Thesis Statement

When you think of problems in the world today, water pollution isn’t one that would normally come up. In fact it is one of the worst problems in the world today. Water pollution, by definition, is the contamination of streams, lakes, underground water, bays, or oceans by any substances harmful to living things. All living things contain water and most need water to survive, so water pollution is a big problem. If severe, the pollution can kill off birds, fish, and any animals that use the water source. In some cases even killing an entire species.

The polluted water supply that results can become harmful to humans. Aquatic life quickly suffers the effects of watershed pollution.

Water pollution has become a huge factor in the crisis of earth contamination. It is defined as the addition of harmful chemicals to natural water. Sources of water pollution include industrial waste, marine dumping, global warming, oil pollution,

According to Ocean Crusaders, there is over 100,000 marine animals that die each year because of plastic bags. “Beaked whale species in particular are highly susceptible to swallowing plastic bags as they are believed to strongly resemble their target prey, squid,” Britannica Advocacy for Animals states. Animals do not know what a plastic bag is, and often mistaken them for food. When an animal ingests a plastic bag, the plastic bag will be stuck in the gut for a very long time, sometimes more than 1000 years! Also, food would not be able to go through the intestines anymore and would probable cause the animal to die slowly. Since a plastic bag takes around 1000 years to completely decompose, it means that by the time the animal decomposes, the plastic bag is still not fully decomposed and will be back in the ocean, ready to kill another animal. As you can tell, plastic bags are very harmful to animals, especially marine animals. When plastic bags are banned, there is no chance of it going into the ocean, and many animals will be saved.

Do you know that it will take 1000 years for a plastic bag to decompose? Our world is the most friendly planet for human beings and every other living thing. We should never take our planet for granted because there is no other like this one and in order for us to keep our planet safe and sound, we should get rid of plastic bags. The other most effective way to keep our planet safe is to recycle every plastic bottle that we used. Every plastic product should not be thrown to the garbage because plastic bottles will take several decades to decompose in soil.

Part One: Using what you have learned in English class, change the following topics into thesis statements. Remember: subject + the side of the argument + 3 main points = thesis. State your own opinion on the topic along with 2-3 reasons for support.

Water pollution impacts how humans and other living organisms live their life. Most common way humans are effected by water pollution is through diseases while drinking the water. Scientists have found over “five hundred different types of diseases” that can affect humans. (Book). These diseases get into the water streams by human and animal wastes. The diseases in the water can often lead to death for humans. Recent research has shown that that each year

Water: Pollution affects our water through rain clouds, because if the pollution gets into the rain clouds, it makes the water in the cloud more acidic, and if it becomes acidic enough it turns to acid rain, which is obviously not good to drink, wash, or use.

According Oraclethinkquest, "Water pollution has the potential to have a harmful effect on all living things including plants and animal species. Chemicals, radioactive waste, industrial waste in the water can affect species and their development. There is no

Three main ways our public drinking waters can become contaminated are by agricultural runoff, which have effects that go all the way from the effects of the remnants left behind from sprayed pesticides and unmanaged animal feces. Second, we have an oil and coal industry that just never stops. What comes from our oil industry ultimately ends up changing and altering the biology of the surrounding water with thermal pollution, and in some cases I have seen this reported as just as if not more damaging than bacterial or sedimentary pollution. The coal industry pollutes surrounding waters with sulfides from leaching. Illustrations are given below.

When we talk about how water is being polluted we just justify ourselves saying that there is a lot of water in this world and that a little bit of it getting damaged doesn’t matter at all. To understand the consequences of water pollution we first have to know what water pollution is and how it happens. Water pollution is the contamination of water bodies like lakes, rivers and oceans. This form of environmental degradation occurs “when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds” (“Wikipedia”). Chemical waste from factories is sometimes dumped into rivers and lakes. These chemical

Lead, a naturally occurring metal and can be used in almost everything. It can cause serious health issues if it is exposed for a long time, particularly in children as they are more susceptible to absorbing and retaining lead in their bodies. Each year, in the United States 310,000 of 1- to 5-year age group are found to have unsafe levels of lead in their blood, which can cause a wide range of symptoms. (1)

A reason that water pollution is a problem today is because many people don’t realize that they are hurting out water supplies when they really are. There are many pollutants that hurt our water supply such as farming. When farmers spray their fields with chemicals and apply fertilizers. Some of these chemicals reach the river, and animal urine and manure may be washed into the river. Another cause of water pollution is from accidents, such as tanker spills. Accidents with chemicals may cause river pollution as well. Mining can be another cause because the dusts and minerals get washed into the rivers. Seepage is another cause of water pollution. Because chemicals from waste dumps join the groundwater flow into the river. Urban Wastes is a major cause because the sewage comes from toilets, sinks, and industrial processes. This causes many human diseases such as diarrhea, dysentery, hepatitis, and cholera.

Inorganic chemicals is one of most important causes to water pollutants. These inorganic pollutants naturally found in environment but due to human develepment activities, these pollutant amount has been increasing rapidly and released into water bodies. The most common inorganic pollutants from water are ammonium, phosphorus, arsenic, cadmiun, zinc, lead etc. It is highly toxic to human and environment (Choi et al., 2011). The inorganic pollutant such as ammonia and phosphorus promote eutrophication, which excessive amounts of these inorganic pollutant releasing into the water can accelerate this phenomena in a few years (Donald M et al., 2002). The overgrowth of plants and subsequent death have been created green layer on the surface of water bodies. These layer can be blocked the penetration of light and oxidation process into the water bodies. Thus, depletion of dissolved oxygen can be occurred in the water and affected aquatic life. The death and decay of aquatic life contribute unpleasant smells and increasing the turbidity of water bodies (Conley et al., 2009). In additional, the heavy metal such as arsenic can causes skin, lung, bladder, and kidney cancer as well as pigmentation changes, skin thickening (hyperkeratosis) neurological disorders, muscular weakness, loss of appetite, and nausea (Mohan and Pittman, 2007). The long term exposure to cadmium causes various types of acute and chronic disorders like pulmonary odema, erythrocyte destruction, skeletal

Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities.
