Different kinds of pollution

Water pollution 

is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater). This form ofenvironmental degradation occurs when pollutants are directly or indirectly discharged into water bodies without adequatetreatment to remove harmful compounds.

Water pollution affects the entire biosphere – plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and population, but also to the natural biological communities.
