Ecology
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.
The planet Earth is only a tiny part of the universe, but it's the only place where human beings can live. Today, our planet is in serious danger. Acid rains, global warming, air and water pollution, overpopulation are the problems that threaten human life on Earth.
Who is to blame for the disaster? The answer is simple: all of us. Our forests are disappearing because they are cut down or burnt. If this trend continues, one day we won't have enough oxygen to breathe.
The seas are in danger. They are filled with poison: industrial and nuclear waste, chemical fertilisers and pesticides. The Mediterranean is already nearly dead; the North Sea is following. The Aral Sea is on the brink of extinction. If nothing is done about it, one day nothing will be able to live in the seas.Every ten minutes one kind of animal, plant or insect dies out for ever. If nothing is done about it, one million species that are alive today may soon become extinct.
Air pollution is another serious problem. In Cairo just breathing the air is dangerous — equivalent to smoking two packs of cigarettes a day. The same holds true for many Russian cities. Factories emit tons of harmful chemicals. These emissions have disastrous consequences for our planet. They are the main reason for the greenhouse effect and acid rains. An even greater threat are nuclear power stations. We all know how tragic the consequences of the Chernobyl disaster are.
Fortunately, it's not too late to solve these problems. We have the time, the money and even the technology to make our planet a better, cleaner and safer place. We can plant trees and create parks for endangered species. We can recycle litter. We can support green parties and put pressure on those in power. Together we can save the planet and all of us with it.
Of course, people can't stay indifferent to these problems. There are a lot of special organizations, which try to save our nature. The most known are: The Royal Society for the prevention of cruelty to animals (The RSPCA), the World Wildlife Fund (WWF) and Greenpeace. The RSPCA tries to protect animals from bad use. It operates big nation campaigns aimed at lost pets, circus animals. The WWF rescued several species of animals, mammals as well as birds. These organization also helped to create more than 250 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. These organization, want to rescue animals, to help them to survive and to save jungle rain forests, which are in danger of destruction. And they also help animals 'cause many of them have already gone as they have nowhere to live. Their homes, the trees, have disappeared. We must save wild animals. And we must find the right way to save land, people and animals. We must lake care of nature, because we are part of it.
I would advise everyone to think about this problem. Together we can find a solution!
