World Population
Human population has grown more rapidly during the last century than it ever has before. There are more than 3 times as many people on earth today, than there was at the beginning of the twentieth century.

It is the countries with fast population growth that are suffering from rapid environmental changes and problems. Many people believe that that we are headed straight into a world population crisis.
The population growth in Third World Countries is becoming harder to control. Most fast growing countries have populations too large to control. These countries go through rapid ecological changes by consuming their own natural resources and financial resources, faster than they can be produced. This can lead to increasing death rates from starvation and the lowering of living standards. These fast growing countries that have high populations may eventually permanently reduce the carrying capacity of their home land.
