1.  People have lived on our planet for many years. We may live on different continents and in different countries, but we all depend on our planet, on the sun, on animals and plants around us. We must take care of Earth but not destruct wildlife. Many species of animals and birds are disappearing nowadays. We cut down trees to make furniture, but we forget that people can’t live without trees and plants. Every little creature or thing oh Earth plays its own part and makes our home unique.

2.  One of the biggest eco problems is pollution. The main reason of pollution is rubbish Most of our rubbish goes to big holes in the ground, called ’dumps’. But dumps are very dangerous for our life, because they are full of rats, which can carry infections away from dumps. Another way to get rid of rubbish is to burn it. But the fires make poisons, which go into the air and pollute it. This is the propel scientists should get interested in. Such researchers are worth spending money on.

3.  The Royal Society for the prevention of cruelty to animals (the RSPCA) tries to protect animals from bad use. It operates big nation campaigns aimed at lost pets and circus animals. The World Wildlife Fund (The WWF) rescued several species of animals mammals as well as birds. These organizations also helped to create more than 25C National parks. Greenpeace began its work 20 years ago from saving whales. And now Greenpeace is a world-famous organization, which saves plants, animals and people.

4.  Every year world industry pollutes the atmosphere with about 1000 million tons ol dust and harmful substances. Many cities suffer from smog. Vast forests are cut down and burn in fire. Their disappearance upsets the oxygen balance. As a result some rare species of animals, birds, fish and plants disappear forever, a number of lakes and rivers dry up. The pollution of air and the world destruction of the ozone layer is the result of man’s careless interaction with nature, a sign of ecological crises.

5.  Numerous conferences have been held to discuss questions of ecologically pool regions including the Aral Sea, the South Urals, Kuzbass, Donbass, Seiriipalatsinsfc and Chernobyl. An international environmental research center has been set up on Lake Baikal. Scientists are also doing much to preserve the environment. But these are only the initial steps that must be carried forward to protect not only for the sake of the present but for the future generations.
