8. The Nature Conservancy - a system of science-based international, governmental and public measures aimed at the rational use, reproduction, and protection of natural resources, protection of the environment from pollution and destruction in the interests of present and future generations.

9. For human nature - an environment of life and livelihood. A person needs a certain structure, and air pressure, pure natural water, plants and animals, the earth's temperature.

10. It's a wonderful world we live in. But now human beings are killing our planet. Millions of animals die every year because man has polluted their natural homes. Besides, every year people cut down more trees, build more roads, and use more land for farming. The country air, once clean and fresh,now may be polluted by power stations and factories.

11. People cut the trees down because they need wood and paper or new places for farms and houses. Even if new trees are planted, it takes many years for them to grow. Water is also polluted very much. There is a lot of litter on the beaches, and you can even see thick foam caused by chemical waste. Pollution is very dangerous for people, wildlife and the environment.

12. People don't just pollute the environment. They pollute themselves with cigarettes, alcohol and junk food. These are some of the world's most serious environmental problems. And it is no good pretending they don't exist - they do. What's more, they are getting worse all the time!

13. It is well known that people make all the problems themselves. But they seldom think what will happen then. Unfortunately people nowadays often tell lies, they argue and fight. Luckily, there are always ways out. We could improve our world, make it closer to the perfect one. In a perfect world people never argue, so they have no need to fight or make wars. All people work and get a lot of money so there are no crimes. They don't tell lies to each other.

14. People in the perfect world always protect nature. They travel on foot or by cars without petrol. So, you can often see people riding bicycles. People are healthy because they don't smoke, drink alcohol or take drags. They always eat healthy food: fruit and vegetables, dairy products. If I could improve our world the first thing I would do is stop people fighting. Secondly, I would, punish strictly those ones who make crimes. Finally, I would also make a law to protect our nature. And you?

15. As you may understand, our planet is in danger. Among the most serious problems, such as air pollution, water pollution, nuclear pollution we can underline dangerous diseases, people's interrelations, breaking human rights, crimes and drugs. Of course, all of the problems are very important, but we can list them in order of their importance. Drugs. Dangerous diseases. Pollution. Crimes. Endangered animals. New local wars. Dangerous technologies. Lack of recycling. People and their interrelations. Breaking human rights. Star wars.

16. What should and shouldn’t we do to protect our environment?

17. You are just one of 6,000 million people, who live on our Earth. So can your actions really make a difference to its future? The answer is yes, they certainly can. Because if you try to live in a way that will save the world rather than destroy it, you won't be alone. Your example will encourage your friends and family to do the same. Then they will tell their friends and families about helping to care for the environment.

18. Here are some ways in which you, your friends and your family can begin trying to save the Earth right now. 1)Try not to waste energy. Don't stand with the fridge door open while you wonder what to eat — make your mind up before you open the door. The fridge warms up when the door is open and it takes extra energy to make it cold again. 2)Keep yourself informed about environmental problems.

19. 3)Before you throw anything away, stop and think. Might someone else have a use for it? Charities are often pleased to have old books, clothes and toys. 4)Take as much rubbish as you can to local recycling centres. 5)If you have a choice avoid buying packaged goods. 6)Don't waste paper. When you are writing, use both sides of the paper. 7)Before you buy anything, ask yourself if you really need it. You don't need everything that adverts say you do. Try to avoid buying things you really don't have any use for.

20. 8)Walk or cycle whenever possible. 9)Never drop litter. 10)Help to clean up your local environment. There is probably a group in your area which spends weekends cleaning up ponds, rivers, parks and woods. Take some friends along and join the group — you'll have fun as well as helping the environment. 11)Try to reduce noise pollution. Don't take your radio outside — other people may not want to hear it. 12)Put out food for wild animals in winter.
