There are a lot of reasons which can cause the disaster in our natural environment. First of all, all factories and cars release poisonous gases into the air. Then theses chemical gases mix with the water in the clouds. This polluted substance falls like rain called acid rain. It causes some damages in buildings and forests. What is more, it pollutes lakes and rivers. There are too many different harmful gases produced by factories that they can't be cleared away in natural way, for example by rain. Often factories poured their sewages into the natural reservoirs of water such as an ocean or a river, which is very harmful for fishes. It can be dangerous for people too, if they use this polluted. The other problem is the haloalkane - a substance used in aerosol sprays or refrigerators. It damages the atmosphere and causes the hole in the ozone layer (A thin layer of atmosphere is called by experts a hole in the ozone layer). It is proved that because of the hole in the ozone layer many people suffer the skin cancer. Global warming belongs to the most serious problems of our environment. Because of it the Sahara Desert is getting bigger and ice on the North Pole is melting. Too much rubbish is produced and there aren't enough landfill sides. This can results in spreading many diseases. As the forests are cut down, there is less and less oxygen, so people started having problems with breathing. Too much carbon dioxide is very harmful for all living creatures. To sum up, our environment is too polluted and we all take the responsibility for this situation.
