We live on the earth. It is very, very big. There is a lot of water on the earth. It is in rivers, lakes, seas and oceans. There are a lot of forests and fields, hills and mountains on it. The earth is full of wonders. Different animals live on the earth. Different plants grow on it. The earth is beautiful. There are large countries and small countries. There are warm countries and cold countries. There are some countries where there are four seasons in a year and some countries where there are only two. When the sun shines it is day. When the sun does not shine it is night. When it is day in one country it is night in another. You can see the moon and the stars in the sky at night. People live in different countries. They speak different languages.
People have lived on our planet for many years. They lived and live on different continents, in different countries. People depend on their planet, on the sun, on animals and plants around them. People must take care of Earth. Our ecology becomes worse and worse with every new day. Many species of animals and birds are disappearing nowadays. People destruct wildlife, cut down trees to make furniture. They forget that people can’t live without trees and plants, because they fill air with oxygen. And, of course, great problems are population and animals destruction. 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 ‘cause 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. But pollution isn’t the only actual problem. Every day a big number of animals disappears . People kill animals for different aims: e.g. people hunt whales for their meat and oil; elephants for their tusks, crocodiles for their leather and so on. And also animals are used for medical experiments. The most wide – speared from such animals are monkeys. Modern life is bad for animals, birds, fish. The air isn’t fresh and the water isn’t pure. They don’t have good meal and facilities for the life. You can find their names in the Red Book.
