As the war continued, the Athenian hinterland was turned into a desert. Plato described the deforestation of , which remained barren until my lifetime, when the Greek government began to reforest it; many trees could only be planted by blasting holes in the limestone bedrock. When Attica's residents returned home after the Spartan occupation, they built their homes with a southern orientation to take advantage of sunlight, as wood was scarce. After five years of peace with Sparta subsequent to , Athens took to the offensive again and pretended to intervene in a war in Sicily to protect Ionian colonists, but they really did it to conquer Sicily and plunder its forests and other resources, and thereby build another naval fleet to conquer Sparta. The was a catastrophe for Athens, and it lost most of its navy. There were other setbacks and victories, but a starving and besieged Athens finally surrendered to the Spartans in 404 BCE. The environment around Athens could feed nothing but “bees,” and where wolves once abounded, not a rabbit could be found. As Athens slowly became the center of a wasteland, the changing perceptions could be seen in contemporary writing. When forests were plentiful in 700 BCE, Greek authors wrote of trees in pragmatic fashion or as impediments to progress. As the forests disappeared along with the ecosystems they supported, an ecological consciousness began to appear. Plato and Aristotle placed forests at the root of a civilization’s health, and . Conservation only became an idea when the environment had already been ruined by “progress." Numerous commentators of the day wrote about the connections between forests and a healthy water supply, and many clearly saw the relationship between deforestation, erosion, and desertification, including Plato. and his professional heir wrote about ecological ideas. Theophrastus could be considered the first ecological writer, and he had the beginnings of an ecosystems approach.

For all of their seeming cunning and behaviors right out of , rhesus monkeys cannot pass the ; they attack their images, as they see themselves as just another rival monkey. Chimpanzees, on the other hand, pass the mirror test, and the threshold of sentience, whatever sentience really is, may not be far removed from the ability to pass the mirror test, or perhaps humanity has not yet achieved it. , considered the most intelligent New World monkeys, have socially based learning, in which the young watch and imitate their elders. Different capuchin societies have different cultures and different tool-using behaviors reflected in different solutions to similar foraging problems. Capuchins, isolated from African and Asian monkeys for about 30 million years, have striking similarities to their Old World counterparts, with female-centric societies and lethal hierarchical politics. As with chimpanzees and humans, ganging up on lone victims is the preferred method, which increases the chance of success and reduces the risk to the murderers. Unlike rhesus monkeys, for instance, capuchin males can help with infant rearing, but they will also kill infants that they did not father, as rhesus, also do (that behavior has been observed in 50 primate species). Those comparisons provide evidence that simian social organization results from the connection between simian biology and environment; their societies formed to solve the problems of feeding, safety, and reproduction.

Although Enlightenment philosophers acknowledged their debt to Newton (the world’s most towering intellectual of his time and one of history’s greatest scientists and mathematicians), he saw nothing improper with the slave trade and in 1720. When machines began reproducing human labor, the abolition of slavery also began, as it made unskilled labor uneconomical. Slavery, particularly the genocidal forms inflicted by Europe, were viable only for situations in which little professional skill was needed. Slavery worked best in mine and plantation work that used illiterate and often-expendable people. What became the USA was unique in the European age of slavery, in that tobacco operations, unlike sugar plantations, had more seasonal labor demands. Moreover, the environment of southeast North America was conducive to long-lived and fertile slaves, so that they could reproduce. Consequently, what became the USA was a , with its large slave population largely bred, not captured. People born into slavery are easier to keep enslaved than those born free, but they had to be kept illiterate and at low skill levels, or else they might desire freedom and obtain it. Late in the American era of slavery, some slaves were taught to read, but generally only one book, which justified slavery: the Bible. All the way to , apologists for slavery used Biblical passages to justify it. Many also justified antebellum slavery with economic arguments, stating that people took better care of something they owned rather than something they rented.

Since the most dramatic instances of speciation seem to have happened in the aftermath of mass extinctions, this essay will survey extinction first. A corollary to is that if any critical nutrient falls low enough, the nutrient deficiency will not only limit growth, but the organism will be stressed. If the nutrient level falls far enough, the organism will die. A human can generally survive between one and two months without food, ten days without water, and about three minutes without oxygen. For nearly all animals, all the food and water in the world are meaningless without oxygen. Some microbes can switch between aerobic respiration and fermentation, depending on the environment (which might be a very old talent), but complex life generally does not have that ability; nearly all aerobic complex life is oxygen dependent. The only exceptions are marine life which has adapted to . Birds can go where mammals cannot, , for instance, or being , due to their . If oxygen levels rise or fall very fast, many organisms will not be able to adapt, and will die.
