Ecology is a science which studies the relationship between all forms of life on our planet with its environment.

  British and American children learn a lot about the environment at school.All of them remember thethree R’s:

  What can or must we reduce? (уменьшать) reuse? (использовать заново) recycle? (перерабатывать) We can reduce using electricity. We can reduce using water. We must recycle cartons. We must reuse glass bottles. We can recycle newspapers. We must recycle paper. We can recycle plastic containers. All these actions help to reduce pollution, deforestation and not to damage the nature.

  “To hurt the Earth is to hurt yourself “

  Do you agree with this statement? Why? Why not? Give your examples. This is teen’s opinion: I agree with this statement “to hurt the Earth is to hurt yourself” because the Earth is our home. Everything is connected. When we pollute air and water we spoil the things we use because we breath this air and drink this water. If the balance in nature is destroyed we will die too.

  Are you worried about nature?

  The Earth is more than the place we call home. The Earth is our environment. It means that the land, air, water and wildlife that surround us affect the way we live. And the way we live affects the natural world outside our front door. A lot of people understand this and see urgent environmental problems. 52% think that water pollution is a problem. 43% think that when trees are cut down it is a problem. Air pollution is a problem for 32%.

  Who is in Charge of the Planet?

  A lot of people think about the future of the planet. Some people take care of animals, others take care of birds, others are in charge of forests. I think children can help the planet. They can recycle. They can plant trees and help animals. If they don’t leave litter and don’t damage wildlife the nature is not spoiled. It is important that children should take part in saving Earth. We are in charge of the planet because we all pollute it and I think that we all should try to help it.

  The Baltic, a Sea Of Waste

      Pollution is a serious problem. It effect everyone every day. Where does the pollution come from? Is it only factories, big ships and cars that pollute? No, it is you and me as well. If you drop litter, you pollute. That's how it begins. What happens when millions of people do the same thing?     Most big cities pour their waste into seas and rivers. The first alarm came from Japan. Some sixty people died as they had eaten polluted fish.        The Baltic is a special case. Because it is such a small sea it becomes dirty very easily. Its water changes slowly. As many as 250 rivers run into the Baltic. There are hundreds of factories on these rivers and millions of people live along them. Seven industrial countries surround the Baltic. A lot of big cities lie on its coast. All of this combined with the active navigation of the affects the state of the sea water and the shore line flora and fauna.             It is difficult to clean it now. Fortunately all the countries in the Baltic area have realized the problem. They cooperate in solving ecological problems of the Baltic basin. The aim of the agreements is to prevent pollution of the sea and to preserve sea life.

How do scientists, journalists, teachers, public and political leaders draw peoples” attention to the problems of environmental protection? Explain how and why our attitude towards nature is changing together with the knowledge we are getting. Speak about the practical steps which are being undertaken environment. Man”s survival depends upon the way he treats for protecting our his environment. Say in what way this is true. It is our responsibility to preserve this planet for future generations.
