Environmental problems of lakes are similar to those of inland seas. First of all, the water bodies are negatively affected by the economic and industrial activities of people, since the water of the lakes is used for various needs, and it goes down into the water bodies dirty, practically not cleaned. This leads not only to water pollution, but also to a change in the thermal regime of the ecosystem. Many living creatures of lakes are very sensitive to temperature changes and cannot exist normally. There is also the problem of turbidity of the water of the lakes, which also leads to discomfort for the inhabitants of the lakes. In general, any impact negatively affects the water area.
The following problems of lakes can be distinguished
Pollution of lakes occurs not only due to water runoff, but also due to pollution of nearby landscapes. Atmospheric pollution also causes significant damage. During precipitation, all pollutants enter water bodies, worsening the condition of ecosystems. There is also another environmental problem the saturation of water bodies with biogenic elements. It should be noted that each lake has its own set of problems.
