, who had a scientific career at General Electric, also believed that the energy industry would welcome his solid-state FE device. He , expecting a tickertape parade. The opposite happened as shadowy interests destroyed his business deals, in a situation . Sparky did not take the hint and kept trying, which led to death threats. After their final threats, Sparky fled into hiding, where , and Sparky died the next week of a “heart attack.” Dying that way who played near Sparky’s level, and , and the event shortened his life. Dennis, Sparky, and many others like them lost their naïveté the hard way, but the field has been filled with newcomers who deny the reality of organized suppression as they charge forward with visions of riches and fame. It is perhaps the most common level of awareness where FE newcomers will be found. Most never develop anything worth suppressing so will never know any differently, and will enter and leave the field with that beginner's level of awareness intact. However, with enough people trying and either living to tell the tale, or others chronicling their dire fates, which , and the Internet spreading information like never before, few FE newcomers have much excuse for being unaware of the fates of their professional ancestors. The Internet is like the , or the , ratcheted up by a few orders of magnitude, and my website, this essay, and my comprise my attempt to take advantage of its potential.

The end-Permian extinction correlated rather precisely with the eruption of the , which continued for a million years and spewed millions of cubic kilometers of basalt. The end-Permian extinction was the final blow for many ancient organisms. My beloved made their final exit from Earth during the end-Permian extinction, as did tabulate and rugose corals, , and the last freshwater . Articulate brachiopods completely vanished from the fossil record, but reappeared in the Triassic via , but brachiopods never recovered their former abundance and have lived a marginal existence ever since. and disappeared along with the reefs, while complex foraminiferans and also vanished, and all of them staged comebacks in the Triassic via ghost ancestors. Bivalves suffered relatively modestly (“only” about 60% of bivalve genera went extinct) and quickly recovered, fish were barely affected, and gastropods were devastated but quickly recovered. Ammonoids went through their typical boom-and-bust pattern during the Permian extinctions, while nautiloids kept dwindling but scraped by in their deep-water exile. In the final tally, more than 95% of all marine species went extinct. Not only was the death toll tremendous, but the from before that the Permian extinction marks the end of an era, which began with the Cambrian Explosion. The ended with the Permian extinction and the began.

Entropy is another important concept for this essay. Entropy is, in its essence, the tendency of hot things to cool off. The concept is now introduced to students as . Even though science , it can measure its effect. At the molecular level, entropy is the tendency of mass to become disordered over time, as the random motion of molecules spreads in collisions with other molecules, until the interacting molecules have the same . Life had to overcome entropy in order to exist, as it brought order out of disorder and maintained it while alive, and it takes energy to do that. The prevailing theory is that net entropy can only increase, and life has to create more entropy in its surroundings so that it can reduce entropy internally and produce and maintain the order that sustains itself. Life is called a negentropic phenomenon, in which it uses energy to reverse entropy to make the order of its organism’s structures, and it is continually using energy to reverse the natural entropy that is called decay.

Plants continued to evolve, adding oxygen to the atmosphere. They were abie to develop . Plants that produce fruits are called Spermatophyta. The most primitive ones don't have the seeds confined inside the and are known as Gymnosperms or " plants without flowers". The most highly evolved plants are called Angiosperms or " flowering plants". They produce seeds shut in fruits.

Plants have contributed and go on contributing to create the right conditions for life on Earth to be possible. Thanks to the living creatures that produce oxygen, living organisms can breathe. Also, these organism have also contributed to the formation of ozone, a gas produced by the action of sunlight on oxygen. Ozone creates a layer in the admosphere that protects us from harmful ultraviolet rays.

Another consequence of photosynthesis is the reduction of carbon dioxide, a gas that, by accumulating in the atmosphere, retains heat from the sun's rays and causes the fatal famous "greenhouse effect".

Plants have protected us for many millennia from "global warming" by absorbing the excess of carbon dioxide. Unfortunately, the burning of fossil fuels has increased its levels in such a way that plants themselves, progressively decreasing in number and variety, are not longer able to solve the problem of a planet which is getting increasingly hot.

Water provides buoyancy for aquatic organisms, e.g whales

Life on earth depends on plants. Humans, like other animals, can not feed themselves. Directly or indirectly, what they eat comes from plants.

Plants are important for having changed the composition of the Earth's atmosphere. Plants are also important because they are able to develop their own organic matter (sugars, fats, etc.) from simple inorganic elements (minerals and water), something that can only be achieved by plants and other lower organisms (algae and some bacteria). These piants and organisms are called primary producers.

All the other living organisms on earth feed on organic matter produced by plants and some lower organisms, First, the primary consumers or herbivores that incorporate food in their bodies produced by plants. For example, a rabbit eats the carrot or a crab larvae consume the tiny plant organisms that float on water. Many living creatures feed on hervivores. they are called carnivores or consumers.

Some carnivores (Primary consumers) are eaten by other carnivores (Secondary consumers) which can be eaten by another ones (Tertiary consumers). A wild rabbit in the country can be eaten by a fox and a wolf or a dog can also eat the fox or even the rabbit. At the sea water, the larvae of crabs are eaten by sardines that are eaten by tuna.

Chemistry for Biologists: Water and living organisms

If you live in Florida or on the French Riviera you might not wake up everyday wondering how melting snow contributes to the water cycle. But, in the world-wide scheme of the water cycle, runoff from snowmelt is a major component of the global movement of water. In the colder climates much of the springtime and in rivers is attributable to melting snow and ice. The effect of snowmelt on potential flooding, mainly during the spring, is something that causes concern for many people around the world. Besides flooding, rapid snowmelt can trigger landslides and debris flows.
