It is a small world we live in, and it is high time for all of us to realize it. Nature seemed to be boundless and endless. Millions of cars and smoky factories pollute and spoil the air we breathe in. It is hurting our lungs as well as the life of animals, birds and plants. We don't know what to do with waste materials of our industry, so we pour them into water, bury them into soil, shoot them into atmosphere. As a result, radiation represents one of the main problems nowadays.
With development of our civilization we have become dangerous to the planet and to ourselves.
In many countries environmental protection agencies and research centers are up. Such organizations as "Green Peace" and "Friends of the earth" care for ecology in their countries. There are over 300 nature centers in British cities and more then 30 in London. Children go there with their teachers to study and enjoy nature. There are a lot of environment groups in Britain: "Friends of the earth", "Green Peace", London Wildlife Trust, etc.
People need wood and paper, so we cut down our forests. And today we do all we can to protect them. We have learned that forests are very valuable. They give us wood, which we use in many new ways. People do their best to protect our forests. Each of us can help to protect the forests. We can plant young trees and protect them.
People all over the world do everything to save nature.
