Топик по английскому языку "Экологические проблемы"

In the beginning it is necessary to tell some words about the concept ecology.

The ecology was born as purely biological science about relationship an organism - Wednesday. However with strengthening of anthropogenous and technogenic pressure upon environment became obvious insufficiency of such approach. After all there are no phenomena, processes and territories, unaffected this powerful pressure now. Also there is no science which could be eliminated from searches of an exit from ecological crisis. The circle of the sciences involved in an ecological perspective extraordinary extended.

 Nowadays along with biology it is economic and geographical sciences, medical and sociological researches, physics of the atmosphere and the mathematician and many other sciences. Environmental problems of the present on the scales can be conditionally divided on local, regional and global and demand for the solution of unequal cures and scientific development, various on character. Example of a local environmental problem - the plant dumping without cleaning to the river the promstok, unhealthy people. It is violation of the law. Bodies of conservation or even the public have to fine such plant through court and under the threat of closing to force it to build treatment facilities. Special science thus it isnt required. Kuzbass - the hollow which is almost closed mountains filled with gases of coke furnaces and smokes of the metallurgical giant of which catching at construction nobody thought, or the drying Aral Sea with sharp deterioration of an ecological situation on all its periphery, or a high-level radioactivity of soils in the areas adjacent to Chernobyl can be an example of regional environmental problems. For the solution of such problems scientific researches are already necessary. In the first case - development of rational methods of absorption of smoke and gas aerosols, in the second - exact hydrological researches for development of recommendations about increase in a drain to the Aral Sea, in the third - clarification of influence on health of the population of long influence of weak doses of radiation and development of methods of deactivation of soils. Still in the infinite Universe on an orbit round the Sun it is unceasing small mother Earth rotates, each new round as if proving firmness of the existence.

 The planet face is reflected incessantly by the satellites sending space information to Earth. But this face it is irreversible changes. Anthropogenous impact on the nature reached such scales that there were problems of global character. And now we will pass to specific environmental problems.
