Anthropogenic factors of the aquatic environment.

Anthropogenic factors are all factors that a person has on nature. Most often they have negative consequences, although they can contribute to nature conservation (for example, the creation of reserves).
The anthropogenic factors of the aquatic environment include: the creation of reservoirs (sometimes this can lead to the disappearance of several species of fish, as, for example, the sturgeons disappeared after the construction of the Kuibyshev reservoir); discharge of waste into water bodies (water pollution with heavy metals, etc.), drainage of lakes and swamps; catch of fish and many others.
