Environmental protection.
Our earth is our home, so if we want to protect our home we should protect our environment from harmful effects of human activity. Some of these activities cause pollution. Pollution now is a very important problem. Some of these problem are : the ozone holes, global warming ( or green-house effect), acid rain … The ozone layer is a layer of gases which stop harmful radiation from the sun protecting the earth. Recent research shows that there is a hole in part of the ozone layer which is caused by smoke from factories, car exhaust fumes, aerosol cans ‘cause they contain CFC. Global warming is an increase in world temperature caused by an increase in carbon dioxide. Acid rain is rain that contains dangerous chemicals, this is caused by smoke from factories. Another problem is poisons in food. Farmer soften spray chemicals in crops to safe them from pests. These chemicals are called pesticides. Scientists have found that pesticides often end up in our food and they can cause health problems - especially for kids. The seas are in danger. They are filled with poison : industrial, chemical, nuclear waste. Every ten minutes one kind of animal, plant or insect dies out for ever. And if nothing is done our earth will die in about 30 years from now. So what can we do to protect our environment ? I think that we should recycle our used things, we should plant more trees, we should not waste resources but try save them, we also must make smoke from factories and car’s fumes more clean, we must not dump industrial waste to seas and rivers …Now people are beginning to realize that environmental problems are not somebody else’s. They make different organization, whose aim is conservation. For example “ GREEN PEACE ” , “ FRIEND OF THE EARTH ” and others. Everyday millions people from all over the world do everything to protect our environment , and they need for our help. I think we ought to help them , just to make our future better.

Environmental protection

Some hundreds of years ago people lived in harmony with nature, because industry was not much developed. Today, however, the contradictions between man and nature are dramatic.
The twenty first century is a century of the scientific and technological progress. The achievements of the mankind in mechanization and automation of industrial processes, in chemical industry and conquering outer space, in the creation of atomic power stations and ships are amazing. But at the same time, this progress gave birth to a very serious problem – the problem of environment.
Ecology and the contamination of environment, is concerned with climate, over-population in certain areas, deaths of plant and animals, chemical contamination of seas, lakes and rivers as well as atomic experiments and dumping of atomic waste from power stations. Floods, unexpected draughts, and the greenhouse effect are the next reasons.
There are many consequences of damaging the environment. One of them is acid rain. Another one is water shortage resulting from abuse of arable lands in agriculture. The third one is destroying the ozone layer of the Earth through pollution from factories and plants. The fourth problem is damage o water and soils. The fifth one is damage to wildlife: numerous species of animals and plants can disappear. At last, the most serious danger arising from damaging the environment is the result of the abovementioned consequences. This is the danger for the life and health of the man.
The protection of natural resources and wildlife is becoming a political programme in every country. Numerous anti-pollution acts passed in different countries led to considerable improvements in environment. In many countries purifying systems for treatment of industrial waters have been installed, measures have been taken to protect rivers and seas from oil waters.
But the environmental problems have grown beyond the concern of a single country. Their solution requires the co-operation of all nations.
If we are unable to learn to use the environment carefully and protect it from damage caused by man’s activities, very soon we’ll have no world to live in.
