Conserving The World’s Natural Resources

In the decade of the 1970s, the United Nations organised 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 2010 there will be over 6 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 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.
