Environmental issues: Overpopulation

              Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth. Overpopulation is caused by number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are few of the causes which results in overpopulation. It is possible for a sparsely populated area to become densely populated if it is not able to sustain life.


1. Overpopulation 'is main threat to planet'

     Climate change and global pollution cannot be adequately tackled without addressing the neglected issue of the world's booming population, according to scientists.

2. Effects of Overpopulation on the Environment

     6.5 billion…This is not a whole lot of bacteria, but when it comes to humans, it is a very formidable number. The human population has been increasing at an extremely high rate in the last century and unfortunately, not much has been done to slow down this process. Undoubtedly, overpopulation is a global issue. It is global because it pertains to all of humanity, but global also means that it affects the whole world, i.e. the environment. Almost all human activities impact negatively the environment in one form or another, and as human population expands, the damaging effects on the environment multiply

3. Overpopulation Negatively Affects Everything From Climate Change To Health Care

     In 1992, 68 percent of Americans believed population growth to be a pressing problem, according to public opinion polls from that year. In 2000, that number had declined to just eight percent of Americans and, most telling of all, the topic does not even appear in the most recent polls. Now a review of nearly 200 research articles reveals how population growth is being downplayed and trivialized by scientists despite its fundamental and negative role in the areas of employment, public debt, human welfare, extinction of species, and climate change. “More than one billion people live in extreme poverty and hunger, and ecosystems are losing species at rates only seen in previous mass extinction events,” wrote Camilo Mora, assistant professor of Geography in the College of Social Sciences at University of Hawaii at Manoa. “The issue of population growth has been downplayed and trivialized among scientific fields, which may in part account for the reduced public interest in the issue and in turn the limited will for policy action.” His sobering review appears in Ecology and Society.

4. Population and the Environment: The Global Challenge

     As the century begins, natural resources are under increasing pressure, threatening public health and development. Water shortages, soil exhaustion, loss of forests, air and water pollution, and degradation of coastlines afflict many areas. As the world’s population grows, improving living standards without destroying the environment is a global challenge.
