rbed their population growths. Most of Europe has either a growth of 0% or it is in the negative numbers. America is also trying to curb it population growth of 2%. Developing nations are where the population controls are needed. Even among the developing nations there is a divide. One group, exemplified by the Eastern Asian countries have made efforts to keep families small and in return see increased quality of life and falling fertility. The other group of developing nations, mostly comprised of the continent of Africa and the Indian subcontinent, have not addressed the issue of population control. It is these countries that will and in some cases are seeing the effects of overpopulation directly. The indirect effect of these countries, such as migration and social problems will become the problems of countries in Europe and the United States.The main determinant of the Earths carrying capacity can be packaged under the term of sustainable resources. Sustainable resources are resources need for life that are being replenished at the same rate or at a higher rate than it is being used. Resources such a freshwater, cropland and grain, air, habitable land, and forests are resources vital for life. Once abundant and seemingly endless, they have become valuable commodities and are no longer sustainable resources.One of the main criteria for life is the presence of water. One may say that water has an endless supply and that it provides no worries. This assumption however is wrong. We has human use water in many forms and now we are looking at depleting our supply. Human also limit themselves in the fact that we rely primarily on freshwater for our various activities. Aquifers in India are a prime example of how over population is making resources unsustainable. As population grows the need for water increases. Not only drinking water is needed but also a great portion of Indias farmland is irrigated and so as population increase...
