Algal blooms. Aerial photograph of the river Grosser Ostersee, Germany with, algal blooms lining the shores (light green). The blooms are caused by phytoplankton, microscopic plants.

Contamination by sewage or fertilisers can increase the water's mineral content, which accelerates the growth of all plants, particularly aquatic algae.
