Overpopulation and Environmental Degradation


At the time of the agricultural revolution, nearly ten thousand years ago, the population of the globe was no more than ten million. Today the world population is estimated at over six billion. In the last hundred years the population has more than tripled. With the population rising at an enormous rate of 1.7 million a week, the world as a whole is being drained of its resources. (Southwick, 1996) Different theories have prevailed on what will occur as the population continues to explode ranging from the Malthusian apocalypse to absolutely no effects at all. Over the last two centuries as agricultural and technological advancements came about, the planet's overall carrying capacity increased dramatically. It is estimated that the world could support over twenty times its current population living at 120 per square meter in 2000-story buildings. (Dolan, 1974) Overpopulation not only adversely affects the "environment," or nature, but also has a large impact on human societies today.

Environmental degradation and population growth go hand in hand. As more people enter the world, there is a greater need for space, furthering damage to our surroundings. As populations grew in response to the agricultural revolution of ancient times more land was required for cultivation to feed the rising populations. Forests were cleared, waterways were diverted, and the soil exhausted, all a result of the expanding populace. Even today in parts of the world, especially third world countries, land is being cleared by slash and burn methods for grazing land and urban development. Whole species of organisms in areas like the Amazon rainforest have most likely been lost due to this method of deforestatio...

...devastating effects, notably poverty, disease, and famine, on poorer countries that cannot handle the needed health care for their mounting populations.

Rapid growth of the human population is occurring today with three births for each death. (Southwick, 1996) The modern countries of today cannot turn their back on the third world as everything that occurs on this planet is related. These issues are becoming more and more difficult to solve and are escalating each day. More time and effort needs to be done to look at the root of these issues if there is any hope to fix them.

Overpopulation, Industrialization, and the Degradation of the Environment - Overpopulation, Industrialization, and the Degradation of the Environment The overall growth of the human population in the last 2000 years has been a J-shaped growth. This can also be expressed as an exponential growth. A big question that can only be answered in time is how this population growth will slow down or stop. The planet can only handle so many humans before the effects of overpopulation send the environment into an unrecoverable tailspin of degradation. So the question is will the overall maximum human population be reached in a gradual manner with a trend resulting in an S-shaped population growth, or do we as humans need to experience some kind of catastrophic event that wi...   [tags: Environment Environmental Pollution Preservation]
