Environmental problems. Экологические проблемы

Environmental problem - the change of the environment as a result of human activities, leading to disruption of the structure and functioning of nature. Environmental issue is determined by the change in the properties of landscapes, and the degree of its manifestation can be characterized by intensity and area of distribution of these changes, and the nature of the properties (attributes) of individual issues: the degree of manifestation environmental problem The degree of change natural characteristics of the landscape, in% weakless than 10 average10-50 strong> 50

Water pollution - changing the chemical and physical condition and biological characteristics of water, limiting its further use. Air pollution - any adverse change in the composition of Earth's atmosphere as a consequence of it different gases, water vapor and particulate matter (due to natural processes or human activities).

Pollution - the kind of human degradation, in which the chemical content in the soils subjected to anthropogenic impact, exceeding the regional natural background level of their content in the soils.

Endangered species - is species that are at risk of extinction because of the small number of critical or exposure to certain environmental factors. Sakhalin musk. white Tiger Przewalski's horse
