People used to use only tanned beluga skin as leather because it was only leather that they can use. b. In the 18th and 19th centuries, Europeans and Americans hunted beluga whales for several reasons: using the meat and blubber, beluga whales’ oil to lubricate watches, machinery and illuminate lighthouses. According to the data, from 1868 to 1911, Scottish and American whalers caught more than 20,000 beluga whales in Lancaster Sound and Davis Strait. c. In the 1930s, beluga whales had been killed along the St. Lawrence River by fishermen because they thought whales destroy the fishing industry.
There are five main things that affect the ocean and harm it, Whaling, overfishing, factory fishing, global warming, and pollution. Every year the Japanese government kills mink whales. They kill at least eight hundred fifty of these whales. Factory fishing is also a major harm to the ocean. Factories create equipment that destroys species in the ocean.
Conclusion Introduction Everyday thousands of marine animals were being cruelly killed in many parts of the world. Most of them were for money. It grew worse after egg collection became legal in 1987.Many species of sea animals are in the verge of extinction. It includes whales, turtles and many kinds of fishes. Latest technological advances have increased the threat to the marine animal, especially for turtles.
In the beginning of the 20th century whalers began to exploit the herds of southern whales. With an industrialized approach to whaling in place the numbers of species began to rapidly deplete - some whale species had been reduced by more than 95%- , until some species such as Right, Blue and Humpback had been almost wiped out. In 1986 the International Whaling Commission (IWC) – which has over 70 member countries around the world, and has the purpose to provide for the proper conservation of whale stocks and thus make possible the orderly development of the whaling industry - banned all commercial whaling through a moratorium, but since then, three nations - Iceland, Norway, and Japan - have brutally slaughtered over 25,000 whales under the guise of ‘scientific research’ and for commercial purposes (Sea Shepherd). The Japanese invented the concept of 'scientific' whaling in 1987 as a way round the moratorium on commercial whaling instituted by the International
Comparing slavery to the whales is one of the ways Cowperthwaite portrays SeaWorld as being evil. SeaWorld makes many false claims to convince the general public that they are in the right. Claims such as lifespan (25-30 years more with veterinary care), Dorsal Collapse (25 percent), the whales are a family, and aggression is accidental or the trainers fault. In actuality lifespan reaches 80-90 in the wild, Dorsal
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.
It would interfere with millions of migratory birds that feed on its tundra plains. It would kill plants and animals that are native to the Beaufort Sea area and the environment would take two decades to recover. If there were a major oil spill, it would decades for the ecosystem to recover, since so many organisms would be contaminated and eventually die. Remember the 1989 catastrophe when the Exxon Valdez spilled 35 million gallons into Prince William Sound? The
Drowning in Plastic It’s hard to imagine life without plastic. It’s everywhere: covering our food, holding our purchases, protecting our loved ones, saving patients in hospitals and floating along our waterways and oceans. The thought of living in a world surrounded by toxic chemicals and pollution is a thought which many would rather not think about. Plastics have revolutionised the world in which we live, but with dire consequences. The production of these toxic-filled substances continues to lead the human race on a path of natural destruction; with thousands of animal sea-life dying annually from plastic consumption.
What has happened to destroy so many reefs? Human population has become very large, and earth is warming. There are two different ways in which humans have contributed to the degradation of the Earth's coral reefs, indirectly and directly. Indirectly, we have destroyed their environment. The large population centres near coasts has led to silting of reefs, pollution by nutrients that lead to algal growth that smothers the coral, and overfishing that has led to increase in number of predators that eat corals.
Killer Whales in Captivity: Entertainment or Torture? The death of the SeaWorld Orlando’s trainer Dawn Brancheau, in 2010, by one of their performing orcas (named Tilikum) and the subsequent release, in 2013, of the documentary Blackfish, have raised a major controversy not only among animal advocates such as PETA (People of Ethical Treatment of Animals) but also the regular marine park attendees. If the incidents presented in marine parks around the world, over the course of several the years, were not been hidden or ignored, this horrifying accident could have been prevented. The fact that some incidents were kept a secret from the public and new trainers, worsen the situation. After so many years and incidents, the captivity of killer whales or orcas (Orcinus orca) merely for entertainment purposes should be prohibited.
