Impact on the Environment

Abstract

Overpopulation has recognized as a global environmental problem since few decades, as it has caused a number of adverse effects on environment. Modern medical facilities and illiteracy in some interior regions of developing countries are the major reasons for development of this inverted pyramid demographic structure. Overpopulation has resulted in a series of catastrophic consequences by causing increased pressure on existing natural resources. Deforestation, effect on welfare, climate change, decline in biocapacity, urban sprawl, food security, increase in energy demand and effect on marine ecosystem are amongst most severe impacts of overpopulation. Concrete steps need to be taken on national and international level to combat the adverse effects of overpopulation, so that sustainability of natural resources can be ensured for future generations.
