Will The World Starve Essays - Population, Environmental Issues

Will the World Starve? Looking out a window upon a barren desert, a dry wasteland unfolds as a carpet to nowhere. Abandoned cities dot the horizon, as the ruins speak volumes to the once populated extravagance of a country which lived on wealth and opportunity. The vision just described is not one out of a Hollywood movie script, but one that is not only possible but probable. Currently, the world population numbers over six billion, with China alone cradling over one-sixth of the world's total population. With the world population increasing at a rate of one hundred million a year, the numbers are expected to hit ten billion by the end of 2040. Most scientists agree that the maximum number of people that the earth can sustain is fifteen billion, leaving the earth in a quandary before the end of the twenty-first century when the total world population is expected to reach a staggering sixteen to eighteen billion. The consumption of the world's natural resources due to this exponential growth could result in worldwide famine, a complete breakdown in the world market, uncontrollable outbreaks of disease, and widespread crime and disorder. Currently, the ratio of land which can be used for agricultural endeavors is estimated to be one in nine acres. The world's produce producer is only a small sliver of a total land mass apple pie sliced into nine equal, yet tiny slices and as the amount of soil suitable for agriculture dwindles, the slice with which the world relies on continues to shrink. Considering the little amount of available farmland, it should be expected that there would be more of an effort to conserve this vital resource, but unfortunately the issue has not yet risen to a level of global importance. The amount of fertile topsoil is becoming more and more unusable for agriculture. Water, used for the irrigation of the world's life giving crops, contains naturally dissolved minerals and over time the minerals from the irrigated water supply collect in the topsoil. After many years of constantly farming a particular region, the soil begins to become less and less fertile. This process, known as salinization, has affected many of the farms around the world. Once this process is complete, the soil becomes totally useless for any kind of farming. Over long periods of time, salinization, combined with the erosion of the topsoil due to wind and rain, starts to cause the world's farmlands to exponentially dissipate. Ethiopia is a prime example of how salinization, combined with overgrazing and erosion, has affected every aspect of the economy. Food shortages, lack of domestic trade products, and low incomes for farmers and agricultural workers are all bi-products of a land ravaged by overuse and abuse. With the people scrambling to find a quick fix solution to this problem that has been building for decades, the economy along with the people's only domestic food source, is slipping further and further into a seemingly unrecoverable disaster. The earth's industry is expected to produce enough manufactured materials to support the world's current six billion people. The list of finished products includes food (from agriculture), clothes and all other luxuries which most of the world has become accustomed. If most scientists are correct, the maximum capacity of which the world can sustain is estimated to be fifteen billion people. Maximum capacity is described as the amount of people that can be sustained without causing a complete breakdown in society. Numerous scientists have speculated that many of the world's natural resources used to support current life such as clean water and air, gasoline, oil, and even coal will almost be completely depleted up by the end of the century. With decimated natural resources, a lack of topsoil, and a completely over-populated planet, anthropologists have agreed that the end of the century, if not before, will culminate in a complete breakdown of industry in the world market. With this extinction of resources looming, it is obvious that new methods of energy and topsoil conservation need to be discovered. Speculation has been made that it is too late to turn back the dependence which humans have developed for natural resources. How can anyone be expected to turn away from their gas-powered cars and their electric houses? If, however, the current rate of consumption continues, then there is no doubt what the future will hold. Since 1950 half of the world's trees have been cut down and every day six square acres of rain forest are lost to the hum of a
