population growth
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 mu
Each of these sectors claims cropland in almost every country. Considering all the above informatio and presentation of evidence, we must understand that rapid population growth is indeed a huge threat to our lives and our planet. Populatin growth in today's world, therefore, plays a vital role to changes in the land. Cassen states that: "Rapid population growth may affect poverty by affecting the correlates of poverty: low wages, lack of human capital such as education and health, and lack of income earning assets such as land; income inequality and loss of economic growth; and gender, and sometimes, race and ethnicity. As we all know we consume materials and energy from earth and then return heat and wastes to earth. 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. Water pollution has been partly caused by population growth. 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. Pirie says "The most serious contemporary threat, suppressing the threats of nuclear war and political upheaval, is the increasing disparity between food and population. Even in the USA, that has a statistical low population expansion, the natural parks experience a loss of species and habitat degradation due to immense numbers of people and their actions (365). Trough proper education, family planning, country policies and support of scientific research population density can be successfully controlled and our future will seem more prosperous. Globally, population growth is mainly responsible for land pressures (Turner II et.
