Sulfur dioxide and nitrogenous oxide released from industries and power plants infiltrate river ways by acidic rainfall. Sewerage and effluent are released into rivers in some regions. Pollution can decrease the pH of the water, attacking all organisms from algae to vertebrates. Biodiversity reduces with reducing pH.
We impact rivers and streams by fishing because we are taking animals which is part of an enviornment. we also damage it by trash or litter. oil spills and such too can contaminate water for ppl and animals to drink, therefore spreading diseases.
