Ecology and Environmental Protection.

Ecology is the study of the environment and the way plants, animals, and humans live together and affect each other. This word came from the Greek ‘oikos’ which means ‘home’. The problem of protecting nature is of a primary importance today. Through their daily activities people pollute water, air, soil. If we do not stop these activities the damage may become irreversible. The Earth is suffering many ecological problems. One of them is air pollution. Urban air pollution continues toexpand as a result of the increased number of motor vehicles. Exhaust fumes from the engines of automobiles contain a number of polluting substances. Tokyo has such a serious air-pollution problem that oxygen is supplied to policemen who direct traffic at busy interchanges. Milan, Ankara, Mexico City, and Buenos Aires face similar problems. Air pollution destroys the ozone layer which protects the Earth from the dangerous light of the Sun. In accordance with the Kyoto agreement it was suggested to introduce a special carbon tax in order to reduce the greenhouse effect. One of the climatic effects of air pollution is acid rain. It is damaging to water, forest, and soil resources. It is blamed for the disappearanceof fish from many lakes, for the widespread death of forests in European mountains, and for damaging tree throughout the world. Acid rain has been reported in areas as far apart as Sweden and Canada, and in parts of the Russian Federation from Moscow to the Urals. The second important problem is water pollution. Plants and factories put trash into seas, lakes and rivers. Many birds and fish die because of the polluted water. Another acute problem is water shortage resulting from the abuseof arable lands in agriculture. People also concern over the dangers resulting from massive releases of radioactive materials from nuclear weapons, which, if used on a major scale, could seriously endanger all of humanity. Another concern is accidents at nuclear power plants. In 1978 a nuclear power plant in Pennsylvania suffered a severe accident leading to partial meltdown of its radioactive core. In 1986 the Chernobyl nuclear power plant near Kiev suffered a fire and partial meltdown, resulting in a major release of radioactive particles. Much of northern and eastern Europe experienced heavy nuclear fallout. Industries located along waterways downstream contribute a number of chemical pollutants, some of which are toxic. Another form of pollution typical for industrial societies is noise. Waste is an enormous problem too. A third of all waste is burnt which leads to contaminationof air, water and soil. That is why waste recycling is so important in most European countries. In recent years the pollution problems have received great publicity. The media have begun to campaign against tin cans and trash. Protection of natural resources and wildlife is becoming a political programme in every country. Numerous anti-pollution acts adopted in different countries have led to considerable improvements in environment. Non-political environmental organisation Greenpeace has gained widespread trust and support. In many countries purifying systems for treatment of industrial waters have been installed and measures have been taken to protect rivers and seas from oil waters.  To protect nature people should change their attitude to it. Man should stop taking from it everything he needs, he must give it his love instead. Otherwise thepayoff will be too high. It is good that eventually people started to realize that they should keep air and water clean by establishing strict pollution control. Efforts are being made to reduce pollution from automobiles by developing pollution-free engines which may eventually eliminate more serious air pollution problems. Moreover, the strong public reaction can facilitate the exercise of the absolute pollution control in various contaminated industries.
