Cars disappear from the roads, and boats disappear from the rivers. Streets, beaches and parks that are usually full of people become empty. What would happen to the natural world? At first, some things would get worse. Without people to look after them, many buildings would fall down. But soon, nature would show its power. The noise would drop greatly as traffic stops. The natural wonders which have been hidden by pollution for years would appear again. Animals would soon increase in number, and green plants would cover the empty streets. However, humans are part of nature, too. The problem is not people themselves, but the way they treat the earth. During the past centuries, the rapid development of human society has made us care less for nature, and many animals are now in danger. But it is not too late.
