Water Pollution and Its Effects on the Environment
Water is probably the most important resource we as people have. Humans can survive without food for several weeks, but without water we would die in less than a week. On a slightly less dramatic note, millions of liters of water are needed every day worldwide for washing, irrigating crops, and cooling industrial processes, not to mention leisure industries such as swimming pools and water-sports centers. Despite our dependence on water, we use it as a dumping ground for all sorts of waste, and do very little to protect the water supplies we have.
Water pollution is starting all over the world. Water pollution occurs when waste products or other substances, such as microorganisms,

Exhaust from cars and factories, and chemicals like pesticides are carried into the atmosphere through vaporization. When it rains, many of these chemicals fall into the ocean. H.L. Windom says, "Up to 25% of the annual DDT production was rained out into the worlds oceans." One of the most harmful pollutants is oil. Gallons and gallons of oil are dumped, leaked, or seeped into the ocean each year. Contaminating the oceans will damage every living thing in one way or another. Deadly chemicals and radioactive materials get into the oceans and cause serious damages. One of the most deadly of all the toxins that enter the ocean is oil. According to the Worldwatch institute, "Low-level oil contamination can kill larvae and cause disease in marine life." The oil can coat marine animals and cause death. Many animals also ingest the oil. Marine life is effected by all of the pollutants, not just oil. For instance plastics are also a big killer of marine life. Researcher, Peter Weber, claims that, "Plastics entangle marine life or is mistaken as food." According to Dwight Holing, "Areas with chemical contamination, fish and shellfish have developed genetic defects such as chemical burns and tumors, and bottom-dwellers are showing fin erosion and cancer." Farming and mining all contribute to the dumping of sediment into the ocean. Peter Weber states, "Sediments that make their way into the ocean can cloud the water and prevent photosynthesis, clog the gills of fish, and
