The view of dinosaurian intelligence has also changed radically in the past generation, as evidence has been discovered that some dinosaurs were significantly (particularly the ), as well as evidence for , and . Dinosaurs had the first hands, even with . Recent work on encephalization suggests that animals were well on their way toward human-level encephalization hundreds of millions of years ago, and were prevented from attaining it far earlier, , due to the Permian extinction. The world might be populated with sentient, civilized, and even space-faring reptiles today if events had played out slightly differently, such as that asteroid missing Earth 66 mya (or technologically advanced dinosaurs preventing its impact).

From the Permian extinction’s devastation arose a reptilian sheep called . Fossil hunters of early Triassic sediments have been frustrated for many years, as nearly are , because it was about the Permian extinction’s only land animal survivor. There has been about why it survived when almost nothing else did. No single animal ever dominated Earth’s land masses as thoroughly as did during the early Triassic. was probably a burrower (many have likened to a pig because of that burrowing), which may have provided the shelter needed to survive the Permian holocaust. It may also have been a and could eat most surviving plants. But some think that its survival, when almost every other species died, was due to luck. Luck is a surprisingly common proposed explanation for evolutionary events and outcomes, and some creatures seemed to be in the right place at the right time while others were in the wrong place at the wrong time. The spread of was also aided by two other facts: the land masses , so could simply walk to dominance of Earth; and few predators capable of eating a survived. One (being semi-aquatic may have also helped species survive the Permian extinction), as did , but not much else did. was a , as were the dominant land animals before the Permian extinction.
appeared in the Mesozoic and required oxygen to form calcium carbonate. They became so abundant in the high oxygen of the late Cretaceous that the rain of their bodies on ocean floors gave the its name: chalk (the Latin name). Calcium carbonate, the primary constituent of limestone, comes in two forms: and . The magnesium content in the oceans, as well as the ocean temperature, determines which form of calcium carbonate will dominate. The also marked the end of a 100-million-year ice age and gave way to about 200 million years of hot times. During , Earth has . That pattern also seems . Hot seas are generally and cold seas are usually . Calcite seas create , which influence the biome that forms. The and periods had vast carbonate hardgrounds, which disappeared during the and returned in the Greenhouse Earth age of dinosaurs, becoming common in the Jurassic. Today’s Icehouse Earth has aragonite seas, so organisms that form calcium carbonate shells use aragonite, which is less stable than calcite and its formation is sensitive to temperature and acidity. Coral reefs, key phytoplankton (which help produce Earth’s oxygen), and shellfish use aragonite today to form their shells. There is already that acidification of the oceans due to humanity’s burning of fossil hydrocarbon deposits to power the industrial age is interfering with the ability of coral, carbonate-forming phytoplankton, and shellfish to form their shells. That is only one of the industrial age’s many deleterious ecosystem impacts. The current aragonite-formation situation is not a theoretical construct of fearful environmentalists, but is a .

I continued to and became my . My former partner is the Indiana Jones of the free energy field, but I eventually realized that while it was awe-inspiring to witness his efforts, one man with a whip and fedora cannot save humanity from itself. I eventually took a different path from both my partner and astronaut colleague, and one fruit of that direction is this essay. Not only was the public largely indifferent to what we were attempting, but those attracted to our efforts usually either came for the spectacle or were opportunists who betrayed us at the first opportunity. As we weathered attacks from the power structures, such treacherous opportunities abounded. I witnessed dozens of attempts by my partner’s associates to steal his companies from him (, , , ), and my astronaut colleague was twice ejected from organizations that he founded, by the very people that he invited to help him. During my radicalizing years with my partner, I learned that , and it is the primary reason why humanity is in this predicament. The antics of the global elites are of minor importance; the enemy is us.

This essay is intended to draw a comprehensive picture of life on Earth, the human journey, and energy's role. The references that support this essay are usually to works written for non-scientists or those of modest academic achievement so that non-scientists can study the same works without needing specialized scientific training. I am trying to in a tiny fraction of the global population. . My hope is that the energy issue can become that tiny fraction's focus. Properly educated, that group might be able to help catalyze an energy effort that can overcome the obstacles. That envisioned group may help humanity in many ways, but my primary goal is manifesting those technologies in the public sphere in a way that nobody risks life or livelihood. I have seen too many wrecked and prematurely ended lives (, ) and plan to avoid those fates, for both myself and the group’s members.
