READING TASK. Read the text and write all things that cause to air pollution.
As the first engines were created, people’s lives were changed dramatically. And only in some decades, when it became hard to breathe in big cities and when acid rains started to destroy forests. CO2, is not the most dangerous substance in the world. Just think about some chemicals which cannot be recycled by the Earth or it takes hundreds of years to do it. We live in the era of high-tech pollution. When we throw away old TV-sets, radios, computers, they just lie in piles somewhere not far from cities. They cannot dissolve, evaporate or rot. If to start to destroy them, for instance, to incinerate them, it could cause even more problems: very often these substances are poisonous. It seems to be a situation without way-out! We can’t stop producing technological devices, but when they are obsolete, we don’t know how to destroy them. When speaking about environmental problems it’s impossible not to mention deforest¬ation. It passes my understanding why people are doing it. Now, when every tree must be sacred due to its ability to absorb carbon dioxide, people are cutting down large areas of rainforests, sometimes burning them. Animals are also victims of man’s impact on the planet. As T have already mentioned they can die because of deforestation or global warming. But they can also be killed on purpose. Poachers kill whales, fish, elephants, snakes for money and these people are not in the least worried about ecological balance or natural heritage.
WRITING TASK. Write an opinion essay on the topic “Ecology”.
Since ancient times Nature has served Man, being the source of his life. For thousands of years people lived in harmony with environment and it seemed to them that natural riches were unlimited. But with the development of civilization man's interference in nature began to increase. Large cities with thousands of smoky industrial enterprises appear all over the world today. The by-products of their activity pollute the air we breathe, the water we drink, the land we grow grain and vegetables on. Every year world industry pollutes the atmosphere with about 1000 million tons of dust and other harmful substances. Many cities suffer from smog. Vast forests are cut and burn in fire. Their disappearance upsets the oxygen balance. As a result some rare species of animals, birds, fish and plants disappear forever, a number of rivers and lakes dry up. The pollution of air and the world's ocean, destruction of the ozone layer is the result of man's careless interaction with nature, a sign of the ecological crises. The most horrible ecological disaster befell Ukraine and its people after the Chernobyl tragedy in April 1986. About 18 percent of the territory of Belarus were also polluted with radioactive substances. A great damage has been done to the agriculture, forests and people's health. The consequences of this explosion at the atomic power-station are tragic for the Ukrainian, Belarussian and other nations. Environmental protection is of a universal concern. That is why serious measures to create a system of ecological security should be taken. Some progress has been already made in this direction. As many as 159 countries - members of the UNO - have set up environmental protection agencies. Numerous conferences have been held by these agencies to discuss problems facing ecologically poor regions including the Aral Sea, the South Urals, Kasbahs, Donbas, Semipalatinsk and Chernobyl. An international environmental research center has been set up on Lake Baikal. The international organization Greenpeace is also doing much to preserve the environment. But these are only the initial steps and they must be carried onward to protect nature, to save life on the planet not only for the sake of the present but also for the future generations.
