 1. It’s a wonderful world we live in. For thousands of years the earth has given support to all forms of life - human beings, animals, birds, fishes, insects and plants. But now human beings are killing our planet.   Many species of animals and birds have disappeared. Millions of animals die every year, because man polluted their natural homes. The rivers that used to be full of fish - are empty of fish now. In some rivers you can see thick foam caused by chemical wastes. The forests are disappearing, people cut down trees because they need wood and paper. Seedlings are damaged. Damage and pollution cause great harm to the environment. If people hadn’t thrown away so much rubbish, the Earth would have been safe now.

       2. There are a lot of wonderful treasures in the world. Hundreds of thousand tourists come to them every year. Tourists take photos, admire   beautiful landscapes but they don’t think about troubles, dangers and pollution. Time is running out and beautiful places may become dangerous places. All over the world people have built plants, factories and power stations, which produce chemical wastes and throw it away in the environment.  A lot of people travel by cars and motor cars, leave rubbish in the places of their picnics and they don’t always think about air pollution, pollution of rivers, lakes, meadows and forests. If people didn’t throw away tons of rubbish they wouldn’t have so many environmental problems now.

       3. European family with two children throws away  50 kilos of paper and  60 kilos of plastic, that means that one person throws away 12 kilos of paper and 15 kilos of plastic. It is also known that every person throws away 70 food cans and 70 drink cans. According to  my mathematical  calculation  - the class of 25 students throws away 300 kilos of paper, 375 kilos of plastic,  1,890 food cans and as well as   drink cans.

It is known that every year in Russia each person produces about 57 kilos of plastic waste. It means that Russia with its population of 146, 804, 372   people produces  8, 367, 849, 204 eight billion three hundred sixty seven million eight hundred forty nine thousand two hundred and four  tons of plastic waste every year!  Doing simple mathematical calculation, we see that the amount of rubbish thrown into the environment is shocking!

       4. So to change the situation to the best people in the USA started up the first national park it was Yellowstone in eighteen seventy two (1872). After that national parks appeared in many other countries. Nowadays there are 41 national parks in Russia. Among them “Losinyi Ostrov” in Sochi, “Samarskaya Luka”, “Mariy Cherda”, Pribaltiisky and  Zabaikalsky national parks, “Prielbrusye”, “Bashkiriya”, “Russkaya Antarktika” and others.

      5. In the Soviet Union only paper was used for packaging, glass cans and bottles were carefully collected and reused. There were no polythene packets, plastic cans and bottles. The number of houses was less and less forests were cut down for wood. People were more eco-friendly. We are not against progress and human activity in developing industry, but we should be well-educated, clever and careful.

      6. We live among the litter and waste which we have created ourselves. People don’t just pollute the environment. They pollute themselves with cigarettes, alcohol and junk food.

      7.  People say that in the Soviet Union several times a year pioneers competed in collecting waste paper and scrap   metal which were taken to recycling centers. But today in the country side it remains in the fields and on the roadsides unless the people who live nearby pick it up. It can kill or hurt farm animals.

       8. These are the most serious environmental problems. And it’s no good pretending they don’t exist – they do. What’s more, they are getting worse all the time! What will happen if we don’t try to solve these problems? Scientists have made predictions and they are alarming.
