For hundreds of thousands of years, the human population grew at a low but steadily increasing rate. Then, in less than last 200 years, the world population went from several hundreds of millions to more than 6 billion people.
Many people believe that these resources, both the Earth and the human intellect are endless and population growth can continue and that there is no danger that we will ever run out of anything. "Yet, many people had predicted catastrophic shortages of natural resources that would follow, because of continued population growth. Countries try not to raise this subject to the public much, because they do not want to raise panic.
Overpopulation is destroying our environment, lowering the standard of living, and generally degrading the quality of life. Overpopulation also causes more violence, environmental pollution that reflects on land degradation, tropical forest destruction, global warming and destruction of coral reefs.
Every second five people are born and two people die, so there is a gain of three people. At this rate, the world population is doubling every 40 years and would be: 12 billions in 40 years, 24 billions in 80 years and 48 billions in 120 years. But the Earth could provide food only for 20 billions people.
