     In many countries today, laws protect wildlife. In India the need for such protection was realized centuries

ago.

     About 300 BC, an Indian writer described forests that were somewhat like national parks today. The killing

of game animals was carefully governed. Some animals were fully protected. Within the forest, nobody was

allowed to cut trees, burn woods, or trap animals for their furs. Animals that became dangerous to human

visitors were trapped or killed outside the park so that other animals would not become uneasy.

     The need for wildlife protection is greater now than ever before. About a thousand sorts of animals are in

danger of extinction, and the speed at which they are being destroyed has been putting on. With mammals, for

example, the speed of extinction is now about one sort every year; from AD l to 1800, the speed was about one

sort every fifty years. Everywhere, men are trying to solve the problem of saving wildlife while caring for the

world's growing population.
