World population is estimated to have grown at the annual rate of 1.4% during the year 1990-2000. There is a net increase of three humans per second in the world population because in every second, on average, five children are born somewhere on earth and in that same second, two other people die.
In other words BRs (birth rate) are five per second and DRs (death rate) are two per second on earth. If you multiply this out, you will find we are growing at a rate of about 11,000 per hour, 2, 65,000 per day, or almost 100 million more people per month. By 1995, the world population had reached about 5.7 billion.
Many people worried that overpopulation will cause resource depletion and environmental degradation that threaten the ecological life. Others believe that human population is useful because it provides technology and enterprise that extend the world’s carrying capacity which allow us to overcome any problem we encounter.
A large population means a larger workforce, more genius, and more ideas about what to do. Along with every new mouth comes a pair of hands.
