to the nature, overpopulation is a big problem. more people, more pollution. and the big population is threatening the nature every second.
the rapid rise in world population is not creating problems only for the developing countries. the whole world faces the problem that raw materials are being used up at an increasing rate and food production can not keep up with the population increase. people in rich countries make the heaviest demands on the world's resources, its food, fuel and land, and cause the most pollution. a baby born in the united states will use in his lifetime 30 times more of the world's resources than a baby born in india. unleall the countries of the world take united action to deal with the population explosion there will be more and more people fighting for a share of leand leland, food and fuel, and the future will bring poverty, misery and war to us all.
