14. Name some pollution problems and say how to solve them.
One of the greatest problems of the contemporary world is the pollution of the environment. We can part pollution problems to three group: Air pollution, Water pollution and Soil pollution. Causes of Air pollution are mainly power station using carbon and cars with normal fuel. Bought of this causes product carbon dioxide in the air. That is one of reason of global warming. We have to solve that problem so we should use another energy for example from wind, water, sun or atomic. We should reduce power station with carbon and use alternative fuel in car for example electric or hydrogen. Main reasons of Water pollution are oil getting out from oiler and dirty water with chemical pour out into lakes and rivers. We should be more careful with oil on the ocean. We need also build and use some filter sewer to our sewage. The biggest problem in soil pollution are dusts. Everywhere are different kind of dusts. We should majority of them give to recycling but first we have to segregate them. Another container to glass, another to paper and another to plastic.
