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.

Health

People nowadays are more health-conscious than they used to be. They understand that good health is above wealth.

To be healthy we should avoid different bad habits that can affect our health. In my opinion, smoking and drinking too much alcohol, are the worst ones. It's common knowledge that smoking and drinking can shorten our lives dramatically. Smoking, for example, causes a number of heart and lung diseases, such as pneumonia, emphysema and cancer. Besides, it makes your teeth yellow and skin unhealthy. Fortunately, in recent years smoking has received a lot of bad publicity, and fewer people smoke nowadays. Some companies don't employ people who are smokers. Smoking has been banned in most public places because everyone agrees it does harm to our health. I don't smoke, because I don't want to have unhealthy skin and teeth and die young.

Smoking and drinking are joined by less dangerous habits, such as skipping meals, eating unhealthy food, or even overeating. Of course, they are not quite as deadly as smoking or drinking alcohol, but they also affect our health.

If we eat too much, we'll become obese, and obesity leads to serious health problems. A lot of people like drinking coca cola and coffee, and enjoy pizzas and hamburgers. But what is tasty is not always healthy. Fast food makes you fat, that's why Americans are the fattest people in the world.

In recent years eating habits have undergone a change. People are encouraged to eat less fat and more fibre. Fat is believed to be one of the major causes of obesity and heart disease. High fibre and low fat foods can now be found in all shops and supermarkets. Salads, beans, and fruit have taken the place of steak and ice cream. The fashion for health food is growing all the time.

Many people feel they are too fat, even if their doctors disagree. And a lot of people try to improve their fitness. There are a lot of ways to lose weight and avoid gaining it. Perhaps the most popular of them is following a diet. If you want to lose weight, you should cut out snacks and desserts, and cut down on fat. People have also become more aware of calories, the energy value of food. Some people count the number of calories they eat every day; so that they can try to take in fewer calories and lose weight. This is called a calorie-controlled diet. Manufacturers are increasingly producing special foods with fewer calories for slimmers.

But excessive dieting may be dangerous, too. Some people refuse to eat meat as they consider it harmful. They say a vegetarian diet reduces the risk of cancer and vegetarians live longer than others. I can't agree with them, because meat is an excellent source of good nutrition. In my opinion, it's wrong to put down a food simply because excessive amounts can cause health problems. Consumed in moderate amounts, meat is perfectly good for our health.

To my mind, the only way to stay healthy and to keep fit is by going in for sports. Among the benefits of regular exercise are a healthier heart, stronger bones, quicker reaction times and more resistance to various illnesses. Besides, you can eat and drink as much as you want because you are burning it all off.

To be healthy, it is also very important to spend a lot of time in the open air. It is useful to go for a walk before going to bed, or to air the room.

I think it is very important to be fit and healthy, and it is necessary to take care of your health. Being fat, in fact, can cause real problems. It is harder for fat people to get a good job, or even to make friends. If you want to do well, you must be thin. That's why I go in for sports on a regular basis. I have been doing aerobics for three years and I feel great. I am not enthusiastic about strict dieting, but I try to eat only low-fat food, and fruit and vegetables which are rich in vitamins.

Personally I believe that regularity in life promotes our health. Sleeping eight or nine hours, getting up early, regular meals, a healthy diet and going in for sports is really a good way to live.

toxis fumes, the air that we breather becomes polluted. This pollution is gathered in clods and with the oxygen and water in the atmosphere it becomes acid. When it rains, this pollution lands on trees, houses, buildings, cars, clothes, everywhere!!! This is called acid rain. When acid rain falls into laks, streams, rivers and seas, they become toxic. This is water pollution and it harms, kills or wipes out fish and plant species. When acid rain flows through the sil, it poisons trees and plants. Acid rain also causes serious damage to important building and objects. The good news is that governments have been trying to reduce the air pollution that causes acid rain.

April 22 is 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.

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 metres deep. The lake is very beautiful but now it is in great 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. People cut down trees to build farms, homes and roads. Many animals and plants lose their homes. This is bad for the Earth’s air too. Modern plants and factories send a lot of smoke into air. This is also very bad, because nowadays it’s difficult to breathe in big cities.

So, the problem now is to protect life on the Earth, to save our planet for people.
