Презентация на тему:"Экология"

People have always polluted their surroundings.

But until now pollution was not such a serious problem.

In past most people lived in rural areas and didn’t have

pollution-causing machines. But with the development of

crowded industrial cities the problem of pollution has become

more important. Using automobiles and other machines made

pollution steadily worse. Since the 1950’s people have become

alarmed with the danger of environmental 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 products can’t be grown. In addition environmental

pollution spoils the natural beauty of our planet.

Pollution is a very complicated and serious problem. Automobiles are polluting the air but they provide fast transportation for the people. Plants and factories pollute the air and water but they provide jobs for people and produce necessary goods. Fertilizers and pesticides are important for growing crops but they pollute soil.

Thus , people would have to stop using many useful things if they

wanted to end pollution immediately. Most people don’t agree to do that.

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

pollution. Individuals and groups of people can work together to

persuade enterprises to stop polluting environment.

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.
