Reading Прочитать текст «Ecological problems»  As the twentieth century draws to a close, global concentrations of atmospheric pollution seriously threaten the ozone layer. It means the increasing concentration of greenhouse gases and increased ozone depletion. This threatens to lead to dramatic climatic changes or global warming. To reduce these threats, the scientists of the various countries of the world say that global emissions must be sharply curtailed.  A number of gases contribute significantly to the stock of greenhouse gases. CO2 has the greatest impact. The burning of fuels by automobiles and industries are main sources of greenhouse gases.  Less damaging sources include deforestation, animal husbandry, wet rice cultivation, decomposition of waste, and coal mining.  Together all developing countries, with roughly three-quarters of the world’s population, produce less than one-third of industrial CO2.  Because incomes and consumption are higher in the wealthiest countries, per capita emissions are much higher. For example, the level of per capita emissions in the United States is more than twice bigger than that in Europe, 19 times higher than that in Africa and 25 times higher than that in India.  Though Third World countries account for a relatively small proportion of industrial CO2, they produce practically all of the CO2 in the secondary category, generally resulting from the burning of vegetation to clear new land.  A study jointly sponsored by the World Meteorological Organization and the United Nations Environment Program shows that global warming is growing. It says that if current emission trends continue, the mean global temperatures may rise 3C by the end of the twenty-first century.  The potentially catastrophic consequences of climate changes have caused widespread cries for joint preventive policy to combat environmental pollution, concentration of greenhouse gases and ozone depletion.  Statesmen and scientists stress that responsibility for reducing emissions must be divided across the members of the international community. The share of responsibility may be remarkably different depending on industrial development, income, social structure and political orientation of a country.  There is great controversy over the extent to which each government must control the emissions produced by its local population, industry and agriculture. Возвратное местоимение себя после некоторых русских глаголов на  английский язык не переводится: Hefeelswell.  - Он чувствует себя хорошо. He behaved like a child. - Он вел себя как ребенок. Но: Behave yourself!  - Веди себя хорошо! Не is not feeling himself.  -  Он не в своей тарелке. Английские возвратные местоимения часто соответствуют окончанию - ся/-сь русских возвратных глаголов (сокращенное «себя»): защищаться, оказаться, развлекаться, веселиться. Напримep: The soldiers tried to defend themselves.  - Солдаты пытались защищаться. She found herself in hospital.   - Она оказалась в больнице. We enjoyed ourselves greatly.  - Мы здорово повеселились.
