Did you know:

  • If just 25% of U.S. families used 10 fewer plastic bags a month, we would save over 2.5 billion bags a year.
  • Every year we throw away 24 million tons of leaves and grass. Leaves alone account for 75% of our solid waste in the fall.
  • Over 100 pesticide ingredients are suspected to cause birth defects, cancer, and gene mutations.
  • Every ton of recycled office paper saves 380 gallons of oil.
  • About 1% of U.S. landfill space is full of disposable diapers, which take 500 years to decompose.
  • Glass produced from recycled glass instead of raw materials reduces related air pollution by 20%, and water pollution by 50%.
  • Homeowners use up to 10 times more toxic chemicals per acre than farmers.
  • By turning down your central heating thermostat one degree, fuel consumption is cut by as much as 10%.
  • One ton of carbon dioxide that is released in the air can be prevented by replacing every 75 watt light bulbs with energy efficient bulbs.
  • The uncontrolled fishing that is allowed has reduced the amount of commercial species. Some species, up to one-tenth of their original population.
  • Already over half of the world's tropical forests have been lost.
  • The garbage in a landfill stays for a for about 30 years.
  • Every ton of paper that is recycled saves 17 trees.
  • Earth is 2/3 water. but all the fresh water streams only represent one hundredth of one percent.
  • 84% of all household waste can be recycled.
  • Computers pose an environmental threat because much of the material that makes them up is hazardous. A typical monitor contains 4-5 pounds of lead.
  • One gallon of motor oil can contaminate up to 2 million gallons of water.
  • Agriculture absorbs 74% of all water taken by humans from rivers, lakes, aquifers and wetlands against 18% for industry and 8% for municipalities.

Main Causes of Water Pollution

Main Causes of Water Pollution

Today, the world is facing one of the most serious problems of humanity and other forms of life, pollution. It is a known fact that pollution is very rampant all over the globe. Just look around and you will see rivers, lakes, beaches that are murky, stinky, and lifeless. Plastic, empty cans, bottles, and other trash have replaced the fishes and other wonderful marine creatures that used to reside under water. Yet, when scarcity arises and when epidemics occur many point their fingers to others and turn their backs from the responsibility. But in fact there is no one else to blame but the people. Man is the main cause of water pollution.

People pollute the water with chemicals and other hazardous materials. People have no regard to water – their source of life. They do not realize that this once abundant resource is rapidly being contaminated due to their negligence and carelessness.

Waste disposal has always been a chronic problem, not only because of the quantity of wastes, but because of its kind and the inadequate provision for a good system and technology to address the problem. There are many sources of water pollution but it is not the source that is really causing the problem but the improper disposal of the pollutants. People resort to careless disposal because it is cheaper, more advantageous, or simply convenient to them.

When you are taking a bath using your favorite shampoo or whenever you wash your laundry using no other than the best detergent in town, it is certain that before buying those products you really never consider asking yourself whether their contents can harm the environment or not. What mattered more was the scent and softness of your hair and the clean comfort of your clothes. Instead of finding an environmental friendly product, you simply chose convenience and your satisfaction of meeting your interests. However, if you will support environmental friendly products and become more conscientious of how you can avoid contributing to water pollution, then the world has gotten rid of one polluter.

In the same way, if chemical factories are only equipped with better facilities that can release treated wastewater, there will be no harm done to the lakes or rivers where they dump their by products. If home owners associations will work to build and provide their subdivisions with sewage treatment facilities, eutrophication can be controlled and dying bodies of water will be spared. But as mentioned, polluters choose the easier way where they can save on operation costs and where they can rid themselves of the hassles of responsibility. Anyway, they are not affected by the effects of their misdeeds.

Aside from improper and careless waste disposal, another main cause of water pollution is toxic substances coming from industrial, agricultural and domestic use. Trace elements of lead, cadmium, mercury, dioxins are detected in different water sources which sometimes accumulate in the water supply causing health problems. These toxic substances come from industries such mining, power plants, automobile manufacturers and others that produce toxic substances leading to bodies of water. Apart from these industries, these toxic materials contaminate the water through accidents like chemical or oil spills.

One more main cause of water pollution is the presence of excessive nutrients in the water. Nitrogen and phosphorous compounds that generally come from sewage, fertilizers, and animal manure are good food sources of algae. Excess nutrients in water also result to excessive growth of algae that deprive aquatic plants and animals adequate levels of oxygen to survive. Because of this many aquatic organisms die and decay which aggravates the problem.

Lastly, another considerable main cause of water pollution is sedimentation. Although it is hard to imagine how soil particles can contribute to water pollution, but it does. When huge amount of solid particles accumulate in water, whether due to deforestation, farming, or soil erosion, the sediments cloud the spawning grounds of fishes leading to their gradual extinction.

Humans greatly affect the environment. People will either be heroes or villains of Mother Nature. Toxic substances, algal bloom, sedimentation are all end results of human activities. These pollutants are not the real evils of water pollution but the people behind every wrong disposal and negligence. Unless man realizes that it is not the prohibition of pollutants nor banning industrial productions that should be changed but the behavior and attitude he possesses towards his environment, the rivers, lakes, and other water systems have no hope to be saved.
