A study published by Cornell University maintains that about 40 percent of deaths in the world are caused by pollution.Drinking water is significantly affected by land pollution. About half the world’s population does not have access to safe drinking water, and water-based diseases cause up to 10 million deaths each year.Each year, Americans add 1.8 billion disposable diapers, 30 billion foam cups and 220 million tires to landfills.10 Water Pollution Facts for the U.S.Over two-thirds of U.S. estuaries and bays are severely degraded because of nitrogen and phosphorous pollution.Water quality reports indicate that 45% of U.S. streams, 47 percent of lakes, and 32 percent of bays are polluted.Forty percent of America’s rivers are too polluted for fishing, swimming or aquatic life. The lakes are even worse -- over 46% are too polluted for fishing, swimming, or aquatic life.Every year almost 25% of U.S. beaches are closed at least once because of water pollution.Americans use over 2.2 billion pounds of pesticides every year, which eventually washes into our rivers and lakes.Over 73 different kinds of pesticides have been found in U.S. groundwater that eventually ends up in our drinking water - unless it is?adequately filtered.The Mississippi River, which drains over 40 percent of the continental U.S., carries an estimated 1.5 million metric tons of nitrogen pollution into the Gulf of Mexico every year. This resulting pollution is the cause of a coastal dead zone the size of Massachusetts every summer.Septic systems are failing all around the country, causing untreated waste materials to flow freely into streams, rivers, and lakes.Over 1.2 trillion gallons of untreated sewage, groundwater, and industrial waste are discharged into U.S. waters annually.The 5-minute daily shower most Americans take uses more water than a typical person in a developing country uses in a whole day.10 Water Pollution Facts for Beyond the U.S.Pollution of surface water is a problem for over half of our planet’s population.

Children in polluted environments often carry about 1,000 parasitic worms in their bodies at any time.At any given time, half of the world’s hospital beds are occupied by patients with water-borne illnesses.Close to 85% of the total area of Bangladesh has contaminated groundwater, and the most dangerous contaminant is arsenic. Thus, 1.2 million people in this nation are exposed to the deadly effects of arsenic-contaminated water.Asian rivers are considered the most polluted in the world. They have three times as many bacteria from human waste as the global average and 20 times more lead than rivers in industrialized countries.In Ireland, about 30% of the rivers are polluted with fertilizers and sewage, which make them too polluted for swimming, fishing, or aquatic life.One of the most polluted rivers in the world is the King River in Australia. Over 1 million sea birds and 100,000 marine mammals and other creatures have died from the toxins and acidity in this river.The U.N. estimates that by 2025, forty-eight nations, with combined populations of 2.8 billion, will face freshwater scarcity. ................
