Oceans are being polluted by substances such as farm fertilizers, chemicals produced in factories, and harmful sewage from towns and cities (Claybourne 38). Trash and debris, especially plastics, are deposited into the oceans by humans. These objects can be mistaken as food by many species, which eventually leads to death. When species consume what looks like to be food, but in reality is hazardous waste, the animal contains that chemical inside of them. When a larger animal consumes the hazardous animal, it affects the entire food chain (“What Is Ocean”).
Ocean Pollution DBQ Did you know that every year, eight million metric tons of plastic is dumped or somehow ends up in the ocean (Doc. 1)? The following sentences will talk about what people are doing to pollute the oceans and how they are making the pollution better. Humans are the biggest threat to animals in the ocean because they litter so much (OI). Sometimes, people litter without even knowing they're littering.
Over 780 million people are without access to clean drinking water, and around 2.5 billion people do not have access to an adequate sanitation facility (Bradford). There are two primary ways in which water pollution is caused. The first way consists of objects such as trash from a landfill or parts of a boat which have fallen into the water. The other cause is due to fertilizers and other chemicals being spilled into the water ("Pollution"). Once enough pollutants fill the water, it becomes likely for it to become contaminated with dangerous pathogens, which survive on the pollutants and can be dangerous to the wildlife.
Negative Effects of Ocean Pollution “Each day, oil used to lubricate engines and to power the vessel leaks into the ocean” (Wroble 44). When the residue enters the ocean, it begins to affect the environment and animals. This is just one of the many problems from ocean pollution. “According to Worldwatch research associate Peter Weber, 80 to 90 percent of all of the materials dumped at sea are dredgings...dredgings are rich in toxic chemicals...from nonpoint sources” (Wroble 49). One particular chemical that affects the oceans are Polychlorinated Biphenyls, or PCBs.
As two third of the earth is covered in water, if one placed gets polluted there is a way that the whole water in the planet can be polluted. 70% of earth is covered in water. Water is a very important resources for every living lives. Water pollution cause danger in the aquatic life and to humans and it leads to extinction of aquatic life that affects the food chain. If there is effect on one place of food chain, the whole chain will break and cause danger to people and animals.
Alex Grommesh Ms. Heise/Ms. Keel English 2 16 March 2018 The Negative Effects of Water Pollution The majority of all marine ships dispose of their waste by throwing it into the sea (Wroble 41). If they are caught doing this they can be charged for littering and be given anywhere between a three hundred to a two thousand dollar fine (this fine can be more or less depending on where it occurred). Furthermore, if what is being dumped is considered hazardous to the environment a jail sentence can be given to the perpetrator (“How Can Water…”). As you can see water pollution is a punishable crime, but do you know why?
Water is a necessity for all life on Earth, yet it is one of the most threatened vital resources in the world. “Water pollution is any contamination of water with chemicals or other foreign substances” (Water Pollution). From automobile fluids that seep into sewage systems to household products that are usually poured down sinks, all these items can contribute to the destruction of the environment. However, these items have a common denominator: humans. Not enough people are aware of the dangerous effects that water pollution has towards the environment and what causes it.
Oceans are vast water bodies, and large quantities of wastes have been dumped into them under the assumption that its not a serious problem. But recently many reports show that ocean waste is accumulating at remote sea shores causing problems to the local people there. This has brought into light that dumping waste in oceans is not sustainable. Earlier, the wetlands used to help filter out a major share of the pollutants from the runoff before it joins the surface water. As cities expanded, most of the wetlands got converted for construction
Water is regarded as polluted if certain substances or conditions are present to such a point that water cannot be used for specific purposes. Water is defined as the presence of excessive amounts of pollutants in water in such a way that water is no longer suitable for drinking, bathing, cooking and any other uses. Pollution is said to be the introduction of contamination into the environment. Pollution is created by industrial waste, commercial waste, agricultural activities and human activities such as transportation (Owa, 2013). Sources of water pollution According to (Owa, 2013), water pollution arises from various activities such as sewage, leakages, high population density, oil spilled, industrial waste dumped into waters, flooding
Sherri agrees to state, “Birds, fish, and other aquatic (water-dwelling) species swallow these pieces, possibly mistaking them for food. Once consumed, the plastic pieces collected in an animal’s gastrointestinal tract, interfering with its ability to eat and drink and thus leading to starvation, dehydration, and possibly death.” This means water contaminated with trash could lead to more sea creatures dying from it. This contamination, if it got extremely bad, could wipe out some marine species which could mess up the food chain which could lead to the death of other marine life. Sherri also states,”the decay process requires oxygen, the additional decay uses up more of the oxygen in the water. Less oxygen remains available for living things.” This means decay of some marine life bodies uses oxygen which causes there to be less air in the water.
