Planet earth is made up of over two-thirds of water and less than one-third of land. Having contaminated water, exposes us to significant health risks. Water pollution is caused by several different human activities that result in toxins, chemicals and waste in our water supply. A 1969 United Nations report defined ocean pollution as: "the introduction by man, directly or indirectly, of substances or energy into the marine environment (including estuaries) resulting in such deleterious effects as harm to living resources, hazards to human health, hindrance to marine activities, including fishing, impairment of quality for use of sea water and reduction of amenities."
There are several types of water pollutants; one category is the microbiological,

Fecal pollution threatens the quality of water and is spread by hospitals, slaughterhouses, livestock farms… The increasing pollution in water threatens its quality and quantity and the process to treat water results in an increase of water pricing. Exposure to fecal contaminated water can result in several diseases.
To investigate the polluted regions, a test was conducted by sampling 67 sites of Honghe River of china. The study was conducted to evaluate water quality based on the Honghe River located in Eastern China and was done within 15 days. The results of the experiment showed the water was exposed to many pollutants. According to the results of the research article by Plos, “among the 67 monitored sites, 18 were heavily polluted. Seven of the sites were medium polluted and 19 sites were slightly polluted. Only 5 monitored sites resulted in non polluted

Inorganic mercury is a result of many industrial processes and has caused fish to be dangerous from a high level of mercury to kids and pregnant women. Phosphorous runoff is also produced by industries and can get into waterways, which has led to shellfish poisoning in humans. All of these pollutants have been found in water bodies and might be the biggest threat to the public’s health by water.
Water pollution affects other species and their environment just as much. When contamination raises the water temperature it sometimes forces fish and other organisms to relocate. Contamination in the water is highly dangerous for the lives depending in these water bodies; it harms the organisms and can disrupt food chains. Water pollution threatens aquatic life and increases the amount of air pollution by
Do you ever feel like there is a piece of dry, and scratchy piece of sandpaper in the back of your throat from not having enough water? How would you feel if you could never stop the anoying feeling, that is constantly reminding you, that you could die from extreme thirst any day from now. The main reasons that China was driven into the intense water shortage is, their Government policies, Population increases and the most tremendous reason is the industrialization of China. One of the main reasons that is driving China's unfortunate water crisis is, China’s tremendous population growth. As China’s cities are increasing in population more of their residence are consuming their limited water supply.
Drinking contaminated water can cause different types of cancers and also infertility and birth defects due to of the presence hazardous chemicals. Impoundments that have not been built or properly closed off have led to the death of many animals and also health issues in
“These water bodies supply our drinking water, water for agriculture and manufacturing, offer opportunities for recreation and provide habitat to numerous plants and animals.” Pollution is degrading our waters and one of the best forms to study the change in water quality is testing contaminants in fish that inhabit
Humans can cause ocean pollution when they dump sewage in the ocean or on the beach (Doc. 2). The pollution that is put in the ocean will not only affect the ocean animals but can also affect humans (Doc. 2). When a fish eats plastic or garbage it becomes toxic (Doc. 2). If a person eats that toxic fish they will be very sick
If the fish are not healthy, that can adversely affect people. People could eat contaminated fish, or people cannot sell the fish because they are contaminated. Some fish may die from the pollution, leading to less fish for catching. Lower populations of fish and other marine life can also cause an imbalance in the food chain. Predators can also be harmed
The water pollution is polluting great deal of their rivers. The reason for a mass of this is “Industrial runoff, poor sewage treatment , and catch basins”(Auslin). All of this is making the water of china is deadly for people to drink and to swim in. A group did a study in 2011 that said “39 percent of china’s seven river basins were too polluted for general use, including 14 percent that were unfit even for industrial use. In 26 key lakes and reservoirs, only 42 percent of total water was deemed fit for swimming and fishing, while 8 percent was unfit even for industrial use”(Auslin).
Many people have wondered why China's water scarcity is getting worse. It is because Global warming, Water pollution and the most important is Industrialization. North China is suffering the most. This means it does not have enough fresh water to meet its needs. The North's lack of water will now put the whole city in danger.
People complain about pollution from factories, cars, global warming, and the melting of polar ice caps, yet many people disregard the dangerous that come with fracking. Fracking is the process of injecting liquid at high pressure into subterranean rocks, and/or boreholes to force open existing fissures and extract oil or gas. Fracking is causing an epidemic economically and environmentally. Fracking is continuously destroying the earth day by day. From the endless fracking today’s economy is depleting.
About 71 percent of our planet Earth is covered by water, and the majority comes from the oceans (about 96.5 percent of all Earth’s water). It remains as the most expansive, diverse, and mysterious places on planet Earth. But it is being threatened by the pollution by people and nature itself. By polluting the habitat of marine organism will indirectly affect the ecosystem of the marine life. Marine life is dying and as the result the oceanic ecosystem is threatened.
Water Pollution is a huge environmental problem that has serious effects on marine habitats, animals, and water quality. BP1: The world's marine habitat has been getting worse because of how bad the pollution has gotten. “ Over 80% of marine pollution comes from land based activities “ (source 5 ). This quote explains how most of the water pollution is caused by human activity. “ Plastic litter does not degrade, can be expected to last in the oceans for hundreds of years “ ( source 6 ).
MAJOR PROBLEM: SINGAPORE WATER SHORTAGE ISSUE Short history of Singapore: Singapore gained independence on 9th August in 1965 from the merger with Malaysia. After its separation from Malaysia, Singapore faces major problem in many areas. Singapore is a small island of area size of 718.3km square. Given her limited land capacity, Singapore face a severe lack of natural resources such as water. In the ’60s and ’70s, Singapore was heavily reliant on imported water from Malaysia and faced urbanisation challenges such as polluted rivers, water shortages and widespread flooding.
Compared to the rural river water, and urban river water was polluted more seriously, urbanization and urban activities had a significant negative impact on the river water quality (Ouyang, et al., 2006 .).Additionally the rapid urbanization caused a series of changes to the river systems and brought about water degradation in the tuna region in china (Deng, et al., 2015). A practical feature of the urbanization process, including the release of domestic sewage and others in water resources causes changes that may impair the
Marine pollution such as presence of organic matter in the ocean can result in the condition known as hypoxia or oxygen depletion and this can have adverse effect on the marine life including plant and animals and fish. Death of these fish can result in loss of millions of US dollars that are generate from the fishing industry. Marine pollution can also result in presence of foul smell resulting from the decomposing sewage being directed to the ocean and this has the effects to hinder recreational activities taking place in the sea as well as cause discomfort and breathing problem to the surrounding population (Laura, 11).marine pollution can also result in danger to human health. The human swimmers and water sport lovers can become endangered by swimming in the polluted marine waters (Laura,
LITERATURE REVIEW What is water pollution? As the country is becoming more and more populated, the demands for social services have increased significantly. This has led to an increase of the pollution in many developing towns such as Ga-kgapane. The most disturbing and problematic forms of pollution in Ga-kgapane is the pollution of the natural streams. Water pollution is when there is a build of one or more substances in water to such an extent that it causes problems for animals or plants.
Water is the most important component found on the surface of the earth because it is source of life for living creatures. However, water pollution has become a global concern. Water pollution can have several forms from diverse sources. It is expected that there will be a lack of clean water in next few decades due to pollution. Nile river water in Egypt is the focus of attention of many studies due to many reasons.
