Trees use light to make food through photosynthesis

Canals were competitive with railroads, sailing ships were competitive with steamboats, and watermills were competitive with steam-powered mills until around 1850. It for coal-powered steam to prevail against wind and water power. Water and wind power were not only geographically restricted, but they were also dependent on the weather. Calm air (and storms) and droughts (and floods) were the bane of wind and water power. Coal did not have those restrictions. American towns were built on hillsides above watermills to house the workforce. As coal-power made its ascendance, those mills and towns were abandoned. The pollution of industrial America’s cities could rival London’s. A visitor to Pittsburgh in 1841 described approaching the city as entering a dark cloud of coal smoke; the peoples and buildings inside it were blackened like some vision from hell. Far from an indictment, however, the visitor happily saw it as “progress” that would soon arrive at his home town of Cincinnati. The rivers of the Eastern Woodlands ran blue and clear before Europeans arrived. When I lived in Ohio, the Ohio River at Cincinnati in the 1990s had brown, stinking waters that nobody in their right minds would swim in. The Cuyahoga River that flows through Cleveland , and the 1969 fire finally led to environmental legislation that began to clean up the USA’s lakes, rivers, and air. The in the 1980s rivaled .

Do all plants use photosynthesis

When birds began to fly, their energy requirements skyrocketed. Today’s bats, for instance, and , just as birds live far longer than similarly sized mammals. Mammalian life-expectancy in which size, metabolism, and longevity are all closely related. The general rule is that all mammals have about the same number of heartbeats in a lifetime. A mouse’s heart beats about 20 times as fast as an elephant’s, and an elephant lives about 20 times as long as a mouse. Larger bodies mean slower metabolisms, or less energy burned per unit of time per cell. Birds have the same kind of size/metabolism/life-expectancy curve, but it sits on a higher level than mammals'. A pigeon lives for about 35 years, or 10 times as long as a similarly sized rat. On average, birds live three-to-four times as long as similarly sized mammals.

Lichens typically do use photosynthesis

Because of the stupendous energy demands of flight, birds not only have the superior air sac system for breathing, but their , the cell’s energy-generation centers, are far more efficient than mammalian mitochondria. Parrots in captivity can , scientists have noted an , and scientists may discover that wild albatrosses live to be 100 or more, when their tagging programs get that old. The may explain bird longevity, as the efficient mitochondria of birds . The theory is controversial and will be for many years, but I think that an engine analogy can help. A bird is a piece of high-performance biological technology, and when operating at peak output it puts all land-bound animals to shame. But a bird’s metabolism is usually in its slack state, only maximized during flight. Simply put, a bird has a great energy capacity that is rarely used to its fullest. It is like a high-performance engine that rarely runs near its . Such engines will last far longer than those regularly running near redline. High-performance technology that usually “loafs” in its slack state and is rarely taxed is expensive and long-lasting. The increased investment in superior technology allows for high performance and long life. High-quality technology is more economical in the long run, if the initial investment can be afforded.

Plants are autotrophic and make their own food via photosynthesis

Photosynthesis is a natural process by which trees and plants use energy from the sun and carbon dioxide from the air to make the food they need to live and grow. By storing carbon above and below the ground, the trees and plants in forests contribute to the production of oxygen as a byproduct of photosynthesis.

So, either the plant usesits own stored sugars, or some animal (or decomposer) consumes the plant, and uses thestored sugars.

Female simians usually stay within their society of origin, while males leave. That is how simians prevented , but that pattern is reversed in chimpanzee and gorilla societies, in which females usually leave. Sexual coercion of females is common behavior among simians. and are among the few simians that overcame it, and it seems to have been due to ecological dynamics. Humans have partially discarded that behavior during the industrial age. Those are obviously highly charged areas of behavioral research, and is a scientific discipline. A is arguably the of science, and behavioral sciences have often been plagued with a lack of them, going back to , which has caused some to say that psychology is not really a science. This essay will soon sail into some of those murky waters.

Saturated conditions from spring runoff or flooding doesnot hurt most trees because they are not actively growing.

the plant doesn't use all of it

One major problem with making a positive impact on a global level, ultra-elite machinations aside, is that almost nobody focuses on what is important, which I hope to help remedy with this essay. Almost everybody hacks at branches if they hack at all. Conspiracists tend to obsess on elite machinations, which is an exercise of dubious benefit to begin with, but they often become paranoid and also confuse retail elites or other interests with the GCs. Bill Gates and David Rockefeller are probably not members of the GCs’ organization. Also, I learned that ultra-elites can only play their games with the responsibility that almost all people have abdicated as they play the victim. The GCs are only a symptom of our malaise, not a cause. They cannot be beaten at their game, and it is counterproductive and can even be suicidal to try. Making them obsolete is probably the best that we can do. While conspiracists often fixate on ultra-elite machinations, intellectuals, academics, and scientists tend to deny that such activities even exist or are meaningful. It took me many years to understand their resistance to even acknowledging ultra-elite existence, and I think it partly relates to the mainstream scientific worldview that . They have an ideological aversion to the notion that anybody manipulates events on a global scale, and believe that what seems conspiratorial is only anarchic elites competing with each other, which is like Darwin’s view of evolution. They believe that conspiracists see a pattern where none exists, or that the situation can be explained without invoking conscious intent, like materialistic hypotheses of how the universe operates. Radical leftists have to the of such elites; such an idea scares them. Neither obsession nor denial helps people attain productive understandings of the issue. Conspiracists and structuralists are united in thinking like victims, and that, as I see it, . Until they relinquish thinking like a victim, they will not constructively engage the critical issues that humanity faces, and energy ranks above all else. Victims are reactive instead of proactive, and only and resulting action has a prayer of working, in my opinion.
