The droughts and increased heat has had negative impacts on local aquatic invertebrates. Aquatic invertebrates are adapted to survive in a particular range of temperature and habitat. But global warming makes it harder to survive. This could lead to the extinction of several species of aquatic invertebrates which in turn would lead to serious consequences of the ecosystem. Many of the aquatic invertebrates are responsible for keeping the ecosystem clean by feeding on litters.
These scientists play a very important role in developing new ways to protect the seal population. In relation to this article Duke University faculty and the International Fund for Animal Welfare were major stake holders in publishing the study. The issue of the decline in harp seal population is global, economic and biological. The warming of the oceans’ waters is a problem that humans and wildlife are facing all over the world. It is also a problem that does not have many possible solutions, causing it to be the most detrimental to harp seals.
These emissions can become acid rain and if it can damage a tree, it can and does damage coral. According to the Coral Reef Alliance; the world’s oceans have had “approximately 525 billion tons of carbon dioxide” dumped by human activity within their waters. [ (Coral Reef Alliance, 2012) ]. The site also goes on to state that the destruction of Mangroves,(which have been harvested for lumber) and the loss filtering saltwater swamps due to farming have caused quite a bit of stress on coral reefs. Then there are the odd ways we humans go about “enjoying the ocean”.
Beach closures have also been more frequent being something many families, and residents have once enjoyed. These toxic chemicals have been found in fish and wildlife, which have been deposited into the lake by manufacturing sites and other industrial companies. (Glutting, 2003)Runoff pollution, pollution that comes from a single location has also added to the lake’s devastation. Storm water, irrigation runoffs, sediments, fertilizers, and fecal matter deposits, are some of the discharges contributed by sewage treatment plants. These runoffs have contributed to the beach closures, and the unsustainable condition of biological life in the lake.
We are worried they will be weak, and the calves won't be born healthy in the spring. "Whether it's blizzards or hurricanes or floods and heat waves, extreme weather events due to climate change are headline news in Southern Canada. In Nunavut, however, the effects of global warming are destroying the Inuit way of life. And Watt-Cloutier, in her role as chair of the international Inuit Circumpolar Conference (ICC), is confronting the climate-change beast. She has placed her name as principal plaintiff on a petition to the Inter-American Commission on Human Rights and is requesting relief from human rights violations due to the world's most pressing environmental problem.
Dr Carl Meyer from Hawaii Institute of Marine Biology stated that mass levels of shark culling “runs the risk of ecosystem-level cascade effects where a general lack of sharks results in boom or bust in populations of species further down the food chain”. Furthermore when nets are used to trap sharks, often animals such as dolphins, turtles, whales and dugongs become trapped in them. Turtles are one of the most endangered species as a whole and are just innocent bystanders in this war between humans and sharks. We need to be careful of not affecting other animals in this quest to reduce shark numbers in the name of nothing. Sharks can already be caught legally by commercial and recreational fishers so any cull would be largely
Contaminating these waters will not only harm the wildlife, but it will kill a source of food that is so dominant in Newfoundland, and also will harm hundreds of people’s jobs. Oil spills cause a lot of problems in our ocean and to our marine life. Everywhere you look people are trying to create a more sustainable ocean, and this is hard to do when there is so much pollution and threats to our environment all around us. We, as youth need to step up and try to make a change and help to make our province a better place. We can help thousands of animals survive by taking action against oil drilling in our
The Arctic as most know is known for its fisherman and whalers, whom in the past overfished and whaling for the uses of oil, but cause a major downfall in the number of Arctic marine life. AS mentioned before with the climate change there will a larger number of fishing and whaling vessels due to the decrease of sea ice and the opening of Arctic waters that have never been accessible. Looking at the Arctic portal I found a list of restrictions that would be major to the fishing industry; 1. Restrictions on catch and effort, for instance by setting the total allowable catch (TAC) and allocating the TAC by means of national quotas. 2.
The resulting anxiety and tension cause fights between orcas. In the wild, orcas have strong social bonds that may last for life, their social rules prohibit serious violence against each other, and when fights do occur, they can find space to flee. In captivity, there's nowhere for them to go, which leads to injuries and death.” (SeaWorld of Hurt) Besides fighting with fellow killer whales, Orcas are biting the bars, concrete and tanks to escape due to stress and anxiety. The diet of a whale in captivity is unlike the diet of a whale in the wild. PETA’s campaign SeaWorld of Hurt shares, “In captivity, orcas are unable to hunt and obtain water from their prey, so SeaWorld gives them gelatin, a substance that is not natural for them, in an attempt to keep them hydrated.
Oil spills in this area would be extremely damaging because toxins from the oil remain in cold water for a longer period of time. The oil would also concentrate in the locations that provide breathing holes and congregations spots for these mammals. The toxins from an oil spill would stay in these marine mammals and have harmful effects on the related food chain when they are preyed and scavenged upon. The noise and disruption that would result from drilling would disrupt the navigation patterns and social interactions of these mammals. Out of all the marine mammals that would be affected, the bowhead whale would feel the worst affects of drilling.
