Insect Decline Quotes

When trees grow together, nutrients and water can be optimally divided among them all so that each tree can grow into the best tree it can be. If you "help" individual trees by getting rid of their supposed competition, the remaining trees are bereft. They send messages out to their neighbors in vain, because nothing remains but stumps. Every tree now muddles along on its own, giving rise to great differences in productivity. Some individuals photosynthesize like mad until sugar positively bubbles along their trunk. As a result, they are fit and grow better, but they aren't particularly long-lived. This is because a tree can be only as strong as the forest that surrounds it. And there are now a lot of losers in the forest. Weaker members, who would once have been supported by the stronger ones, suddenly fall behind. Whether the reason for their decline is their location and lack of nutrients, a passing malaise, or genetic makeup, they now fall prey to insects and fungi. But isn't that how evolution works? you ask. The survival of the fittest? Their well-being depends on their community, and when the supposedly feeble trees disappear, the others lose as well. When that happens, the forest is no longer a single closed unit. Hot sun and swirling winds can now penetrate to the forest floor and disrupt the moist, cool climate. Even strong trees get sick a lot over the course of their lives. When this happens, they depend on their weaker neighbors for support. If they are no longer there, then all it takes is what would once have been a harmless insect attack to seal the fate even of giants.

The human mind has evolved a defense against contamination by biological agents: the emotion of disgust.111 Ordinarily triggered by bodily secretions, animal parts, parasitic insects and worms, and vectors of disease, disgust impels people to eject the polluting substance and anything that looks like it or has been in contact with it. Disgust is easily moralized, defining a continuum in which one pole is identified with spirituality, purity, chastity, and cleansing and the other with animality, defilement, carnality, and contamination. 112 And so we see disgusting agents as not just physically repellent but also morally contemptible. Many metaphors in the English language for a treacherous person use a disease vector as their vehicle—a rat, a louse, a worm, a cockroach. The infamous 1990s term for forced displacement and genocide was ethnic cleansing.

Another misconception is that we don’t need to worry about the local supply of insects because insects are everywhere all the time. If this is true, where do all those insects come from and what do they eat? Do they just appear out of nowhere? Is Aristotle’s theory of spontaneous generation alive and well in our popular culture? I hope not. The fact is that all insects, every last one of them, are produced directly or indirectly by plants. They either eat some plant part, or they eat another animal that ate some plant part. What follows logically, then, is that when we reduce the amount of plants in any given place, we reduce the diversity and abundance of insects. Alarming headlines from around the world are reminding us of the critical linkage between plants and insects; we have removed more than half of the forests on earth and, not surprisingly, insect populations have declined globally by at least 45% since 1979

Despite the lack of head hair, tox screens of the pubic hairs had been extremely fruitful. Three of the five individuals, including the Asian, had been users of cocaine and Subutex, a heroin substitute. Analyzing cross sections of the pubes after cutting them into sections had shown that, for all three, narcotics use had at first strongly declined, then disappeared altogether in the weeks before death. Crushing the insect pupae hadn’t revealed anything: if the men had taken drugs in their final hours, traces of it would have been found in the keratin of the insects’ shells. Given this, the chief inspector had made a note to check releases from detox centers and prisons, as Subutex was a common drug on the inside. Perhaps they were dealing with ex-cons, dealers, or guys who’d gotten mixed up in something to do with drug trafficking. He couldn’t ignore any potential lead.

But isn’t that how evolution works? you ask. The survival of the fittest? Trees would just shake their heads—or rather their crowns. Their well-being depends on their community, and when the supposedly feeble trees disappear, the others lose as well. When that happens, the forest is no longer a single closed unit. Hot sun and swirling winds can now penetrate to the forest floor and disrupt the moist, cool climate. Even strong trees get sick a lot over the course of their lives.

Farmers had freed themselves in part from the blind natural forces of storm and insects only to become increasingly the victims of the equally blind forces of market fluctuations. (p. 14)

Inextricably linked to the climate emergency is a broader environmental crisis. A third of the Earth’s land is now acutely degraded, with fertile soil being lost at a rate of 24 billion tonnes a year through intensive farming.[19] Generating three centimetres of top soil takes 1,000 years, and, the UN said in 2014, if current rates of degradation continue all of the world's top soil could be gone within 60 years.[20] 95% of our food presently comes from the soil. Unless new approaches are adopted, the global amount of arable and productive land per person in 2050 will be only a quarter of the level in 1960. The equivalent of 30 football pitches of soil are being lost every minute. Heavy tilling, monocropping multiple harvests and abundant use of agrochemicals have increased yields at the expense of long-term sustainability. Agriculture is actually the number one reason for deforestation. In the past 20 years, agricultural production has increased threefold and the amount of irrigated land has doubled, often leading to land abandonment and desertification. Decreasing productivity has been observed, due to diminished fertility, on 20% of the world’s cropland, 16% of forest land, 19% of grassland, and 27% of rangeland. Furthermore, tropical forests have become a source rather than a sink of carbon.[21] Forest areas in South America, Africa and Asia – which have until recently played a crucial role in absorbing GHG – are now releasing 425 teragrams of carbon annually, more than all the traffic in the US. This is due to the thinning of tree density and culling of biodiversity, reducing biomass by up to 75%. Scientists combined 12 years of satellite data with field studies. They found a net carbon loss on every continent. Latin America – home to the world’s biggest forest, the Amazon, which is responsible for 20% of its oxygen – accounted for nearly 60% of the emissions, while 24% came from Africa and 16% from Asia. Every year about 18 million hectares of forest – an area the size of England and Wales – is felled. In just 40 years, possibly one billion hectares, the equivalent of Europe, has been torn down. Half the world’s rainforests have been razed in a century and they will vanish altogether at current rates within another. Earth’s “sixth mass extinction”[22] is well underway: up to 50% of all individual animals have been lost in recent decades and almost half of land mammals have lost 80% of their range in the last century. Vertebrate populations have fallen by an average of 60% since the 1970s, and in some countries there has been an even faster decline of insects – vital, of course, for aerating the soil, pollinating blossoms, and controlling insect and plant pests.
