$\huge \mathbb\fcolorbox{pink}{pink}{Answer}$

Industrial wastes: Many industries dispose waste into rivers and streams. These chemicals are poisonous and contaminate water.

If large amounts of fertilizers or farm waste drain into a river the concentration of nitrate and phosphate in the water increases considerably. Algae use these substances to grow and multiply rapidly turning the water green. This massive growth of algae, called eutrophication, leads to pollution.
