This will lead to a lack of potable water, contamination of the food chain, destruction of biodiversity, and many more.
The destruction of biodiversity can be caused by the increasing the unbridled growth of phytoplankton, eutrophication process that will consume more oxygen and cause algal bloom and decrease the oxygen in the water and destroys the organism and natural food web.
