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.

The Cambrian Explosion’s iconic animal was the . As a child, I read every paleontology text in my elementary school’s library, and I have fond memories of imagining trilobite lives. Was there love among the trilobites? Among the protists? The bacteria? To a scientist, those questions might be unanswerable and even meaningless, but a mystic might pursue them. I will not wax too mystically in this essay (I do it ), but that may well be the big question of life on Earth and . The nature of consciousness and love in the Cambrian, or the lack thereof, as much as it may always be a mystery, does not invalidate life’s arc through the evolutionary process; it only challenges materialism.
In the oceans, the Carboniferous is called the Golden Age of Sharks, and ray-finned fish arose to a ubiquity that they have yet to fully relinquish. Ray-finned fish probably prevailed because of their high energy efficiency. Their skeletons and scales were lighter than those of armored and lobe-finned fish, and their increasingly sophisticated and lightweight fins, their efficient tailfin method of propulsion, changes in their skulls, jaws, and new ways to use their lightweight and versatile equipment accompanied and probably led to the rise and subsequent success of ray-finned fish in the Carboniferous and afterward. , which are amoebic protists, rose to prominence for the first time in the Carboniferous. Reefs began to recover, although they did not recover to pre-Devonian conditions; those vast Devonian reefs have not been seen again. did not appear until the . Trilobites steadily declined and nautiloids familiar today, and straight shells became rare. The first , which were ancestral to squids and octopi, first appeared in the early Carboniferous, but some Devonian specimens might qualify. Ammonoids flourished once again, after barely surviving the Devonian Extinction. This essay is only focusing on certain prominent clades, and there are many and . The early Carboniferous, for example, is called the Golden Age of , which are a kind of , which is a phylum that includes starfish. The crinoids had their golden age when the fish that fed on them disappeared in the end-Devonian extinction. Earth’s ecosystems are vastly richer entities than this essay, or essay, can depict.

Perhaps the most damaging deficiency in FE efforts, after self-serving orientation, was that the participants and their supporters were scientifically illiterate and easily led astray by the latest spectacle. Scientific literacy can help prevent most such distractions. While writing this essay, I was not only bombarded with news of the latest FE and alternative energy aspirants' antics, but I had to continually field queries regarding whether Peak Oil and Global Warming were conspiratorial elite hoaxes (or figments of the hyperactive imaginations of environmentalists and other activists), for two examples that readily come to mind. Digesting this essay's material should have those questions answered as mere side-effects. Far from being a hoax or imaginary, Peak Oil was and , and it is all downhill from there, and conventional oil will be almost entirely depleted in my lifetime. , although both were heavily promoted in the USA in 2014. In every paleoclimate study that I have seen, so-called greenhouse gases have always been considered the primary determinant of Earth's surface temperature (after the Sun), and carbon dioxide is chief among them. The radiation-trapping properties of carbon dioxide are not controversial in the slightest among scientists, and after the Sun's influence (which is exceedingly stable), declining carbon dioxide levels are considered to be the conditions that have dominated Earth for the past 35 million years. Humanity's increasing the atmosphere's carbon dioxide content is influencing the cause of Icehouse Earth, and , and are merely proximate causes. Increasing carbon dioxide can turn the global climate from an to a Greenhouse Earth, and the last time that happened, Earth had its . But have purposefully confused the issues, and a scientifically illiterate public and have played along, partly because believing the disinformation seems to relieve us all of any responsibility for our actions. Although scientific literacy can help people become immune to the disinformation and confusion arising from many corners, and reading this essay's first half can help people develop their own defense from such distractions, my goals for this essay's first half are far greater than that.
In 508 BCE, Athens entered its classical period, which lasted for nearly two centuries. In those two centuries, so much was invented by Greek philosophers and proto-scientists that it has been studied by scholars for thousands of years. One provocative question that scholars have posed is why the Industrial Revolution did not begin with the Greeks. The answer seems to be along the lines of Classic Greeks not having the social organization or sufficient history of technological innovation before wars and environmental destruction ended the Greek experiment. The achievements of Greece over the millennium of their intellectual fecundity are far too many to explore in this essay, but briefly, the Greeks invented: , , , the , a monetized economy, thought, such as , while developing other branches to unprecedented sophistication, and , which included the idea that . Long after the Classic Greek period was over, Hellenic intellectuals and inventors kept making innovations that had major impacts on later civilizations, such as Heron of Alexandria (or some other Greeks) inventing the and .

Part of the hypothesis for skyrocketing oxygen levels during the late Proterozoic was that high carbon dioxide levels, combined with a continent that had been ground down by glaciers, and the resumption of the hydrological cycle, which would have vanished during the Snowball Earth events, would have created conditions of dramatically increased erosion, which would have buried carbon (the cap carbonates are part of that evidence) and thus helped oxygenate the atmosphere. Evidence for that increased erosion also came in the form of strontium isotope analysis. Two of strontium’s stable isotopes are . Earth’s mantle is enriched in strontium-86 while the crust is enriched in strontium-87, so basalts exposed to the ocean in the oceanic volcanic ridges are enriched in strontium-86 while continental rocks are enriched in strontium-87. If erosion is higher than normal, then ocean sediments will be enriched in strontium-87, which analysis of Ediacaran sediments confirmed. That evidence, combined with carbon isotope ratios, provides a strong indication of high erosion and high carbon burial, which would have increased atmospheric oxygen levels. There is other evidence of increasing atmospheric oxygen content during the late Proterozoic, such as an increase in rare earth elements in Ediacaran sediments. Although there is still plenty of controversy, today's consensus is that the Cryogenian is when , where they have largely stayed, although as this essay will later discuss, oxygen levels have varied widely since the late Proterozoic (from perhaps only a few percent to 35%).

Readers for the collective task that I have in mind need to become familiar with the scientific process, partly so they can develop a critical eye for the kinds of arguments and evidence that attend the pursuit of FE and other fringe science/technology efforts. For the remainder of this essay, I will attempt to refrain from referring to too many scientific papers and getting into too many details of the controversies. Following my references will help readers who want to go deeply into the issues, and many of them are as deep and controversial as the Snowball Earth hypothesis and aftermath has proven to be, or attempts to explain the . These are relatively new areas of scientific investigation, partly due to an improved scientific toolset and ingenious ways to use them. It is very possible that the controversies in those areas will diminish within the next generation as new hypotheses account for increasingly sophisticated data, and in the near future are nearly certain. But science is always subject to becoming dogmatic and hypotheses can prevail for reasons of wealth, power, rhetorical skill, and the like, not because they are valid. The history of science is plagued with that phenomenon, and probably will be as long as humanity lives in the era of scarcity.
