There are many kinds of pollution. Water pollution reduces the amount of fresh water that is availiable for drinking and even activities like swimming. The pollutants that affect water come mainlhy from industries, farms and sewage systems.
Industries dump large amounts of waste products into bodies of water each year. Some of the waste includes chemicals and hundreds of other substances.
The farm waste includes animal waste, fertilizers and pesticides. These materials drain off farm fields into nearby bodies of water.
Sewage systems carry waste from homes, offices and industries into water.
Almost all cities have waste treatment plants that remove some of the most harmful waste from sewage but even treated sewage contains material that harms water.
The Natural Cycle of waste being turned into useful or at least harmless substances can break down easily if we pour too much waste into the water. The bacteria that works to decay the waste uses up too much oxygen during the decaying process. And as a result, less oxygen is available for the animals and plants in the water. Then the plants and animals die, which only adds more waste to the water.
Another major pollutant is oil. Oil enters oceans primarily as a result of oil tanker accidents. Such spills ruin beaches and kill birds or marine life.
Our desire for convenience is another cause of pollution. Many synthetic materials that pollute the environment were developed to save people time, work or money. Just as prevention of pollution is often considered too expensive, it is often considered too inconvenient.
Water pollution reduces the amount of purity and freshness to the water that is available for drinking, cleaning and for such activities as swimming and fishin. Industries dump huge amounts of waste into bodies of water each year. The waste includes chemical waste from animal and plant matter and hundreds of other substances. The pollutants that affect water come mainly from industries, farms and the sewage system. The sewage systems carry waste from homes, offices and industries into the water. Almost all cities have a waste treatment plant that removes some of the most harmful waste from the sewage. But even most of the treated sewage contains materials that harm the water.
