CONSERVING THE WORLD'S NATURAL RESOURCES

In the decade of the 1970s, the United Nations organized several important meetings on the human environment to study a very serious problem. We humans are destroying the world around us. We are using up all of our natural resources. We must learn to conserve them, or life will be very bad for our children and our grandchildren

There are several major parts to this problem

Population :  Most problems of the environment come from population growth. In 1700 there were 625 million people in the world. In 1900 there were 1.6 billion, in 1950 2.5 billion, and in 1980 4.4 billion. In the year 2000 there will be 6.3 billion. More people need more water, more food, more wood, and more petroleum

Distribution : Scientists say there is enough water in the world for everyone, but some countries have a lot of water and some have only a little. Some areas get all their rain during one season. The rest of the year is dry

There are huge forests in the Amazon area of Brazil. In other parts of the world there is only desert

Petroleum : We are using up the world's petroleum. We use it in our cars and to heat our buildings in winter

Farmers use petrochemicals to make the soil rich. They use them to kill insects that eat plants. These chemicals go into rivers and lakes and kill the fish there. Thousands of people also die from these chemicals every year. Chemicals also go into the air and pollute it. Winds carry this polluted air to other countries and other continents

Poverty : Poor farmers use the same land over and over. The land needs a rest so it will be better next year. However, the farmer must have food this year. Poor people cut down trees for firewood. In some areas when the trees are gone, the land becomes desert. However, people need wood to cook their food now. Poor people cannot save the environment for the future

We now have the information and the ability to solve these huge problems. However, this is not a problem for one country or one area of the world. It is a problem for all humans. The people and the nations of the world must work together to conserve the world's resources. No one controls the future, but we all help make it
