Public attention to the problem of pollution has now become part of the contemporary life. The solution of this global problem requires the co-operation of all nations.

To protect nature people should change their attitude to it. Man should stop taking from nature everything he needs and give it his love instead. Otherwise the price that mankind will have to pay will be too high. It is good that at last people started to realise that they should keep air and water clean by establishing strict pollution control. Efforts are made to reduce pollution from automobile engines by developing pollution-free engines, which may eventually eliminate the more serious air pollution problems. Certain countries have already agreed to limit their carbon dioxide emissions.

It is important to install purifying systems for treatment of industrial waters, to protect rivers and seas from oil contamination. We should develop reservations and national parks for wild animals.

Why do some species of animals and plants disappear from the Earth?

– The disappearance of some species of animals and plants from the Earth is the result of the pollution of air, land and water. City and industrial waters, chemicals and fertilisers exhaust natural resources, endanger stocks of fish in the lakes, rivers and ponds. Moreover some animals were exterminated because of the people's greediness. These animals were hunted for the sake of fur or ivory, horns or tusks. In their everyday activity people needed timber turning the areas of thick forests into barren deserts.

– What can you say about global warming?

– Over the past two decades, the temperature of the Earth's atmosphere has gradually increased. Global warming is one of the climatic effects of polluted air. It worries a lot of people.

– Has anything been done to solve ecological problems?

– In recent years people have understood the necessity of protecting natural resources and wildlife. It becomes clear that to keep air and water clean, strict pollution control is necessary. Numerous anti-pollution acts passed in different countries led to considerable improvements.

– What will happen if nothing is done to protect the environment?

– If pollution of land, water and air continues, the damage caused by these to nature may become irreversible. If people carry on like this, the world will eventually run out of energy, fresh air and clean water. It can bring to the extermination of the people and turning the whole planet into either a desert or the North Pole. Serious actions must be taken now to avoid disaster.
