The problem of ecology is very important today, because we live in a polluted world. People from all countries discuss environmental protection, but they still continue to pollute air, water and soil.

Plants and factories are being built near rivers and lakes. There are a lot of industrial waste in water and this kills animals, insects and plants.

There are several types of pollution: air pollution, water pollution and soil pollution.

Air pollution is caused by transport in big cities. Our cities are full of smog because of heavy traffic and people notice that it is hard to breathe there. Cars, buses and planes are the worst air polluters pouring harmful gases and smoke into the air and that causes lung diseases among people. We have acid rains because of air pollution 

Water pollution is another kind of danger. Factories throw wastes into rivers and lakes making them dirty. Animals die when they drink this water, people get sick when they swim in it and eat fish that live there.

Soil pollution stops plants from growing and makes people sick when they eat fruit and vegetables grown on polluted soil. People also pollute soil by leaving rubbish on it. Forests are full of used bottles and cans. 

Every day we throw away a lot of rubbish However, we can use it again. Everybody must know the three R's: Reduce, Reuse and Recycle. We can reduce the usage of water and electricity. We should reuse whatever we can, for example, plastic bags, paper, cans, glass and bottles.

People need to invent new free technologies that will be safe for nature. There are new inventions such as filters that make water and air clean and prevent pollution. Special kinds of gasoline for cars can help to reduce air pollution.

We must not ignore the problems of environmental pollution and try to make everything possible to reduce if not stop it.
