Buy custom Carbon Dioxide Sequestration essay
It is estimated by the U.S. Forest Service that all the forests in the United States, combined, sequestered approximately 309 million tons of carbon each year from 1952 - 1992, offsetting approximately 25 percent of human-caused emissions of carbon during that period. Over a 50-year lifespan, a tree generates almost $32,000 worth of oxygen, providing $62,000 worth of air pollution control. This tree would also be responsible for recycling $37,500 worth of water and controlling $31,000 worth of soil erosion.

When chimpanzees eat meat, they put large, tough leaves in their mouths. That helps them overachieve as meat eaters, as their teeth and jaws are poorly adapted for chewing meat. Mountain gorillas eat no meat at all. In the wild, great apes spend about half of their day chewing. Chimpanzees are the most carnivorous great ape, and although meat is the greatest treasure in chimpanzee societies, they often stop eating meat after chewing it for an hour or two and revert to fruit and other softer foods if they can get it. Chimpanzees when their staple, fruit, is scarce. Chimps have been seen killing monkeys, eating their organs, and then abandoning the carcasses to find more monkeys to kill. Organ meats and intestines are far easier to chew, and a poor meat chewer like a chimpanzee prefers soft meats. Just as chimpanzees prefer soft meats, predators will eat soft organs first and leave the tougher muscle for later, if they eat it at all. It depends on how plentiful the available flesh is, but the pattern across all predator groups is clear: eat the best, first, and leave the lesser quality foods to the end or let scavengers have them. It will always be a cost/benefit decision. All things being equal, the less time and energy needed to eat something, the sooner it will be eaten. If extra time and effort is needed to procure food, then the nutritional reward (primarily in energy) has to be exceptional to justify it. Evolutionary pressures have made animals into excellent accountants. The human sweet tooth is a relic of humanity’s fruit-eating ape heritage, and the desire for fatty foods reflects an adaptation to prefer that energy-richest of foods. Fat (made of hydrocarbons) is the ultimate energy windfall of all foods.
As the diagram depicts, the atom gets larger. When an electron moves into an orbit farther from the nucleus, the atom will vibrate more, like the way a car’s engine will vibrate more when it runs faster. Lateral movement (also called ) is called temperature. While finding an can be a frustrating experience, temperature is a measure of the kinetic energy (the energy of motion) in matter. As with the behavior of photons, at the atomic level the concept of temperature can break down, and classical behaviors emerge as groups of atoms lose their quantum properties. When one atom collides with another, there is a transfer of energy, as there is in any collision. The transferred energy can be stored by the electrons leaping into higher orbits. They can in turn release that energy in the form of photons and return to lower orbits.

Although Enlightenment philosophers acknowledged their debt to Newton (the world’s most towering intellectual of his time and one of history’s greatest scientists and mathematicians), he saw nothing improper with the slave trade and in 1720. When machines began reproducing human labor, the abolition of slavery also began, as it made unskilled labor uneconomical. Slavery, particularly the genocidal forms inflicted by Europe, were viable only for situations in which little professional skill was needed. Slavery worked best in mine and plantation work that used illiterate and often-expendable people. What became the USA was unique in the European age of slavery, in that tobacco operations, unlike sugar plantations, had more seasonal labor demands. Moreover, the environment of southeast North America was conducive to long-lived and fertile slaves, so that they could reproduce. Consequently, what became the USA was a , with its large slave population largely bred, not captured. People born into slavery are easier to keep enslaved than those born free, but they had to be kept illiterate and at low skill levels, or else they might desire freedom and obtain it. Late in the American era of slavery, some slaves were taught to read, but generally only one book, which justified slavery: the Bible. All the way to , apologists for slavery used Biblical passages to justify it. Many also justified antebellum slavery with economic arguments, stating that people took better care of something they owned rather than something they rented.

I know of no more informative contrast between industrial and preindustrial economies than comparing the USA’s North and South on the eve of its Civil War. The North had a vibrant, industrializing economy that quickly became history’s greatest, with its labor nominally free, and the South had a relatively moribund economy based on slave labor. The North used its industrial capacity to grind down the South in a war of attrition, just as . Superior industrial capacity, which is rooted in energy supplies, has won all major wars during the past two centuries. World War I ended when the , and much of the war was devoted to cutting off the other belligerents’ oil supplies. When Germany surrendered, it had one day’s worth of fuel. Japan attacked Pearl Harbor in 1941 only after the , and Germany lost World War II after its , and the Nazis simply ran out of fuel. Cutting off access to hydrocarbons, oil in particular, was the industrial equivalent of starving out the enemy in a siege, or how continually tried to cut off the other's access to wood. Oil has been humanity’s , and explains imperial meddling and warfare in the Middle East. All other factors are irrelevant or of extremely minor importance and are often promoted in an attempt to deceive uninformed observers such as the American public; proximate causes, if not entirely fictional to begin with, in those delusion-inducing analyses.
