CAUSES OF WATER POLLUTION (versi Inggris)

Water pollution refers to changes in physical, biological, chemical and water body conditions that would disrupt the balance of the ecosystem.
Like other types of pollution, water pollution results when a large amount of waste that comes from various sources of pollutants can no longer be accommodated by natural ecosystems.Consequently, if the waste is not destroyed as fast as manufactured, they create other organisms that are not beneficial to humans and many. But that's not all. Learn more about what causes water pollution.
Actually there are specific reasons that are behind what causes water pollution. However, it is important to familiarize yourself with the two main categories of water pollution. Some pollution comes directly from one specific location. This type of pollution is called point source pollution such as sewage pipes contaminated water flowing into rivers and farmland. Meanwhile, non-point source pollution is pollution that comes from large areas such as gasoline and other dirt from the highway that goes into lakes and rivers.
What causes water pollution? Who causes that should be responsible for damages brought by their pollutants? How pollution sources contaminate different bodies of water?
One of the main causes of water pollution that has caused serious environmental health problems and is a pollutant that comes from chemical and industrial processes. When the factories and producers poured chemicals and animal waste directly into rivers and streams, the water becomes toxic and a low oxygen level causes many aquatic organisms die. These wastes include solvents and toxic substances. Most of the waste is not biodegradable. Power plants, paper mills, refineries, automobile factories dispose waste into the rivers.
The hot water from power plants is called thermal pollution. This kills aquatic animals and plants by reducing the oxygen content of water. Power plants use water to cool their engines, thus changing the water temperature.
Apart from thermal pollution, there are also organic and inorganic pollutants. Organic wastes include refuse from slaughter houses, fish and meat canning factories, and leather tanning companies, manufacturing plants, pesticides and oil companies. Since that decomposes organic waste by microorganisms, most of the oxygen dissolved in water use and discharge began to stink.
Inorganic waste including toxic and corrosive substances like acids, heavy metals, mercury, cadmium and lead which can disrupt normal body processes. Battery manufacturers, mining, paper mills increase the concentration of a hazardous and toxic mercury to things that are most alive.
Other causes of water pollution from pesticides. Agricultural pesticides poison aquatic plants and animals. animal manure, chemical fertilizer, phosphate detergent pollute water by providing excess nutrients. pollution is known as eutrophication. This greatly increases the growth of algae in water, thereby reducing the amount of oxygen levels in water causes the death of many aquatic organisms.
Water is also polluted by garbage specifically plastics and other plastic-like substance. Some plastics such as nylon fish and marine animals can involve others. Plastics that have broken up into small pieces to be eaten by sea creatures which can cause their death. Because the plastic is non-biodegradable, it will continue to kill more fish.
One cause more water pollution is derived from household waste.Because no one wants to live in polluted areas, near the dumpsite or landfill, waste water and untreated manure washed from the home polluting different bodies of water. Most developing countries practice this type of waste disposal. Even in developed countries perform poorly treated discharge to the canal causes the main body of water. The danger is when the sewage pipes were broken and dirty drinking water. When this happens, the damage would open a wide range of water-borne diseases that would cause danger to consumers.
Last pollution among the causes of water self-care and household products. Shampoo, lotions, moisturizers, hair dyes, bleach, detergent, fabric softener, and many others contribute to water pollution. Human waste is not the only one who went into the ditch.This product also joined the waste water pollutes rivers, streams, and lakes.
Although the world is full of water, only three percent were drinking.Included in 3% of drinking water source is a river, spring, river, lakes, and waterfalls are continually threatened and contaminated by various factors that cause water pollution. If the sources of water pollution are not controlled, these basic needs will eventually become a rare commodity that only a few are able to have.
