As this happens, we need to take great caution in making sure we don't harm the environment. In particular, population density plays the most important role in shaping the socio-economic environment. Overpopulation of specific locations can also result from migration. Low per capita income For a balanced per capita income, the economic and population growth must go hand in hand. Clearly, initiatives to switch to clean energy sources such as solar, improve agricultural practices, better manage water resources and fully embrace the principles of the circular economy will help us mitigate the impact of population growth. Almost all human activities affect negatively the environment in one form or another, as human population will expand the damaging effects on the environment will multiply. Most fossil fuel consumption comes from developed countries. Human population growth and climate change have grown hand in hand as the use of fossil fuels has exploded to support industrialized societies. The growth of population tends to retard the per capita income in three ways: 200 years ago, humans, our pets, and livestock only made up 10-12% of the earth’s mammal population. History of the Population Argument. The causes of overpopulation are apparent but not easy to address. Another commentator expects 2/3 of the world's population to be living with water shortages by 2025, which he attributes to population growth. The population of the world is slowly increasing. Human population increase is related to all of these deforestation pressures. The ways in which populations are spread across Earth has an effect on the environment. However, other statistics prove otherwise. 1. Copyright © 2015 PublishYourArticles.Net, All rights reserved. What is more concern, the number of population rise will increase to such an extent in future that it will cause overall scarcity for resources. More: Environmental Degradation Facts Worldwide, there are more than 400 marine 'dead zones' caused by eutrophication, collectively covering an area six times the size of Switzerland. Therefore this paper will discuss these two theories for population growth and their effect on the resources and environment of the earth. This approach is characterized by reliance on mechanization, pesticides and chemical fertilizers. 10 Reasons for Restaurants to Go Organic (You'll Like Number 9), The Balance Small Business is part of the, Agriculture is responsible for about 80 percent of deforestation. Oddly enough, the overpopulation of an area can occur without a net gain of population. The effects of population growth are varied and vast. Effects of Population Growth on Environment This is not the latest jackpot prize, but 6.5 billion is a very formidable number. The effect of growing population will be an increased demand for resources and space. Examples include corrections when the rapid growth may actually supply a population that wouldn't have existed to contribute otherwise. Although fertility rates have declined in most areas of the world, population growth continues to be fueled by high levels of fertility, particularly in Asia and Africa. Its effects are felt on the natural environment also. Deforestation in turn leads to a reduced ability to capture CO2, thus exasperating the greenhouse gas problem. There is a long-standing dispute on the extent to which population growth causes environmental degradation. imae source: 200 years ago, humans, our pets, and livestock only made up 10-12% of the earth’s mammal population. Land transformations induced by the spatial expansion of agriculture are probably the major route by which population growth has affected features of the natural environment. As forests are cleared and burned, that CO2 is released into the atmosphere, accounting for an estimated 25 percent of total greenhouse gas production. For the sake of simplicity they are listed separately, but understand the connections between them are complicated, which makes them more challenging to manage.
