If man does not believe the environment. There were few people on earth and natural resources seems to be unlimited.

Today is different. The world is too full. We use our natural resources and pollution of our environment with dangerous chemicals. If we continue to do so, would not survive life on Earth. 

We know that if the population can keep growing at current rates, a few years was enough food.What usually do to solve these problems?
 If you eat more vegetables and less meat, more food available. Croplands, feeding five times more people than the country where animals are kept.

Our natural resources will last longer if we learn recycie.

World population will grow so fast if people who use modern methods of birth control.

Finally, if we educate people, consider the problems that will have a better and cleaner planet for the future.
