Ecological problems

Air pollution is  one of the most urgent  environmental problems. Hazardous atmospheric emissions have increased with the development of industry and transport.

Air in big cities is a lot more polluted than air in the countryside. In 1997 many countries signed the  Kyoto Protocol  in an effort to fight air pollution.

Global warming is  the result of human activity . The industrial development causes the release of harmful substances into the atmosphere.

That means that air on our planet  is getting hotter . This results in such consequences as raising of water level in the World ocean and changes in agricultural productivity.

Water pollution is another serious problem. Plants and factories release harmful substances not only into the air but  into the natural reservoirs, too .

As a result of that, animals and plants  lose their habitat , and people suffer from the  shortage of high-quality drinking water.

Lately, animal world and plant kingdom of our planet have been at serious risk as human activity endangers their serene existence.

Ecosystems play an important role and  preserving biodiversity is vital for our planet.  Extermination of animals and carelessness towards plants  must be prevented .

It is well known that our planet is  overpopulated . This depletes natural resources.

Some countries already suffer from  scarcity of water, food and fuel . Our mission is to act towards natural resources with care and use them efficiently.

The extinction of animals and plants .

Today forests cover  about 30% of land . Every year this figure decreases more and more.

People clear new territories for residential buildings, new plants and factories. We must realize that deforestation causes  the extinction of animals and plants .
