How water gets polluted? Is food chain affected in the process?

1.	How water gets polluted? Is food chain affected in the process?
Answer» Various causes of water pollution: • Industrial waste • Sewage and waste water • Mining activities • Marine dumping • Accidental oil leakage • The burning of fossil fuels • Chemical fertilizers and pesticides • Leakage from sewer lines. • Leakage from underground storage tanks for liquids like gasoline. • Contamination of water causes disruptions of food chains and destruction of ecosystems. A deadly by product of this water pollution is the spread of water- borne diseases such as cholera, typhoid etc. Pollutants such as lead and cadmium are eaten by tiny animals. Later, these animals are consumed by fish and shellfish, and the food chain continues to be disrupted at all higher levels. Eventually, humans are affected by this process, too.
