There are many environmental problems caused by human but not widely known. One of them is eutrophication. This phenomenon cannot be entirely characterised as water pollution, as it mostly describes the process of too many plants growing in lakes, rivers and sometimes in the sea.

When household and industrial wastes are disposed into the water, they increase the quantity of germs in it. Germs threaten the health of the organisms living in the water, drinking it or feeding on organisms that live in it. Moreover, huge quantities of nitric and phosphoric salts enter the ecosystem. Phytoplankton, the tiniest sea organisms that can photosynthesize and depend highly on those salts, start to grow in population at top speed, consuming oxygen. As a result, zooplankton which feeds on phytoplankton starts to increase in numbers, again consuming oxygen and producing carbon dioxide.
