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 contro
First, population growth has serious effects on the environment. Specifically land, forest and water are some of the vital resources that are threatened by enlargement of population density. As we all know we consume materials and energy from earth and then return heat and wastes to earth. Each of these sectors claims cropland in almost every country. Let us now proceed to the presentation of the problems concerning food supplies caused in large degree by population expansion. Population growth has as a result the decrease of fresh water resources; humans apply pressure on water quantity through water needs for survival, hygiene and agriculture. Labor forces, which were available, resulted to "land-clearing", alteration and loss of the land"tms quality. These human actions plus population expansion and the necessity has as a result the deterioration of water quality in rivers, with effects by human actions and development on or close to them (267). Pirie says "The most serious contemporary threat, suppressing the threats of nuclear war and political upheaval, is the increasing disparity between food and population. Globally, population growth is mainly responsible for land pressures (Turner II et. Because population growth has expanded greatly over the last 500 years , as larger numbers of people needed more food supplies and commodities from natural resources and agricultural activities, more and more people occupied biger land spaces in big urban areas. Water pollution has been partly caused by population growth.
