kirill [66]

The biodiversity will decrease due to an increase in pollution is the effect will have on the biodiversity on the river ecosystem.

The inclusion of the polluted sewage of the surrounding area into the river directly mixes several chemicals to the water, which are potentially harmful for all the animals living there. This leads to destruction of the flora and fauna of both water and lands surrounding them. This hampers the biodiversity of the water as well as surrounding land.
