Overpopulation has led to many negative environmental impacts in the developing world. Probably the most critical area in water use. Population have grown to exceed the amount of usable water for both agriculture and drinking. The lack of safe drinking water contributes to epidemic diseases and high child mortality rates. Many rivers are so heavily used for irrigation that they run dry before reaching their mouths, degrading or destroying fish habitat and downstream agriculture. Another major problem is deforestation, especially in the Amazon, where excess population causes people to chop down massive areas of rain forest to grow crops and raise animals. Because farmland cannot sustain rapidly expanding rural populations, there has been dramatic urbanization, with the rural poor moving to cities leading to the development of massive slums such as the favelas of Brazil and the notorious slums of Mumbai. Population pressures are also responsible for wars and civil unrest.
