Its a very disappointing statistics – Water, which covers 70% of the Earth’s surface is slowly getting into the category of ‘endangered species’.Once pristine bodies of water have been annihilated and infected beyond recognition by the human species.Sewage and fertilizer conduits are dumping nitrates and phosphates into our lakes and rivers – leading to an unmanageable growth of plants and algae. These parasitic plants suck up all the available oxygen and also clog up the waterways.This bio-cycle leaves little room for other flora and fauna in the water system.
Petroleum pollution comes in the form of oil spills. Apart from the oil tankers, off-shore drilling operations contribute a large share of pollution. One estimate is that one ton of oil is spilled for every million tons of oil transported. This is equal to about 0.0001 percent. Radioactive substances are produced in the form of waste from nuclear power plants, and from the industrial, medical, and scientific use of radioactive materials. Specific forms of waste are uranium and thorium mining and refining.
Municipal, Industrial and agricultural wastes also contribute in a herculean way to the water pollution menace. These effluents have the potential to dissolve into the water table and lingers for a prolong period of time. So, while the water is getting dried up from all it’s natural reservoirs, the underground and terrestrial water pollution is continuing unabated.
