3,000 of those solar exajoules through the process of photosynthesis.3 All human activities and industries put together consume about 500 exajoules annually, equivalent to the amount of energy earth receives from the sun in just ninety minutes.

Such work would never be done if scientists were satisfied with a lazy default such as ‘intelligent design theory’ would encourage. Here is the message that an imaginary ‘intelligent design theorist’ might broadcast to scientists: ‘If you don’t understand how something works, never mind: just give up and say God did it. You don’t know how the nerve impulse works? Good! You don’t understand how memories are laid down in the brain? Excellent! Is photosynthesis a bafflingly complex process? Wonderful!

Please don’t go to work on the problem, just give up, and appeal to God. Dear scientist, don’t work on your mysteries. Bring us your mysteries, for we can use them. Don’t squander precious ignorance by researching it away. We need those glorious gaps as a last refuge for God.

When the rocking stopped Marina tilted her hips back and forth to start it up again. There were layers upon layers of scents inside the hammock—the smell of her own sweat which brought up trace amounts of soap and shampoo; the smell of the hammock itself which was both mildewed and sunbaked with a slight hint of rope; the smell of the boat, gasoline and oil; and the smell of the world outside the boat, the river water and the great factory of leaves pumping oxygen into the atmosphere, the tireless photosynthesis of plants turning sunlight into energy, not that photosynthesis had an odor. Marina inhaled deeply and the scent of the air relaxed her. Brought together, all those

INFECTIOUS DISEASE IS all around us. Infectious disease is a kind of natural mortar binding one creature to another, one species to another, within the elaborate biophysical edifices we call ecosystems. It’s one of the basic processes that ecologists study, including also predation, competition, decomposition, and photosynthesis. Predators are relatively big beasts that eat their prey from outside. Pathogens (disease-causing agents, such as viruses) are relatively small beasts that eat their prey from within. Although infectious disease can seem grisly and dreadful, under ordinary conditions it’s every bit as natural as what lions do to wildebeests and zebras, or what owls do to mice.

Students at the instituted for Environmental Research at RWTH Aachen discovered something amazing about photosynthesis in undisturbed beech forests. Apparently, the trees synchronize their performance so that they are all equally successful. And that is not what one would expect. Each beech tree grows in a unique location, and conditions can vary greatly in just a few yards. The soil can be stony or loose. It can retain a great deal of water or almost no water. It can be full of nutrients or extremely barren. Accordingly, each tree experiences different growing conditions; therefore, each tree grows more quickly or more slowly and produces more or less sugar or wood, and thus you would expect every tree to be photosynthesizing at a different rate. And that's what makes the research results so astounding. The rate of photosynthesis is the same for all the trees. The trees, it seems, are equalizing differences between the strong and the weak. Whether they are thick or thin, all members of the same species are using light to produce the same amount of sugar per leaf. This equalization is taking place underground through the roots. There's obviously a lively exchange going on down there. Whoever has an abundance of sugar hands some over; whoever is running short gets help. Once again, fungi are involved. Their enormous networks act as gigantic redistribution mechanisms. It's a bit like the way social security systems operate to ensure individual members of society don't fall too far behind.

The amount of energy stored in all the fossil fuel on earth is negligible compared to the amount that the sun dispenses every day, free of charge. Only a tiny proportion of the sun’s energy reaches us, yet it amounts to 3,766,800 exajoules of energy each year (a joule is a unit of energy in the metric system, about the amount you expend to lift a small apple one yard straight up; an exajoule is a billion billion joules – that’s a lot of apples).2 All the world’s plants capture only about 3,000 of those solar exajoules through the process of photosynthesis.3 All human activities and industries put together consume about 500 exajoules annually, equivalent to the amount of energy earth receives from the sun in just ninety minutes.4 And that’s only solar energy. In addition, we are surrounded by other enormous sources of energy, such as nuclear energy and gravitational energy, the latter most evident in the power of the ocean tides caused by the moon’s pull on the earth.

That all plants immediately and substantially stem from the element water alone I have learnt from the following experiment. I took an earthern vessel in which I placed two hundred pounds of earth dried in an oven, and watered with rain water. I planted in it a willow tree weighing five pounds. Five years later it had developed a tree weighing one hundred and sixty-nine pounds and about three ounces. Nothing but rain (or distilled water) had been added. The large vessel was placed in earth and covered by an iron lid with a tin-surface that was pierced with many holes. I have not weighed the leaves that came off in the four autumn seasons. Finally I dried the earth in the vessel again and found the same two hundred pounds of it diminished by about two ounces. Hence one hundred and sixty-four pounds of wood, bark and roots had come up from water alone. (1648) [A diligent experiment that was quantitatively correct only as far as it goes. He overlooked the essential role of air and photosynthesis in the growth process]

Young developing leaves on normal trees are often tinged red thanks to a kind of sun block in their delicate tissue. This is anthocyanin, which blocks ultraviolet rays to protect the little leaves. As the leaves grow, the anthocyanin is broken down with the help of an enzyme. A few beeches or maples deviate from the norm because they lack this enzyme. They cannot get rid of the red color, and they retain it even in their mature leaves. Therefore, their leaves strongly reflect red light and waste a considerable portion of the light’s energy. Of course, they still have the blue tones in the spectrum for photosynthesis, but they are not achieving the same levels of photosynthesis as their green-leaved relatives. These red trees keep appearing in Nature, but they never get established and always disappear again. Humans, however, love anything that is different, and so we seek out red varieties and propagate them. One man’s trash is another man’s treasure is one way to describe this behavior, which might stop if people knew more about the trees’ circumstances.

For about 48 weeks of the year an asparagus plant is unrecognizable to anyone except an asparagus grower. Plenty of summer visitors to our garden have stood in the middle of the bed and asked, 'What is this stuff? It's beautiful!' We tell them its the asparagus patch, and they reply, 'No this, these feathery little trees.' An asparagus spear only looks like its picture for one day of its life, usually in April, give or take a month as you travel from the Mason-Dixon Line. The shoot emerges from the ground like a snub nose green snake headed for sunshine, rising so rapidly you can just about see it grow. If it doesn't get it's neck cut off at ground level as it emerges, it will keep growing. Each triangular scale on the spear rolls out into a branch until the snake becomes a four foot tree with delicate needles. Contrary to lore, fat spears are no more tender or mature than thin ones. Each shoot begins life with its own particular girth. In the hours after emergence, it lengthens but does not appreciably fatten. To step into another raging asparagus controversy, white spears are botanically no different from their green colleagues. White shoots have been deprived of sunlight by a heavy mulch pulled up over the plant's crown. European growers go to this trouble for consumers who prefer the stalks before they've had their first blush of photosynthesis. Most Americans prefer the more developed taste of green. Uncharacteristically, we're opting for the better nutritional deal here also. The same plant could produce white or green spears in alternate years, depending on how it is treated. If the spears are allowed to proceed beyond their first exploratory six inches, they'll green out and grow tall and feathery like the house plant known as asparagus fern, which is the next of kin. Older, healthier asparagus plants produce chunkier, more multiple shoots. Underneath lies an octopus-shaped affair of chubby roots called a crown that stores enough starch through the winter to arrange the phallic send-up when winter starts to break. The effect is rather sexy, if you're the type to see things that way. Europeans of the Renaissance swore by it as an aphrodisiac and the church banned it from nunneries.

This particular orchid gets all its energy from fungi, sometimes from different kinds of fungi simultaneously. It never even begins to turn to the sun. No photosynthesis here. It relies utterly on its underground friends: the unseen, unsung fungi. Forgive me if this is a romantic vision. Orchids seem to have that effect on people. But since finding out that they are essentially reliant on fungi, I have a new perspective. They are not lone, rising, random gifts, like treasure. They are weak and desperate, and they are gamblers, hoping their luck holds and a good strong friend can be found close by to give them everything they lack. What do the fungi get out of the deal? The relationship of the orchid to the fungus is described as myco-heterotrophic, with the plant sometimes viewed as a sort of parasite, taking the carbon it needs and giving nothing back. Perhaps there’s more we need to learn here, to understand it fully. But, for now, I’ll anthropomorphise and romanticise it further by maintaining that a fungus can make a really good friend, especially if you’re a rare, weak seed with no energy of your own.

Ocean Acidification is sometimes referred to as Global Warming's Equally Evil Twin. The irony is intentional and fair enough as far as it goes... No single mechanism explains all the mass extinctions in the record and yet changes in ocean chemistry seem to be a pretty good predictor. Ocean Acidification played a role in at least 2 of the Big Five Extinctions: the End-Permian and the End-Triassic. And quite possibly it was a major factor in a third, the End-Cretaceous. ...Why is ocean acidification so dangerous? The question is tough to answer only because the list of reasons is so long. Depending on how tightly organisms are able to regulate their internal chemistry, acidification may affect such basic processes as metabolism, enzyme activity, and protein function. Because it will change the makeup of microbial communities, it will alter the availability of key nutrients, like iron and nitrogen. For similar reasons, it will change the amount of light that passes through the water, and for somewhat different reasons, it will alter the way sound propagates. (In general, acidification is expected to make the seas noisier.) It seems likely to promote the growth of toxic algae. It will impact photosynthesis—many plant species are apt to benefit from elevated CO2 levels—and it will alter the compounds formed by dissolved metals, in some cases in ways that could be poisonous. Of the myriad possible impacts, probably the most significant involves the group of creatures known as calcifiers. (The term calcifier applies to any organism that builds a shell or external skeleton or, in the case of plants, a kind of internal scaffolding out of the mineral calcium carbonate.)... Ocean acidification increases the cost of calcification by reducing the number of carbonate ions available to organisms that build shells or exoskeletons. Imagine trying to build a house while someone keeps stealing your bricks. The more acidified the water, the greater the energy that’s required to complete the necessary steps. At a certain point, the water becomes positively corrosive, and solid calcium carbonate begins to dissolve. This is why the limpets that wander too close to the vents at Castello Aragonese end up with holes in their shells. According to geologists who work in the area, the vents have been spewing carbon dioxide for at least several hundred years, maybe longer. Any mussel or barnacle or keel worm that can adapt to lower pH in a time frame of centuries presumably already would have done so. “You give them generations on generations to survive in these conditions, and yet they’re not there,” Hall-Spencer observed.

God said, 'Let there be light.' Here's a paraphrase: Let there be electromagnetic radiation with varying wavelengths traveling at 186,282 miles per second. Let there be radiowaves, microwaves, and X-rays. Let there be photosynthesis and fiber optics. Let there be LASIK surgery, satellite communication, and suntans. Oh, and let there be rainbows after rainstorms. 'Let there be light.' These are God's first recorded words. This is God's first recorded miracle. Light is the source of vision; without it we can't see a thing. Light is the key to technology; it's how we can talk to someone halfway around the world without so much as a second's delay because light can circle the globe seven and a half times a second. Light is the first link in the food chain; no photosynthesis equals no food. Light is the basis of health; the absence of light causes everything from vitamin D deficiency to depression. Light is the origin of energy; in Einstein's equation E = MC squared, energy (E) is defined as mass (M) times the speed of light (C) squared. The speed of light is the constant. And light is the measuring stick for space-time; a meter is defined as the distance traveled by light in a vacuum during a time interval of 1/299,792,458 of a second. Light is the alpha and omega of everything, and that includes you.

When Dennis McKenna drank ayahuasca , he had a vision in which he became “a sentient water molecule, percolating randomly through the soil, lost amid the tangle of the enormous root fibers of the Banisteriopsis World Tree.” I could feel the coolness, the dank dampness of the soil surrounding me. I felt suspended in an enormous underground cistern, a single drop among billions of drops … as if squeezed by the implacable force of irresistible osmotic pressures, I was rapidly translocated into the roots of the Banisteriopsis tree …” He was “carried through the articulating veins toward some unknown destination”. McKenna found himself within the extraordinary cellular mechanisms that turn light into “the molecular stuff of life”. Pulled on a kind of conveyor belt to the place where photosynthesis occurs. His consciousness exploded as he was “smited by the bolt of energy emitted by the phytic acid transducers and my poor water-molecule soul was split asunder”. As this vision ended, he found himself “embedded in the matrix” of the plant’s biochemical makeup. Suddenly he was suspended above the Amazon rainforest, looking over its vast expanse: “The vista stretching to the curved horizon was blue and green and bluish green, the vegetation below, threaded with shining rivers, looked like green mold covering an overgrown petri plate.” McKenna felt: “anger and rage toward my own rapacious, destructive species, scarcely aware of its own devastating power, a species that cares little about the swath of destruction it leaves in its wake as it thoughtlessly decimates ecosystems and burns thousands of acres of rainforest.” He wept. Suddenly a voice spoke to him: “You monkeys only think you’re running things. You don’t think we would really allow this to happen, do you?

For unknown ages after the explosive outpouring of matter and energy of the Big Bang, the Cosmos was without form. There were no galaxies, no planets, no life. Deep, impenetrable darkness was everywhere, hydrogen atoms in the void. Here and there, denser accumulations of gas were imperceptibly growing, globes of matter were condensing-hydrogen raindrops more massive than suns. Within these globes of gas was kindled the nuclear fire latent in matter. A first generation of stars was born, flooding the Cosmos with light. There were in those times, not yet any planets to receive the light, no living creatures to admire the radiance of the heavens. Deep in the stellar furnaces, the alchemy of nuclear fusion created heavy elements from the ashes of hydrogen burning, the atomic building blocks of future planets and lifeforms. Massive stars soon exhausted their stores of nuclear fuel. Rocked by colossal explosions, they returned most of their substance back into the thin gas from which they had once condensed. Here in the dark lush clouds between the stars, new raindrops made of many elements were forming, later generation of stars being born. Nearby, smaller raindrops grew, bodies far too little to ignite the nuclear fire, droplets in the interstellar mist on their way to form planets. Among them was a small world of stone and iron, the early Earth. Congealing and warming, the Earth released methane, ammonia, water and hydrogen gases that had been trapped within, forming the primitive atmosphere and the first oceans. Starlight from the Sun bathed and warmed the primeval Earth, drove storms, generated lightning and thunder. Volcanoes overflowed with lava. These processes disrupted molecules of the primitive atmosphere; the fragments fell back together into more and more complex forms, which dissolved into the early oceans. After a while the seas achieved the consistency of a warm, dilute soup. Molecules were organized, and complex chemical reactions driven, on the surface of clay. And one day a molecule arose that quite by accident was able to make crude copies of itself out of the other molecules in the broth. As time passed, more elaborate and more accurate self replicating molecules arose. Those combinations best suited to further replication were favored by the sieve of natural selection. Those that copied better produced more copies. And the primitive oceanic broth gradually grew thin as it was consumed by and transformed into complex condensations of self replicating organic molecules. Gradually, imperceptibly, life had begun. Single-celled plants evolved, and life began generating its own food. Photosynthesis transformed the atmosphere. Sex was invented. Once free living forms bonded together to make a complex cell with specialized functions. Chemical receptors evolved, and the Cosmos could taste and smell. One celled organisms evolved into multicellular colonies, elaborating their various parts into specialized organ systems. Eyes and ears evolved, and now the Cosmos could see and hear. Plants and animals discovered that land could support life. Organisms buzzed, crawled, scuttled, lumbered, glided, flapped, shimmied, climbed and soared. Colossal beasts thundered through steaming jungles. Small creatures emerged, born live instead of in hard-shelled containers, with a fluid like the early ocean coursing through their veins. They survived by swiftness and cunning. And then, only a moment ago, some small arboreal animals scampered down from the trees. They became upright and taught themselves the use of tools, domesticated other animals, plants and fire, and devised language. The ash of stellar alchemy was now emerging into consciousness. At an ever-accelerating pace, it invented writing, cities, art and science, and sent spaceships to the planets and the stars. These are some of the things that hydrogen atoms do, given fifteen billion years of cosmic evolution.

after centuries of observation scientists are still not exactly sure why the Amazon—unlike other forests, where leaves turn brown during the dry season—grows green and lush when the rain stops or how this reversed pattern of photosynthesis contributes to the broader seasonal distribution of water throughout the region.

Capitalism not only validates precapitalist notions of the domination of nature by man; it turns the plunder of nature into society’s law of life, To quibble with this kind of system about its values, to try to frighten it with visions about the consequences of growth is to quarrel with its very metabolism. One might more easily persuade a green plant to desist from photosynthesis than to ask the bourgeois economy to desist from capital accumulation. There is no one to talk to. Accumulation is determined not by the good or bad intentions of the individual bourgeois, but by the commodity relationship itself, by what Marx so aptly called the cellular unit of bourgeois economy.”26 —Murray Bookchin

By planting annuals and plowing and clearing so that the soil is open to the elements for much of the year, we’re managing for oxidation instead of photosynthesis, regardless of whether we realize it or not.

more leaves mean more photosynthesis. Robust leaves also mean more roots, which means more carbon streaming into the soil. Which means, at once, greater fertility and more carbon sequestered.

I observed that plants not only have a faculty to correct bad air in six to ten days, by growing in it...but that they perform this important office in a complete manner in a few hours; that this wonderful operation is by no means owing to the vegetation of the plant, but to the influence of light of the sun upon the plant.

are doing is “managing for” photosynthesis over oxidation in several ways: encouraging diversity, avoiding tillage, using cover crops, and generally improving the soil.

the President’s Science Advisory Committee, Panel on Environmental Pollution, published a report entitled “Restoring the Quality of Our Environment.”44 This report included a section on “climatic effects of pollution” that is notable for treating CO2 as a pollutant. It also includes an appendix on “Atmospheric Carbon Dioxide,” written by a committee chaired by Roger Revelle that also included Wallace Broecker, Joseph Smagorinsky, Harmon Craig, and Charles Keeling. This appendix discusses consequences of increases in atmospheric carbon dioxide such as the melting of the Antarctic ice cap, sea level rise, ocean warming, increasing acidity of fresh waters, and increased photosynthesis. The appendix notes that “[t]he climatic changes that may be produced by the increased CO2 content could be deleterious from the point of view of human beings.

Going down, light levels decrease so that at depths of more than a few hundred meters there is no photosynthesis, and, with a few remarkable exceptions, no primary productivity.19 Life in the dark ocean is largely dependent on what comes down from the surface waters. A few hundred meters is also the depth of the oxygen minimum layer, where dissolved oxygen is so scarce that animals with gills—that is most marine animals—are in a bind. Some, like the vampire squid, have evolved physiologies to deal with low oxygen levels, but all must use energy sparingly.

We accept gravity, aerodynamics, photosynthesis, thermodynamics, relativity, quantum mechanics, sexual reproduction, rain, thunder, earthquakes, volcanoes, and tidal waves, all based on science. But when it comes to the origin and nature of life itself we take leave of our senses for a trip into the supernatural. We literally lose our minds. Even

The scientific revolution proved that there are objective, discernible laws of physical  phenomena.  Take gravity, for instance.  You don't exactly have faith in the law of gravity so much as you just know that the law is the law.  Now we are learning that there are objective, discernible laws of non-physical phenomena. These two sets of laws are parallel.  Externally, the universe supports our physical survival.   Photosynthesis in plants and plankton in the ocean produce oxygen, which we need in order to breathe.  Internally the universe also supports our survival.  Emotionally and psychologically the internal equivalent to oxygen, what we need in order to survive, is love.  And human relationships exist to produce love.

The cold not only bears down on human bodies, but also bends sound. The forest sits under an inversion, chilled air pooling under a warmer cap. The colder air is like molasses for sound waves, slowing them as they pass, causing them to lag sound travelling in higher, warmer air. The difference in speed turns the temperature gradient into a sound lens. Waves curve down. Sound energy , instead of dissipating in a three dimensional dome, is forced to spread in two dimensions, spilling across the ground, focusing its vigor on the surface. What would have been muffled, distant sounds leap closer, magnified by the jeweler’s icy loupe. The aggressive whine of the snowmobile mingles with the churr and chip of red squirrels and chickadees. Here are modern and ancient sunlight, manifest in the boreal soundscape. Squirrels nipping the buds of fir trees, chickadee poking for hidden seeds and insects, all powered by last summer’s photosynthesis; diesel and gasoline, sunlight squeezed and fermented for tens or hundreds of millions of years, now finally freed in an exultant engine roar. Nuclear fusion pounds its energy into my eardrums, courtesy of life’s irrepressible urge to turn sunlight into song.

The Plant Kingdom exists to bring feeling into manifestation. On the plant level, feeling exists in a pure and passive form. The animal and human kingdoms manifest this more actively, more separately, but often with less beauty. Consciousness in plants is on a primal level of unity; therefore it is more psychic, telepathic. The earth, like a gigantic receptor or radio-station, inhales and exhales stellar and cosmic forces, the absorbed essence of which grows and unfolds as life. These forces are not all material, but include subtle energies of an occult or spiritual nature. Plants transmit the vital-emotional impulses, the life-force that is hidden in light. That is the gift, the grace, the power of plants. Plants exist to transmute light into life. Human beings exist to transmute life into consciousness, love. These three–light, life and love–are one, each an expression of the other, three dimensions of the same existence. Plants transmute light into life through photosynthesis. The human being transmutes life into consciousness through perception. The seers, through the yoga of perception, let plants speak to them. And the plants disclosed their secrets–many of which are far more subtle than a chemical analysis could uncover. Approaching plants in the same way today, not as objects for self-aggrandizement but as integral parts of our own unity, the true value of a plant will flourish for our unselfish use.

The hidden secret of fall: the leaves don’t actually “turn” colors. With the winter season coming, and the process of photosynthesis being without the key ingredients of warmth and sunshine, trees begin to break down chlorophyll. With the “green” gone, the other colors that have been there all along — the magical reds, golds, and oranges — begin to express themselves.

there is in fact no evidence that quantum mechanics is actually needed at all to account for consciousness—unlike other biological phenomena that we have considered in this book such as enzyme action or photosynthesis.

An oak tree can make 25 kilograms of glucose every single day. That’s the weight of a small child or a female golden retriever.

CARBON DIOXIDE IS necessary for photosynthesis, and thus for life on Earth.

Can the trees and flowers which we see all around us at all times have themselves formed such perfect systems as to bring about a phenomenon such as photosynthesis, some parts of which are still not fully understood, in their own bodies? Did plants choose to use carbon dioxide (CO2), of the gases in the air, to produce food? Did they themselves determine the amount of CO2 they would use? Could plants have designed those mechanisms which make up the root system and which enable them to take the materials necessary for photosynthesis from the soil? Did plants bring about a transport system where different types of tubes are used for transporting nutrients and water? As ever, defenders of the theory of evolution searching for an answer 16 The solar energy trapped by the chlorophyll in the leaf, carbon-dioxide in the air, and water in the plant go through various processes and are used to produce glucose and oxygen. These complex processes do not take place in a factory, but in special structures like those in the leaf in the picture, and which measure only one thousandth of a millimeter across. Sunlight Chlorophyll Glucose 6H2O Water Light Chlorophyll Carbon dioxide + Water Glucose + Oxygen 6CO2 Carbon dioxide 6O2 Oxygen C6 H12O 6 to the question of how plants emerged have resorted to "chance" as their only re m e d y. They have claimed that from one species of plant which came about by chance, an infinite variety of plants have emerged, again by chance, and that features such as smell, taste, and colour, particular to each species, again came about by chance. But they have been unable to give any scientific proof of these claims. Evolutionists explain moss turning into a strawberry plant, or a poplar, or a rose bush, by saying that conditions brought about by chance differentiated them. Whereas when just one plant cell is observed, a system so complex will be seen as could not have come about by minute changes over time. This complex system and other mechanisms in plants definitively disprove the coincidence scenarios put forward as evolutionist logic. In this situation just one result emerges.

Like other living cre a t u res, plants' structural characteristics are encoded in the DNA in their cells. In other words, how a plant will re p roduce, how it will breathe, how it will come by its nutrients, its colour, smell, taste, the amount of sugar in it, and other such information, is without exception to be found in all of that plant's cells. The cells in the roots of the plant possess the knowledge of how the leaves will carry out photosynthesis, and the cells in the leaves possess the knowledge of how the roots will take water from the soil. In short, there exist a code and a blueprint for the formation of a complete new plant in every extension that leaves a plant. All the features of the mother plant, based on its inbuilt genetic information, are to be found, complete, down to the last detail in every cell of every little part that splits off from it. So, in that case, how and by whom was the information that can form a complete new plant installed in every part of the plant? The probability of all the information being totally complete and the same inside every cell of a plant cannot be attributed to chance. Nor can it be attributed to the plant itself, or the minerals in the soil that carry out this process. These are all parts of the system which make up the plant. Just as it takes a factory engineer to program production line robots, since the robots cannot come by the instructions themselves, so there must be some being which gives to plants the necessary formula for growth and re p roduction, since the plants, like the robots, cannot acquire these by themselves. It is, of course God who implanted the necessary information in the plants' cells, as in all other living things in the world. It is He who without any doubt created everything in complete form, and who is aware of all creation. God draws attention to this truth in several holy verses: He created the seven heavens one above the other. You will find no flaw in the creation of the All-Merciful. Look again-do you see any gaps? Then look again and again. Your eyes will become dazzled and exhausted. (Surat al-Mulk: 3-4) Do you not see that God sends down water from the sky and then in the morning the earth is covered in green? God is All-Subtle, AllAware. (Surat al-Hajj: 63)

The rate of photosynthesis is the same for all the trees. The trees, it seems, are equalizing differences between the strong and the weak.

We know a great deal more than the Greeks did about the forces of life. But with all our knowledge, no one fully comprehends the miraculous process, known as photosynthesis, by which trees and other green plants use energy from the sun to transform elements into food for themselves at the same time that they release oxygen into the atmosphere. Photosynthesis makes life on Earth possible, and it is the most important function performed by green plants of all kinds.

Photosynthesis, the activity that ultimately makes all life possible, permits plants to trap energy from the sun and store it in the form of glucose, or sugar, for their growth. To make one molecule of sugar requires six molecules of water and six of carbon dioxide, taken from the air. When these are combined with the energy from the sun’s light, glucose is formed - to be stored within the plant - and oxygen and carbon dioxide are released into the air. As

The first forests about which anything is known were made up of the simplest kinds of plants, all of them spore-produced - horsetails, club mosses, and ferns. Relics of these primitive plants still survive today; everyone is familiar with the delicate, lacy ferns that are found in damp places in the woods, growing in the niches of rocks, spreading over the remains of fallen trees. But these plants are only miniature versions of their ancestors. During the Paleozoic era, between 280 and 425 million years ago, at about the time reptiles were evolving, ferns forty feet tall and club mosses five feet in diameter and 120 feet in height flourished in swampy lowlands between recurrent invasions of the sea. As these huge plants fell over into the water and slowly turned into peat, they retained their rich stores of solar energy, acquired through photosynthesis, which compacted first into lignite and then into coal by the growing weight of millions of years of deposits. Forest grew upon forest, and each in its turn was compressed into seams of coal beneath the surface of the ground. When we burn coal, we are using a fuel made from the sun’s energy and stored away in trees more than a quarter of a billion years ago.

Feel the warmth of the sun. Stretch out into this newly freed space. Be the bud. Understanding how to prune correctly involves consciously crossing the line between species and feeling what it’s like to embrace photosynthesis.

This is the place to dispel the "solar myth." The United States is a relatively sunlit nation of low population density, a particularly favorable place for solar energy. Yet even in the United States the numbers don't work out for it. In 1971 the average United States energy use was 0.3 watts per square meter. Staying with those units, the use rate will be 4.4 a century from now, even at the very modest growth rate of 2.5 percent per year overall (including population increase). Windpower, tidepower, photosynthesis, and hydroelectric power are all forms of solar energy. If

It could be expected that further investigations of Plastocyanin dimorphism would reveal new secrets related to photosynthesis – the most significant process, forming the biosphere as it appears, hence ensuring the existence of the animal world, as it also includes the highest form of the matter – the Homo sapiens.

While the "A" students are learning the details of photosynthesis, the ADHD kids are staring out the window and wondering if it still works on a cloudy day.

Teaching is like photosynthesis: making food from air and light. It tilts the prospects for life a little. For me, the best class sessions are right up there with lying in the sun, listening to bluegrass, or swimming in a mountain stream.

Kelp forests could be one way to expand the seas’ annual carbon absorption capacity. Their near-surface seaweeds capture CO2 through photosynthesis. One of the fastest-growing forms of plant life, kelp expands by up to two feet in length per day. As Charles Darwin commented upon his kelp encounters during his mid-nineteenth-century voyage on the HMS Beagle: “I can only compare these great aquatic forests with terrestrial ones. The number of living creatures of all orders, whose existence depends on kelp, is wonderful.

Planktonic algae produce 60 per cent of all Earth’s oxygen through photosynthesis and will be adversely affected by global warming and ocean acidification. Adult fish and even adult krill appear to tolerate changes in acidity reasonably well, but at larval levels marine animals can be sensitive to temperature, salinity, acidity and calcium saturation. If all these factors go haywire, there is likely to be a collapse of the species that forms the basis of the food chain.
