What is Eutrophication?
'''Eutrophication''' is what a [[water]]-based [[ecosystem]] does when too many [[Nutrient|nutrients]] are added to it. '''Eutrophication''' is mainly caused by two nutrients, [[phosphorus]] and [[nitrogen]]. These are normally brought to aquatic ecosystems as runoff from fertilized agricultural areas, [[erosion]] from river banks, river beds, clearing of land (deforestation), or [[sewage]] that ends up in aquatic environments. The major consequence of '''eutrophication''' are [[algal bloom|algal blooms]]. {{pollution}} [[Category:Water pollution]] [[Category:Environmental chemistry]] {{chem-stub}}
