Industrial effluents are being discharged into the rivers and streams. The waters in the streams and rivers get contaminated and toxic. Water pollution affects agriculture in drastic ways. Water from these rivers is used to irrigate the fields. The crops are exposed to water containing chemicals, mercury, lead and arsenic dissolved in it. These pollutants enter into food grains, vegetable, and fodder, turning the crops into unhealthy, poisonous crops.
