Water Pollution
Environments are inalienably liked to our life, but these days, environment preservation is becoming more and more important since environmental disregard can lead many social problems such as pollution, exhaustion of resources. Hence, many organizations are struggling against environment contamination. If the environments go bad, we suffer from polluted air and degraded water.
Here, we want to deal with water pollution – one of the main problems in earth.
WATER POLLUTION CAUSES - #1Oil, Gasoline and Additives
Oil spills like the Exxon Valdez spill off the coast of Alaska or the more recent Prestige spill off the coast of Spain get lots of news coverage, and indeed they do cause major water pollution and problems for local wildlife, fishermen, and coastal businesses. But the problem of oil polluting water goes far beyond catastrophic oil spills. Land-based petroleum pollution is carried into waterways by rainwater runoff. This includes drips of oil, fuel, and fluid from cars and truck; dribbles of gasoline spilled onto the ground at the filling station; and drips from industrial machinery. These sources and more combine to provide a continual feed of petroleum pollution to all of the world’s waters, imparting an amount of oil to the oceans every year that is more than 5 times greater than the Valdez spill.
WATER POLLUTION CAUSES - #2Chemical and Industrial Processes
Almost all bodies of water in the world have some level of pollution from chemicals and industrial waste.
In the United States, 34 billion liters per year (60%) of the most hazardous liquid waste – solvents, heavy metals, and radioactive materials – is injected directly into deep groundwater via thousands of “injection wells”. Although the EPA requires that these effluents be injected below the deepest source of drinking water, some pollutants have already entered underground water supplies in Florida, Texas, Ohio, and Oklahoma.
The US is not alone in careless treatment of its groundwater. In the late 1990s, India’s Central Pollution Control Board found that groundwater was unfit for drinking in all 22 major industrial zones it surveyed.
WATER POLLUTION CAUSES - #3Plastic
Plastics and other plastic – like substances (such as nylon from fishing nets and lines) can entangle fish, sea turtles, and marine mammals, causing pain, injury, and even death. Plastic that has broken down into micro – particles is now being ingested by tiny marine organisms and is moving up the marine food chain.
Sea creatures that are killed by plastic readily decompose. The plastic does not – it remains in the ecosystem to kill again and again.
GLOWING REVIEWS – NOT!
Even nuclear energy is among the causes of water pollution. Radioactive water pollution has a number of sources.
How to reduce the water pollution'
We can
No waste water – Try to consume less water and reimburse the water to the ground which is consumed.
Reduce the amount of detergent – Using detergent is one of the main reasons of water pollution.
These are small things. But every small thing can help as environmental protection is our utmost concern.
