Dostinction between eutrophication and artificial eutrophication

Eutrophication is having waters prosperous in mineral as well as organic nutrients that promote a proliferation of plant life, especially algae, which reduces the dissolved oxygen substance and frequently causes the extinction of other organisms.

Eutrophication is an increase in the concentration of chemical nutrients in an ecosystem to an extent that increases the primary productivity of the ecosystem. Depending on the degree of eutrophication, subsequent negative environmental effects such as anoxia and severe reductions in water quality, fish, and other animal populations may occur. Cultural eutrophication refers to such problems when caused by man's everyday activities. The eutrophication of the Potomac River would be an example. Most people worry about contaminated sediments in water.

However, natural sediments form by weathering of rock. They then erode from the site of weathering and are transported by wind, water or ice operating under the influence of gravity. This is a normal ongoing process and not detrimental to ecosystems.
