Approximately 360 million km on the surface of the planet is water in the form of oceans or rivers. Unfortunately, it’s these waters that are frequently the target of pollution, with adverse effects on marine life.
Oceans are tied to land through the rivers, which transmit the water pollution. Chemical substances infiltrate into the earth and then into the waters of the rivers. Chemical substances like oils, fertilizers, insecticides and herbicides which don’t decompose in contact with the earth but eventually reach the oceans.
Waters thus become immense deposits for these types of toxic pollution. A recent water pollution statistic says that 65% of pollutants are coming from rivers. 20% of these are from British rivers, 25% of water pollution comes from air pollution, 7% from chemicals dumped into water and the rest come from water pollution by ships.
In water pollution incidents, there is almost always oil involved. The usual practice of washing oil tankers represents the equivalent of 8 to 20 million barrels of oil every year dumped into waters on purpose. Although this is a common practice, water pollution acts condemn it, and if they are caught in the act of washing the tanker, they can pay tremendous fines, and even go to prison.
