The problem of environment protection is actual. Much attention is paid to the problem of ecology. The present situation is too far complicated. Many flowers have become rare and vanish. Our useful insects: bees, bumble-bees, butterflies, dragonflies can’t live in the atmosphere of chemicals and pesticides. Excessive radiation and transport are harmful to people and animals. We know that a great number of people all over the world are taking part in the policy of controlling the atmosphere, the water, the climatic changes of man’s interference in nature. The problems of environment include a wide range of burning issues: nature destruction and pollution, extermination of wild life on global scale, endangering human health with industrial wastes. I think we may make the Earth a safer and better place. We mustn’t put waste into the seas and rivers and we must stop those who do it. We can’t be indifferent, we must protect animals in danger and increase their population creating favorable conditions. Governments ought to make tough laws against litter. We must find ways of preventing oil spills and we must ban cars which use leaded patrol. It is better not to use products that damage the ozone layer. Theses problems become very pressing, the subject of many scientific meetings. Let everybody remember: we live only once and not a very long life. We have one earth for all those who love it and who do not.
