This is due to discharge of environmental pollutants or effluents into water bodies without treatment. Water pollution affects the entire biosphere, including not only the individual species but also their natural biological communities. It results in the death of much of the aquatic life residing inside the contaminated water body. It also leads to various diseases like cholera, dysentery, diarrhea, malaria, dengue, chickingunia, etc. and even fatal in some cases if that water is consumed without treatment. .
