1. Nature and Man Made by: Savinova Olga

2. Introduction Since ancient times Nature has served Man, being the source of his life. For thousands of years people lived in harmony with environment and it seemed to them that natural riches were unlimited. But people always polluted our Nature.

3. Factories emit tons of harmful chemicals. These emissions have disastrous consequences for our planet. They are the main reason for the greenhouse effect and acid rains. But they provide jobs for people and produce necessary goods.

4. Our forests are disappearing because they are cut down or burnt. If this trend continues, one day we won’t have enough oxygen to breathe, we won’t see a beautiful green forest at all.

5. Automobiles are polluting the air but they provide transportation for the people.

6. Fertilizers and pesticides are important for growing crops but they can ruin soil.

7. Decisions of this problem: Scientists and engineers can find the ways to reduce pollution from automobiles and factories. Government can pass the laws that would make enterprises take measured for reducing of pollution. Individuals and groups of people can work together to persuade enterprises to stop polluting activities.
