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. This allows overfishing to be a problem. Not to mention, another environmental threat that this fascinating animal, the blue crab, faces is climate change. Corresponding with the text, “Climate change is another major threat to life in the oceans. Warming ocean waters, rising sea levels, and violent storms disrupt the lives of many species and affect fragile marine ecosystems,” (Digan 14).
Although recycling makes a difference, many container still end up in beaches and oceans. The drink containers cause death and injuries for many wildlife and marine creatures. Animals like whales and dolphins become victims of land litter, as 80% of majority of the plastics comes directly from land. Dr Jennifer Lavers, researched the impacts of plastics on marine life, claims that 85% of Australian marine birds are affected by plastics (Stop trashing Australia, 2012). Apart from animals getting tangled in debris, it is extremely harmful when there is run down fishing gear, as it results in ‘ghost fishing’.
Economies highly dependent on tourism, and fisheries may suffer the most. Big-ticket fishing and shellfish areas may be closed down, to reduce the risk of human consumption health effects. Not only will the fishery businesses suffer a huge financial loss if consumers are stopped from or unwilling to eat the fish, many may also be out of a job. Ironically though, because people are needed to tackle the sometimes massive cleanup, it is possible for an economy to see an increase in jobs following a spill. One study from 2015 about the long-term effects of the oil spill in the Gulf of Mexico from the Canadian Journal of Fisheries and Aquatic Sciences, projects a loss of more than 22,000 jobs by 2020, as a result of the impacts to businesses that rely on heathy fisheries.
Hence, overfishing threatens coastal nations down to the local level, devastating communities whose dominant sources of labor and revenue hinges on healthy, plentiful stocks of fish. Also, marine life imbalance may affect the targeted fishing of top predators such as billfish, sharks and tuna that eventually disturbs marine communities. In fact, it is causing increased abundance of smaller marine animals at the bottom of the food chain. This in turn has impacts on the rest of the marine ecosystem, such as the increased growth of algae and threats to coral reef health. Overfishing is also closely tied to by catch, another serious marine threat that causes the needless loss of billions of fish, along with marine turtles and
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.
Be aware of what you are putting into the ocean and what effect it is going to have on marine life. In conclusion, the amount of oxybenzone going into the ocean is devastating. It bleaches the corals, which then harms marine life, upsets the ecosystem, and effects the economy. Even though we may not realize or appreciate them, coral reefs provide so much to our world. Without them, people would have a difficult time going about their day to day lives and would struggle to get
As said by Friedrich Nietzsche, Thus Spoke Zarathustra “One must be a sea, to receive a polluted stream without becoming impure”. Air wildlife are also greatly affected by plastic pollution. Seabirds area a common example. Seabirds often mistake trash floating on the ocean’s surface as prey. Or often their food sources had already ingested plastic debris, thus transferring the plastic from prey to
Killing the dolphins in the coves turns the water completely red from all the blood. When this happens it is releasing massive amounts of mercury back into the oceans which eventually contaminated other sea creatures (Glionna). Maybe the slaughters would be okay if the country followed all the rules and regulations; however, they are not abiding by the species of dolphins they are allowed to kill. They are only supposed to be allowed to kill Bottlenose Dolphins but they are also killing several other species in the process (McNeil). The main species being killed are the Bottlenose Dolphins, Spotted Dolphins, Risso’s Dolphins, False Killer Whales, and Short-Finned Pilot Whales.
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?”
Nassau, the capital of the Bahamas struggles a lot with plastic pollution because its main income and food source is fishing. Plastic pollution hinders the amount of fish they gather and therefore slows down the rate of their income. Nassau is already a LIC and therefore plastic pollution causes famine there. They have already started to think about banning plastic bags. And if the plastic pollution rises then there will be losses of $8.5 million in tourist income annually for the country because of the pollution on the beach this happens in other countries as well.
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.
If the Salton Sea starts to dry up severely both wildlife and humans will be affected. The more it dries up, the more toxins are sent into the air. Residents that live near the Sea and even people that live very far away will inhale these toxins that can potentially cause cancer. Deaths have already occurred as a result of this and many more are bound to happen. The Salton Sea serves as an important stop for migrant birds.
Louisiana 's marshes are constantly changing, and it 's costing a lot of money to save it. The cost is $14 billion to stop coastal erosion, which is at a rate of losing 2.5 acres of land per hour. New Yorkers should help pay for the cost too, as they are also being affected levees, man-made and natural causes, economically, environmentally, and socially. The main problem with the marshes is coastal erosion, which is affected greatly by levees. Levees direct river water straight into the Gulf of Mexico, where it no longer deposits sediment along the coast (p. 36).
Red Tide: How it affects Marine Life Red tide in Florida is a reoccurring problem that threatens marine life every year. Red tide in Florida waterways has a negative impact on marine life because it produces toxins that are harmful to marine species. It lessens the amount of oxygen in the water which ultimately leads to the migration and death of many different marine animals. Millions of dollars are poured into red tide research and prevention every year to help predict when and where a red tide is going to form. All the while, millions of dollars are being lost due to a drop in tourism and bans on fishing as red tide wreaks havoc on businesses and marine life.
Researchers found a thousand- five hundred particles per square mile. The garbage did not only just clog the water but the chemicals in the plastic bottles that can affect the fish the people farm in for a living that could change their life habits and animals that could go in extinct. Plastics have been entering the ocean every year and has become worse since now. By this problem we can start recycling water bottles that we see so we can start making it to use again instead of littering our ocean with plastic that has become a disaster. Not only the ocean is filled up with garbage but it also can cause infections in the water.
