When people start discussing the poor quality of water systems many people think of underdeveloped countries that do not have an extensive water system built but environmentalists continue to fight and advocate for better water regulations. Water pollution is cause manly human activities such as industrial production and dumping of waste. Many places around the world do not have proper water systems and regulations because of things like war and underdevelopment. “Water covers over 70% of the Earth’s surface. It is a very important resource for people and the environment. Water pollution affects drinking water, rivers, lakes and oceans all over the world. In many developing countries, it is usually a leading cause of death, by people drinking from polluted water sources” (Eschool, 2016).Physical and Biological DescriptionsThe effect of water pollution can be harmful or catastrophic depending on the kind of chemical, concentration of the pollutant and where there polluted. Many bodies of water near urban areas are highly polluted. This is the result of abiotic factors such as both garbage dumped by individuals and dangerous chemicals legally or illegally dumped by manufacturing industries, hospitals, and schools. One factor that is greatly affected by water pollution is the oxygen content. The oxygen content of the water can be reduced greatly if it is being polluted by an organic source, such as sewage. The amount of dissolved oxygen usually determines the number and types of organisms living in that body of water. For example, trout are sensitive to low dissolved oxygen levels and cannot survive in warm, slow-moving rivers or streams. Dead organic material in the water such as untreated sewage can reduce dissolved oxygen concentration. Another important abiotic factor that is affected by the pollution of water is temperature.(Eschool, 2016) If there was cooling water that entered some body of water, that water would act as a thermal pollutant and have negative effect on the members of that specific ecosystem.History of Human InteractionThe industrial revolution of the mid-19th century, greatly affected environmental movements across the globe. In the early stages of the movement were victories such as the Clean Air Act (1970) and the Clean Water Act (1972). “For centuries, humans unknowingly contaminated sources of drinking water with raw sewage, which led to diseases such as cholera and typhoid. According to a CNN report, one gram of human excrement contains approximately “10 million viruses, 1 million bacteria, 1,000 parasite cysts and 100 parasite eggs.” Today, over 1 billion people worldwide lack access to safe water and every 15 seconds somewhere on the planet, a child dies from a water-related disease, according to Water Partners International (www.water.org)”.(History, 2009). Water pollution is a serious issue that humans have continued to push to the side. Although humans have greatly contributed to the destruction of clean water, there are many groups that continue to fight for the basic human right of clean water. Current Problems One of the larger and more current problem of water pollution is Flint, Michigan crisis. We have seen in the news for the last few months the disheartening stories told by the people of flint communities. In 2013, the city of Flint changed their water supply and the community immediately recognized the issues that were ahead. Flint being a majority black city with high poverty rates turned this crisis into a racial issue. The black community started complaining to state and city authorities about the terrible water qualities and began to report illnesses cause by the pollution. Flint began getting water from Flint River to save money for the city. Residents started to complain which were later found to be E.coli and Coliform bacteria in the water supply. Solutions to Problems A large scale issue like the Flint water crisis cannot be fixed with a bandage like politicians usually do with all their problems. A solution would be an entire reconstruction of Flint water system no matter the cost. Saving a few dollars can cost a child’s life. Flint needs to implement tracking and regulation systems that allow environmental organizations access to the information. I think the city of Flint needs to compensate the communities effected by their mistake. Many of the ill are children that tested positive for lead poisoning and should have their medical and treatments paid by the state. As a global issue water pollution can be prevented by things like composting, not throwing chemicals or waste in your water systems, and making sure your government’s policies that help prevent water pollution. If not, take action and write to your politicians.
