Causes of water pollution .
Water pollution is the action of environmental contamination with man-made waste into water. The source of this waste could be raw sewage, chemicals, trash, or fertilizer. Water polltuion has severe human consequences, since less than 3% of the Earth contains water that is potable or safe for drinking. Also, water is so important for human survival because we cannot live without it. When a source for drinking water becomes cantaminated with untreated sewage it is possible to spread diseases through the water like Giardiasis, a diarrheal disease caused by a parasitic protazoa, Giardia lamblia. These types of diseases can also be caused by bacteria, viruses, and other microorganisms. Another type of water pollution usually occurs when water is contaminted with fertilizer. The water is then nitrified and phosphorolized by the fertilizer chemicals. These added nutrients in the water can cause eutrophication or the process of changing of a body water due to excessive plant nutrients. This eutrophication promotes excessive growth of algae and aquatic plants, which then chokes the open-water areas, thus decreasing the amount of oxygen available in the water. Consequently, fish and other organism may die off due to the lack of oxygen. Other types of water polltion include trash that is dumped into a body of water or chemicals that seep or are dumped into a body of water. These two types of water pollution can have harmful side effects for humans and different organisms.
