Экология и защита окружающей среды

Water is very important for life on the Earth. It is in oceans, seas, rivers and lakes. There is much water on our planet and at the same time there is little water on it. It is so because very little water on the Earth is good for drinking. In many rivers and lakes water is very dirty. Sometimes people cannot swim even in the sea because the sea and the seaside are not clean

The Earth is in danger

Ecology is a very popular word today. Ecology is a science which studies the relationships between all forms of life on our planet and the environment.

Water is very important for life on the Earth. It is in oceans, seas, rivers and lakes. There is much water on our planet and at the same time there is little water on it. It is so because very little water on the Earth is good for drinking. In many rivers and lakes water is very dirty. Sometimes people cannot swim even in the sea because the sea and the seaside are not clean. In many places water is not drinkable. It is dangerous to use it when you cook. Even fish die in such water.

For example Lake Baikal is the deepest freshwater lake on the Earth. It is 1741 meters deep. The lake is very beautiful but now it is in danger, because of the factories which are near it. At some places the water in the lake is so dirty that it can kill animals and plants in Baikal and near it.

The way people live has changed the climate on our planet. Nowadays the temperature is rising. You do not have real Russian winter in Moscow any more. In the north of Europe the climate has become milder and warmer too.

If the temperature grows by 3 – 4 degrees it will be impossible to live on the planet.

Some people’s activities do a lot of harm to the forests. Vast forests are cut down in Africa, South America and Asia for the needs of industries in Europe and the USA. People cut down trees to build farms, homes and roads. The loss of the forests upsets the oxygen balance. As a result some species of animals, birds, fish and plants have disappeared. Rivers and lakes dry up.

Every year the atmosphere is polluted by about 1000 tons of industrial dust and other harmful substances. Big cities suffer from smog. Cars have become the main source of pollution in industrial countries.

The pollution of the air and the world’s oceans are the other problems of mains careless attitude to ecology.

So, the problem now is to protect life on the Earth, to save our planet for people. That is why every year on the twenty second of April we celebrate the Earth Day. People  all over the world think about our planet. They think about air, water, plants and animals on the Earth. They say our planet is in danger. Many people do not know how to protect animal and plant worlds, how to keep the waters clean and the air fresh. But they are ready to do it. They try and help nature.
