Effects of water pollution


Most water pollution doesn’t begin in the water itself. Take the oceans: around 80 percent of ocean pollution enters our seas from the land. Virtually any human activity can have an effect on the quality of our water environment. When farmers fertilize the fields, the chemicals they use are gradually washed by rain into the groundwater or surface waters nearby. Sometimes the causes of water pollution are quite surprising. Chemicals released by smokestacks (chimneys) can enter the atmosphere and then fall back to earth as rain, entering seas, rivers, and lakes and causing water pollution. That’s called atmospheric deposition. Water pollution has many different causes and this is one of the reasons why it is such a difficult problem to solve. Water borne diseases; like cholera and jaundice; are on the rise because of water pollution.
