Pressing Problems Atmospheric pollution raises problems of several types. First, there are local problems due to the production of smoke and offensive gases by factories. Secondly, there are regional problems created by industrial agglomerations which may spread the same harmful effects over whole areas. Thirdly, there are some types of pollution such as those arising from nuclear explosives, which cover a con¬siderable portion of the globe. And lastly, there appeared one more type of pollution which is threatening the globe as a whole. Recent scientific research suggests that the protective layer of ozone around our planet seems to be under severe attack. In 1982 researchers first identified a hole over the Antarctic where the ozone layer is the thinnest. This was the first sign of a hole. Five years later the hole was reported, to grow to an area the size of the United States. The major cause of this weaking of the ozone layer is believed to be the increasing amount of harmful chemicals that are being released into the atmosphere by humankind. The fundamental importance of the ozone layer is that it acts as a filter intercept most of the sun's radiation including potentially harmful Ultra Violet B-rays which can cause cancer. Strong evidence now suggests that it is the growing industrial use of chlorine compounds called chlorofluorocarbons (CFCs) which is responsible for the hole. Researchers believe that the level of CFCs in the atmosphere is actually increasing by 5 per cent each year. Since 1969 the ozone level has fallen by 3 per cent over the densely populated cities of the US, Canada and Europe and by 4 per cent over Australia and New Zeland. In its «worst scenario» it is supposed that an over — thinning ozone layer could eventually allow a more harmful form of radiation known as ultra violet С to hit the earth Laboratory experiments have shown that Ultra Violet С can penetrate cells in the body and irreparably damage the nucleic acids and proteins which are the building blocks of life.
