People have always polluted their surroundings. But until now pollution was not such a serious problem. People lived in uncrowned rural areas and did not have pollution — causing machines. With the development of crowded industrial cities which put huge amounts of pollutants into small areas, the problem has become more important. Automobiles and other new inventions make pollution steadily worse. Since the late 1960's people have become alarmed with the danger of pollution. Air, water, and soil are necessary for existence of all living things. But polluted air can cause illness, and even death. Polluted water kills fish and other marine life. On polluted soil, food can not be grown. In addition environmental pollution spoils the natural beauty of our planet. Pollution is as complicated as serious problem. Automobiles are polluting the air but they provide transportation for the people. Factories pollute the air and the water but they provide jobs for people and produce necessary goods. Fertilizers and pesticides are important for growing crops but they can ruin soil. Thus, people would have to stop using many useful things if they wanted to end pollution immediately. Most people do not want that of course. But pollution can be reduced gradually. Scientists and engineers can find the ways to reduce pollution from automobiles and factories. Government can pass the laws that would make enterprises take measures for reducing of pollution. Individuals and groups of people can work together to persuade enterprises to stop polluting activities.

 Люди всегда загрязняли окружающую среду. Однако до последнего времени загрязнение не было такой серьезной проблемой. Люди жили в слабозаселенных сельскохозяйственных областях, у них не было загрязняющих природу машин. С развитием перенаселенных промышленных городов, в которых огромные количества отходов выбрасывались на маленькой площади, эта проблема стала гораздо серьезнее. Автомобили и другие новые изобретения делают загрязнение все интенсивнее. В конце 60-х годов люди начали ощущать тревогу в связи с опасностью загрязнения окружающей среды. Воздух, вода и почва необходимы для существования всех живых существ. Однако загрязненный воздух может послужить причиной болезни и даже смерти. Загрязненная вода убивает рыб и других морских животных. На загрязненной почве не могут выращиваться пищевые культуры. Кроме того, загрязнение окружающей среды портит природную красоту нашей планеты. Проблема загрязнения окружающей среды так же сложна, как и серьезна. Автомобили загрязняют воздух, но предоставляют людям возможность передвижения. Фабрики загрязняют воздух и воду, но они предоставляют работу людям и производят необходимые товары. Удобрения и пестициды важны для сельского хозяйства, но они могут разрушать почву. Таким образом, людям пришлось бы прекратить пользоваться многими полезными вещами, если бы они захотели прекратить загрязнение окружающей среды сразу. Большинство людей, конечно, этого не хочет. Однако загрязнение может быть сокращено постепенно. Ученые и инженеры могут найти пути сокращения вредных выбросов от автомобилей и фабрик. Правительство может издать законы, которые бы заставили предприятия принять меры для уменьшения загрязнения. Отдельные лица и группы людей могут сотрудничать, чтобы убедить предприятия прекратить виды деятельности, вызывающие загрязнение окружающей среды.
 

Environmental Problems .Загрязнение окружающей среды Environmental problems have become one of the most urgent problems of modern society. More and more people suffer from air and water pollution. Nature also suffers from land and nuclear pollution. The reasons for such environmental problems are numerous. Among them increasing number of cars in the streets, factory waste, millions of cut down trees, destroyed habitats of animals, contaminated rivers and seas. All these problems mainly arise due to human careless activities and gradually destroy our planet. If we look closely, we’ll notice that not only one city is under danger, but the majority of world population. Fortunately, there are many ways to suspend these problems. If everybody starts caring about the planet we live on, many environmental problems can be solved. For example, if we start recycling paper and cardboard, we can save lots of trees. If we start using public transport more than private cars, we can have less air pollution. Local governments can also help to prevent some problems, if they forbid logging companies to destroy the forests, or stop factories from polluting water. The most important thing is, of course, to start acting immediately, otherwise we might have to face many global disasters.
