A careful estimate as of 2013 determined that humanity has reduced Earth’s plant-based biomass by more than a third since the beginnings of agriculture. Humanity certainly could not have industrialized by using wood. Arguments making the case that deforestation was not why coal was adopted in England are shaky and also irrelevant to the fact that England could not have industrialized with wood. Iron operations regularly shut down during England’s early industrial history due to wood shortages. The economics of coal were evident to even imperial Romans, but nobody would use coal if they could avoid it. Some until the late 19th century. But using sunlight energy captured during the tree’s life could not compete for long with mining ancient sunlight trapped in coal that was collected over tens of millions of years, even if nobody initially knew how coal was formed. Even today, the British Isles’ grassy hills provide austere evidence of the rampant deforestation that those lands have yet to recover from. That the British Isles have any woods at all is a testament to using fossil fuels to power the Industrial Revolution.

It will also provide an example of critical thinking applied to my current working environment.

As Adam Smith’s invisible hand, fear, became an of classical economics, neoclassical economists greed in their curves. Greed and fear are thereby foundational principles in today’s economic theory, and as a salubrious and critical aspect of capitalism. How can an ideology that elevates, even celebrates, greed and fear be considered beneficial? The obsession with prices and money has also promoted an egocentric view of economic reality. Whenever people think of economics today, they generally only think in terms of money, as that is the medium of exchange by which individuals currently acquire the food, goods, and services that make their modern lives possible. Consequently, the real economy, which runs on matter and energy, not money, becomes demoted and even ignored while the magic of markets and money are worshipped. The financial economy is not real, but is an elaborate accounting fiction subject to . Theorists such as Marx put money in its proper place, as only accounting. Money-based economics is egocentric, in which the focus is on money and greed and everybody’s primary question is “What is in it for me?” That view is also disconnected from the real world.

The modern use of is little more than pumping electrons to power electrical equipment, in the same basic fashion that running water was used to run . The electron flow, like running water, is not the ultimate source of energy, but is just an energy flow that humans harnessed, although humans the electron flow, unlike the . With electricity, the first major applications had . But coal-fired electric generators quickly became the standard, for the , and coal power today provides . Electrons pumped across copper wires became a major innovation that led to modern homes and cities. Before electricity was used to transmit energy, power was only available at the site where usable energy was produced. Watermills, windmills, and heat engines transmitted pre-electrical energy via gears, straps, and pulleys, which were cumbersome and dangerous. With the , factories became far more versatile and humane, and as cities and homes were electrified, they were radically transformed. The USA led the world in introducing electrical appliances to homes; refrigerators, thermostatically controlled central heating and air conditioning, vacuum cleaners, washing machines, dryers, dish washers, radios, televisions, and computers, to name a few innovations, made the early 21st century’s home virtually unrecognizable to a home-dweller during the USA’s Civil War. Electricity also powers the process used today to , and modern equipment of all kinds would simply be infeasible without electricity.

I will provide an example of a personal experience when critical thinking had to be used.

An important evolutionary principle is organisms' developing a new feature for one purpose and then using that feature for other purposes as the opportunity arose. As complex life evolved in the newly oxygenated seafloors, several immediate survival needs had to be addressed. To revisit the , if an oxygen-dependent animal did not have access to oxygen, it meant immediate death. Obtaining oxygen would have been the salient requirement for early complex life that adopted aerobic respiration , which is how nearly all animals today respire. While animals in low-oxygen environments have adapted to other ways of respiring (or perhaps in the first place), they are all sluggish creatures and would have quickly lost in the coming arms race. , which is a critical connective tissue in animals, requires oxygen for its synthesis, and was one of numerous oxygen-dependencies that animals quickly adopted during the Cambrian Explosion.

Eyes began with that captured photons that through chemical cycles in a new kind of specialized cell: the nerve cell. Neurons are energy hogs and “high-tension electric lines” in animals. Human brain tissue uses ten times the energy that non-organ tissues elsewhere in the body do. The first eyes probably only detected light, and perhaps even infrared light, so that from life-giving/destroying volcanic vents, for instance. Hydrothermal vent shrimp today , which can be likened to naked retinas. The development of an eye with a lens was not a great evolutionary leap from rudimentary eyes, and a recent calculation shows how eyes with lenses could have developed from scratch in about a half-million years of evolution. may have had the first precursors to eyes. Once the eye evolved, its benefit was overwhelmingly obvious, and virtually all animals that live where vision would help them have eyes. Animals that adopted subterranean existences . It is thought today that the development of eyes was a key innovation in the arms race that would soon characterize the eon of animals, and might have even triggered it. The gene is common to all animals with eyes. As , that gene supports the widely accepted idea that . The purpose of all senses is to detect environmental information, which is in turn processed by the brain. Even brainless plants can detect light and modify their behavior, such as .

Critical Period Hypothesis - Quora

There was a “” in the early Triassic, and depending on the framework and which scientist is asked, it took Earth’s ecosystems (when the environment recovered enough to sustain normal ecosystems), (when terrestrial ecosystem diversity recovered), or (when marine ecosystem diversity recovered) to recover from the Permian extinction. On land, the forests slowly recovered, and dominated the early Triassic. dominated the Southern Hemisphere, and palm-tree-resembling and ginkgo trees (which first appeared in the late Permian, of which the living fossil is the only surviving member) also prospered. In the , on what became North America, Europe, and Siberia, conifer forests recovered and blanketed the land.

After the mid-Permian extinction, marine life recovered and there were many radiations to fill empty niches, but coral reefs did not recover. Between the two big extinction events, extinction levels were highly elevated, which suggests that some of those aforementioned dynamics were still wreaking havoc, with possible . Critics of extinction hypotheses often say: “Correlation is not necessarily causation.” While there can be great merit to that position, it seems to be overused by various critics. When the guns are as smoking as volcanic events were, and they often “correlate” with mass extinctions, they are increasingly hard to deny as being at least immediately causative.

For an example of how geography impacted early animal evolution, therapsids are thought to have evolved in non-tropical Permian climates. That non-tropical beginning influenced therapsid evolution and particularly strategies for regulating body temperature. Therapsids were rather stocky , which is . There is plenty of speculation and research on the issue of therapsid thermoregulation because mammals are the therapsid line’s last survivors. Diapsids, on the other hand, evolved in warmer climates, were relatively gracile, and had particularly long tails. That long tail was critical for the appearance of bipedal reptiles, as it shifted their center of gravity over their hips.
