I would like to tell you about the main ecological problems of our city, my native Tyumen, and our region. They are: littering, air pollution, water pollution, endangered species, destruction of natural resources and others. People cut down forests, pollute air and water. Water is the liquid of life. Man consists of 70% of water, so using water is necessary to sustain our lives. Earth is a "blue planet", but actually, the amount of fresh water suitable for drinking, is very limited because of the detrimental impact of human activities. Therefore, the problem of drinking water is urgent nowadays. The main source of pollution is agriculture, industry and household waste, as well as pathogens. Besides, the water absorbs harmful to human health impurities - rust, heavy metals, chlorine in the pipes through which the water enters our apartments. What can we do? How to make our water clean, how to save it? We must turn to our government, scientists, all people of our city to call them to do the best for the prevention of pollution of water! Adults must better dispose waste of human life, build treatment facilities. And of course, we have to save drinking water, not to let it just flow into nowhere. It can be done even by a child. Teach him to close the faucet with drinking water when it is not needed. Only together we will save not only our native city od Tyumen but all our planet and live happily. We must begin from our houses, streets and make our city clean.
