Have you ever been swimming in an ocean, and you notice a plastic bag or bottle floating in the water? There are many ways people can pollute the oceans. For starters, oil tankers spill oil into the water (Doc 2.). Boats sink (Doc 2), and eventually the boats break up into pieces and spread across the ocean floor (OI). Next, people dump sewage and garbage from boats and on beaches (Doc 2).…
These effects are brought about as a result of ingesting plastics, liberation of plastics toxins, from getting entangled in plastic debris and through the food chain. Actions to reduce plastics in our oceans are very necessary. As a result of eating plastics, these beautiful marine creatures sadly harm or expose themselves to death. Their digestive system may be blocked, or destroyed at any level. The induced false sensation of satiety expose them to hunger and death.…
Thus, it is not caused primarily by those activities that take place in the ocean, but of those which are not. According to (Carl J. Sindermann in his book Ocean pollution: effects on living resources and humans) he mentions that as coastal areas continue to expand in terms of people and industry, so does dumping in the ocean. Hence, this waste to the sea comes in many forms such as trash, sewage disposal, toxic chemicals and…
Environmental pressures mainly take the form of marine debris and terrestrial pollution. Marine debris that is not adequately disposed of can harm organisms that may become entangled or caught in debris, specifically threatening the lives of sea turtles and seabirds. Additionally small forms of plastic that may come form various sources also pose a threat to shearwaters and seabirds that may consume these pieces of debris (Fry et al. 1987. While the risk of entanglement remains low due to fishing prohibition, terrestrial pollution that washes ashore (i.e. lead based paint that are ruminants of old vessels/buildings) could lead to lethal consequences if ingested by organisms.…
Combined that with marine pollution which depletes oxygen for marine creatures, it can make survival difficult for sea life. Hazards within the oceans aren’t the only concern that worries the artist. With much of all land creatures as well as plants living in forests, deforestation can destroy the land creatures and plants home. Moreover, deforestation affects land creatures and plants survival as a result. We can see how deforestation, pollution, and overfishing are endangering both, sea life as well as organisms that live on…
The main chemicals causing poisoning of wildlife are herbicides and pesticides from garden and park run off. Sewage out fall can cause excessively high nutrient levels and pathogens that can be harmful to all marine life. An excess of nutrients may cause, toxic algal blooms or extreme plant growth that will affect the amount of dissolved oxygen when they die. With the increase of the urban areas near the coast the more likely it is that rubbish will be dumped or blown into the estuaries which may cause organisms to suffocate. Many construction sites will cause sediment build up in the habitat, the sediment can decrease water quality, reduce light penetration in the water and restrict bottom dwelling plants and…
Ocean Acidification-Effect on Squid Ocean acidification is a direct result of rising atmospheric carbon dioxide CO2 concentration due different type of human activities, such as burning fossil fuels and deforestation (Halpern). The world’s ocean surfaces have gradually become more acidic due to absorption of excess anthropological carbon emissions throughout history. Since the Industrial Revolution during 19th century, the carbon dioxide level has been dramatically increasing. In addition, the CO2 concentration level has reached a constant of 280 ppm during Pre-Industrial and will reach 700ppm by the year of 2060 under the projections (Cooley). Figure 1 shows that as the carbon dioxide levels increase in ocean, the pH level decrease.…
The litter is killing many species of marine life and even birds. The animals see them and assume it is food and go to eat it, often getting caught it their throats or not being able to digest it will most likely kill them. Examiners have found various pieces of trash inside the stomach of many sea creatures and birds. According to reports, more than one million birds are dying as a result from ocean pollution. Another issue with the ocean is the pollution going into the water.…
These pollutants have an adverse effect on fish populations in the bay further…
Greenfield, David W. "Toothfish." World Book Student, World Book, 2017, www.worldbookonline.com/student/article?id=ar751020. Accessed 29 Nov. 2017. David Greenfield wrote about what type of fish are being overfished and if they are just the ones that can be eaten. The main type of fish being overfished are the fish that people need to eat for food.…
Laws are being made to try to prevent pollution from land, sea, and air to protect endangered species, and to try to build marine protected areas. Pollution has been harming organisms all over the world and will continue to harm these species without the effort to help stop polluting the oceans. Oceans absorb 80% of greenhouse gases and 50% of the carbon dioxide released into the atmosphere. Over the past 50 years, as carbon dioxide emissions have increased, the ocean's temperature has steadily risen. Natural disasters are also affecting the oceans.…
The destruction of the ocean ecosystem means that the biodiversity of all global ocean populations are harmed. With the fish population decreased, future generations are unable to use the fish as a resource. With the ecosystem damaged, it is difficult for the fish to repopulate, and the ocean as a food resource is scarred. There are other resources that have their sustainability damaged because of improper…
The way we neglect our ocean with heavy amounts of pollution can potentially affect our lives in a negative manner. Driving cars and the use of plastic is essential to our daily lives, but we use them without the concern for how they are affecting the habitats on Earth. Some people think that the chance that they are doing harm to the ocean is less important to them than cost or inconvenience of fixing a pollution problem. Through sources from researchers and scientists, they have found evidence of pollution caused by the two essential commodities in our lives, plastic and burning fossil fuels. Environmentalists have found solutions to reduce the plastic waste in our ocean as well as attempting to reduce carbon dioxide emissions in the atmosphere…
Artificial fertilizers pour through our streams into the ocean every day. Storm drains and their underground channels collect the toxic waste from our sidewalks, streets and highways and take that toxic cocktail to mix in the ocean. Even in more “developed” countries like the United States and even in areas such as southern California there are incidents where sewage treatment plants malfunction and human waste is discharged into the ocean. Manufacturing processes and the waste from lights, computers and thousands of other modern inventions, result in the contamination of our oceans. Ever increasing levels of mercury in the oceans’ waters is well known, but there are others as well.…
Animals such as sharks and whales rely on water to survive. If the water that these sea animals need to survive is polluted then they will not thrive and will ultimately die. When water is polluted with various types of garbage and chemicals, the fish and other seas either get caught in some of the trash or digest some of it. Sea animals are notorious for getting caught in the plastic that is used to hold cans of pop, thus trapping them limiting them from being able to eat anything. That can lead to plenty of deaths to fish and plenty other animals that live in seas.…
