There is so much smoke inthe air that it is unhealthy to live in many of the world’s cities. In one well-known city, for example, poisonous gasesfrom 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 waste-land all over the world. As the result, farmers inparts of Africa cannot grow enough to eat. In certain countries in Asia there is too little rice. Moreover, we do not takeenough care of the countryside. Wild animals are quickly disappearing. For instance, tigers are rare in India now becausewe have killed too many to survive. However, it is not enough simply to talk about the problem. We must act now beforeit is too late to do anything about it. Join us now. Save the Earth.
