We are all slowly destroying the earth. The seas and rivers are too dirty to swim in. There
is so much smoke in the air that it is unhealthy to live in many of the world's cities. In one
well-known city, for example, poisonous gases from cars pollute the air so much that traffic
policemen have to wear oxygen masks.
We have cut down so many trees that there are now vast areas of wasteland all over the
world. As a result, farmers in parts of Africa cannot grow enough to eat. In certain countries
in Asia there is too little rice. Moreover, we do not take enough care of the countryside. Wild
animals are quickly disappearing. For instance, tigers are rare in India now because we have
killed too many for them to survive. However, it isn't enough simply to talk about the problem.
We must act now before it is too late to do anything about it. Join us now. Save the Earth. This
is too important to ignore.
