Oceans are polluted by oil daily from oil spills, routine sea shipping, runoffs, and dumping oil straight into the ocean. An oil spill is the discharge of petroleum into habitats by vehicles, vessel or pipelines. It occurs extensively and it mostly takes place in water bodies. It happens due to human carelessness. Spilled oil can harm marine animals because its chemical components are poisonous.
Certain species have a huge impact to an ecosystem, but even the smallest fish could have the biggest impact. Overfishing occurs when more fish are caught than the population can replace through natural reproduction (overfishing). The results not only affect the balance of life in the oceans, but could also affect the coastal areas that depend on fish for their way of life. For centuries, our seas and oceans seem to be considered a limitless food supply. But that is not the case, increasing fishing efforts over the last fifty years as well as unjustifiable fishing practices are pushing many fish stocks to the point of extinction.
When fish consume the plastic, it will move up the food chain and affect other aquatic animals that consume fish. “Endangered wildlife like Hawaiian Monk Seals and Pacific Loggerhead Sea Turtles are among nearly 300 species that eat and get caught in plastic litter” (“Ocean Plastic Pollution”). If an animal gets caught in plastic, then it could suffocate them. “In 2008, two sperm whales were found stranded along the California coast with large amounts of fishing net scrapes, and other plastic debris in their stomachs” (“Ocean Plastic Pollution”). When an animal eats plastic, it causes their minds to believe that they are full but plastic does not give them the nutrients that they need and will cause them to starve.
Causes and consequences The principal reason the ocean is contaminating is because of humankind, such as factories, trash, petroleum, deforestation, and other reasons. Most of our trash is made of plastic, it takes 1000 years to degrade, this material has killed thousands of animals per year, because they get intoxicated or affixed. The glass is another material that can kill animals of the ocean, some fish may get stuck inside the bottle and die because of hunger, others may eat broken glass and bleed out because in damaged its organs. If you eat a banana at the beach or any kind of fruit, there's no problem, this is biodegradable, this cannot hurt the ocean or the marine species, also this degrades so fast that it's still not dangerous
Many marine mammals mistake these for food (Greer, Abigail). Plastic kills fish, birds, marine mammals, sea turtles, destroys habitats, and affects animal mating rituals, which can result in devastating results, such as wiping out an entire species (“How Ocean Pollution Impacts Marine Life-and All of
Sea turtles often eat plastic bags instead of jellies. This cost for turtle a life, as plastic causes a blockage within digestive system. But this is only the beginning. Spots made of plastic cover for Sunlight cannot penetrate through plastic garbage into the water, algae and plankton, which is the bottom of the food chain, may simply die out. The situation can quickly turn into a global crisis.
These information is telling us about the depth of the oceans dumping, and how people are throwing trash into the sea, and not throwing them properly away in their right place. The source is also giving other ways to help stop throwing trash into our oceans and spread the awareness between people. The author of this article is Rodman Griffin. I didn’t find any information about the author on that site. The purpose of this article is biased on not to dumping trash into the 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.
Thirdly, the ocean and its inhabitants are greatly affected by marine pollution. Marine pollution is the entrance of hazardous materials into the ocean. The ocean can be polluted a number of ways, including garbage, sewage, and noise. Garbage pollutes the ocean by disturbing marine life and tarnishing the marine environment, it can also damage ships. Sewage pollutes by adding dangerous chemicals to the ocean and depleting oxygen used by the animals.
Dispersants cause the oil to break up into smaller droplets, which become miscible in water. However, these dispersants may result in more ecological harm than good. The chemicals contain nonbiodegradable toxins that can kill fish and migrate great distances. Dispersants also are blamed for the massive oil plumes several hundreds of feet underwater, harmful to all aquatic life, especially fish larvae and filter feeders. Moreover, because of the large volume of oil that has been spilled, the amount of dispersant required and the amount of oil dispersed simply suppresses the problem, rather than solving
Ocean acidification is killing off the oyster population, which is also affecting the jobs in Washington. Initially, ocean acidification is when acidic gases are emitted into the air and absorbed into the ocean. According to the video Ocean Acidification by NOAA, ¼ of all the carbon dioxide release into the air is absorbed into the oceans. Some major contributors to carbon emissions are automobile gas and factory emissions. This is a problem in the Pacific Northwest because acid sinks to the bottom, but Pacific winds bring acidic water up from the bottom near the shore by the shellfish.
As humans expand they are producing more waste and need a place for it to go. In some countries, people just pump the waste into the water, as a result it is harming the manatees. The waste that humans are pumping into the ocean is causing toxic algae which the manatee eats and it makes the sick or could kill them. The waste from humans hurts the manatee also by
