I think that environmental pollution - is the process of modifying the negative environment - air, water, soil - by her intoxication substances that threaten the survival of living organisms. Every year more and raises the issue of environmental pollution. This is something that does not bother people a hundred years ago. Now it is no longer taking care of individual cities or regions, and entire nations and continents. Pollute the atmosphere, water, soil and all that is called habitat. Pollution in the narrow sense is considered bringing in some fresh environment, not typical for her physical, chemical and biological agents or exceeding the average annual natural extent of these agents in the environment. Direct objects pollution (acceptors pollutants) are the main components of ecotope (biotic habitat associations): atmosphere, water, soil. Indirect object pollution (pollution victims) are components of the ecological community - plants, animals, micro-organisms. The scale of pollution may be divided into local, regional and global. These three types of pollution are closely linked with each other. As a rule, is the primary local pollution, which, if the rate of the contamination greater than the rate of natural purification, goes to a regional and then the accumulation of quantitative changes - global change in the properties of the environment. For global pollution more important is the time factor. Along with pollution fresh for her synthetic substances, large damage to nature and human health can cause interference in the natural cycle of matter through active industrial and agricultural activities, and in addition the generation of municipal waste. Forty percent of people in the world die due to pollution, but just water, soil and air. These environmental problems, coupled with rapid population growth leads to an increase in diseases … it catastrophically bad, that’s what I think.
