We are in grave , grave trouble. There are 3,6 billion human beings on the face of the Earth.According to our best estimates, there are somewhere between three and seven times more people than this planet can possibly maintain over a long period of time. ...Non-renewable resources are being exhausted at a horrendous rate, and we are destroying the capability of the planetary ecosystem to renew the supply of renewable resources. (Hinrichs,8)
The worse however is yet to come.here are some numerical data that are present in John Laffin's The Hunger to Come: "About 2050 the population will be 15.000 million, a century later 82.000 million and by 2350 a frightening 440.000 million will be reached”(47).We need to realize the necessity of a population plan which will make us more optimistic as far as our future is concerned.This plan must be based on the fact that the control of the rapid population growth is necessary globally; otherwise, earth's environment will be put into greater danger,the overexploitation of natural resources will continue and poverty will rise in most of the world's countries.
In order to understand why rapid population growth is a threat and why we need to control it we must examine the problems which population expansion generates.
First, population growth has serious effects on the environment. As we all know we consume materials and energy from earth and then return heat and wastes to earth. It is only logical to say that there is a limit at which these wastes can come to our planet without having serious effect on humans. According to Noel Hinrichs the basic reason for the decrease in the quality of the environment is the absence of control over technology, land-use and especially over pollution. Nevertheless, due to the fact that population growth makes worse all those unfortunate situations, and the control of population density can buy us some time to control the rest of the problems,...
