Luther King says in "9 Interesting Facts and Statistics about Littering", 1.9 billion tons of litter end up in the ocean. The ocean is another ecosystem made up of many diverse animals and plants. In “ 5 Ways Pollution Is Killing Animals”, Abigail Geer tells us that there are many things that can pollute the water ranging from noise, chemical and acid runoff, waste water and oils. All of these types of pollutions are affecting the marine life drastically. Abigail tells us that noise pollution is hurting animals that use sonar to get around are becoming closer to extinction.
This shows that an environmental threat that blue crabs face is pollution because if about 1 million animals are dying each year because of pollution, we have a serious problem. Furthermore, another ecological hazard that this incredible animal faces is fishing and it’s equipment. According to the text, “Modern fishing methods have created some serious problems for the ocean. The populations of almost all fish species that we eat have shrunken,”(Dignan 14). This proves that another environmental threat that blue crabs faces are fishing because they may not be a type of fish, but, like most crabs, they are fished, caught and sold.
Examples of negative local practices are the usage of poison/explosives and overfishing. Overfishing as the name suggests, is fishing a certain fish to an excess amount, decimating the population. This could put multiple organisms’ populations at risk and populations may possibly go extinct. Another practice that negatively impacts the ocean is the usage of poison and explosives. Obviously, the poison that is used in fishing (mainly cyanide) is harmful for the ocean because it may poison other fish over the years.
Believe it or not, it comes from us littering on the ground. Sun, wind, and water breaks plastics down into microplastic, and moves into the ocean to harm our sea life. Now, there is about 60 times as much plastic as there is plankton. Most animals mistake plastic for plankton. An animal's digestive system can't pass plastic, so it stays in the stomach until they finally approach death.
Marine mammals such as seals are being found entangled in plastic fishnets and several drown. It is tragic that the oceans have large amounts of plastic contamination which is causing problems with marine life and beach birds. It is discovered that these animals are mistaking small plastic debris for food, Susan Casey in her article, “Our Oceans Are Turning Into Plastic…Are You?”
It is also ruining the amazing marine biodiversity that South Africa has. Pollution not only comes from industrial sector such as oil companies, but also from littering and sewage. Plastic pollution is one of the types of pollution that effect the marine environment. It is impossible to give an accurate estimation of the amount of plastic that is being polluted into the ocean. However, in 1975 the global fishing fleet alone dumped approximately 135 400 tons of plastic fishing gear and 23 600 tons of synthetic packaging materials
There are millions of dolphins out in the oceans and they are declining fast because people couldn’t take another 12 steps to get to the trash cans that are all over the place in cities. Teens are the ones who mostly litter. Kamilo, an island in Hawaii is surrounded by thousands pieces of trash. They now call that place the Great Pacific Garbage Patch. It used to be a beautiful island but is now ruined by trash.
This can result in lung, kidney, and liver damage, as well as death from toxins. Oil spills also have indirect effects on these mammals, such as habitat loss and a diminishing food supply. Lastly, the oil slicks can make animals blind from continuous exposure. Because oil spills cause so much damage, many marine mammals die because of it. Whales, including dolphins,
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,
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.
