ecology

Scientists estimate that today humanity is living at the experience expense of next future generations, which will have to live in worse life living conditions, and that fact will unavoidably affect on health and social safety. To avoid that, people must to learn how to derive income from a capital stock, but not spending that capital itself. Since the XX century this capital have been spent in greater quantities with growing amount, and for now, the Earth has changed so much that for several decades global ecological problems are being have been discussed on international level. In the current ecosystem, even new technologies of balanced environmental management don't save biodiversity. For that goal, specialty protected natural sites(SPNS) are necessary, where agricultural business is strongly prohibited. In Russia SPNS space is over 20 times lower than that of in developed countries. For saving flora and fauna of our country, it is necessary to increase the space of SPNS at least in 10-15 times. Basic reasons for global ecological troubles were demographic explosion and technological revolution at the same time.
An object of work is to examine ecological problems and solution approaches.
A The population of the Earth in 1950 was 2.5 billion people, then in 1984 doubled and will be equal 6.1 billion in 2000. Geographical growth of the Earth population is not steady. Russia's population has been declining form 1993, but growing in China, southern Asia, Africa and Latin America. According to that growth, spaces that humanity took from nature for under cultivation lands, living and social buildings, rail and motor-roads, airports and sea ports, gardens and dumps have grown in 2.5-3 times for past half a century. At the same time, a technological revolution has given humanity the possession of atomic power possession, which among other benefits has a resulted in radioactive pollution of large areas.
The number of automobiles that pollute city's atmosphere grew in has grown a dozen times what is was.
Besides of applying manure, poisons or so-called pesticides were widely applied as a result surface layer global ocean was polluted. All this brought us to large environmental problems. Global environmental problems is a fair result of a reaction between our civilization and environment at the period of industrial development.
