Life cannot exist without water. The basis of everything living is water. About sixty percent of an adult human is made up of water and each day that person should intake at least six to eight glasses of water a day. If there was no water there would be nothing to drink to keep a body hydrated because every known liquid is made up of or contains water. A person can only survive three days without water. Only two and a half percent of the water on the earth is drinkable, which is a small percentage considering the amount of water on the earth and the size of the world and population.
Although water is important to survive it is not always safe. Presently, in the world there are 768 million people who do not have access to safe drinking water and another 2.5 billion people who do not have ideal sanitation conditions for their water supply. This causes many deaths each year, including countless deaths of children; each year about 700,000 children die from unsafe sanitation and drinking situations which averages out to around 2,000 children a day. Within the United States alone forty-four percent of streams, sixty-four percent of lakes, and thirty percent of bays are not clean enough for everyday activities like, swimming, fishing, and drinking. A majority of this pollution is caused by contamination of the water through chemicals, bacteria, and other pollutants humans introduce to it. Despite the fact that human existence depends on water, the main threat to the quality of it is the humans themselves.
Human activity is the main source of pollution in the body of waters today. Almost everything we do in society causes pollution which leaves so many different possibilities of ways to contaminate the most important resource. “Industrialization, production, agriculture, land-use practices, hydropower generation, fossil fuel and nuclear power generation, disposal of wastes, and our everlasting desire for consumption to obtain more, whether it be material objects, or material items is causing devastatingimpacts to our ecosystems, and water sources” (Human Impacts on Water Quality). These are only some of the types of pollution that are point source and can be identified, but not all can be identified.Overall, though the most important and significant are agricultural and industrialization.
Three important factors for water contamination when dealing with agricultural pollution are fertilizers, pesticides, and animal waste. All of these things can be found in a variety of places, including, but not limited to lawns, golf courses, farms, and fields. Almost everywhere you go with grass or plants growing you will find some form of fertilizers, pesticides, or animal waste. Although people may not think or realize that even though their water property is not located directly near water or they do not put the chemicals or waste near water it still affects it. Runoff plays a key role in water pollution especially with agricultural pollution because it...
