A remote island that has remained uninfluenced by humans is now on the verge of losing its wolf population due to genetic deformities. The island is called Isle Royale and its once abundant wolf inhabitants have now dwindled to three remaining wolves. This leaves many scientists and researchers with the question of what actions to take in order to save the wolves from extinction. After researching and gathering information, it is clear that the best way to save these wolves is for humans to immediately introduce more wolves to the island in order for the island to flourish, genetic variation to expand, and the number of wolf offspring to rise.

I agree that saving underwater sea animals is important. Sea otters have been dying at a higher than normal rate . Their health can tell us a lot about the whole
Overhunting has had an effect on several different species, the one I will be telling you about is the Harp seal. The harp seal is located in the “west ice” of eastern Greenland, in the “east ice” of eastern Russia, and off the cost of east Canada and are currently being over hunted by humans. Harp seals, and others like the Namibian cape seal, are currently slaughtered more than any other marine mammal in the world. Harp seals are usually 3 weeks to 3 months old when they are clubbed (being hit with a club, like a golf club, until you dead), bludgeoned (being hit in the head with a large, heavy object really hard), or shot to death by a few hundred or a few thousand fishermen, depending on how well they can get to the seal, each year.

The sea otter is a marine mammal that lives in the northern and eastern coasts of the North Pacific Ocean. They are the heaviest members of the weasel family but are some of the smallest marine mammals. The sea otter has no blubber and the main way to keep warm is its thick coat of fur which is not like most other marine mammals. Did you know the sea otter has 150,000 strands of hair per square centimetre, because of this the Sea otters have the thickest fur of any mammal. In the Maritime Fur Trade, which would eventually kill approximately one million sea otters, began in the 18th century when hunters and traders began to arrive from all over the world for otter pelts, which were one of the world 's most valuable types of fur. The
Imagine you are stuck in a jail cell, blindfolded. You are forced to do ever anyone says, and you do tricks for other amusement. That’s how a whale in captivity feels all the time. Whales shouldn’t be held captive because whales are taken from their families, whales are forced to do shows, and most importantly whales have to live in to small tanks which can be harmful to the whale.
The Hawaiian monk seal, or Monachus schauinslandi, was one of the original species to be placed under the Endangered Species Act that was enacted in 1973. As of 2010, the population of the monk seal is approximately 1,100, with an annual decrease of approximately 4.5%. The Hawaiian monk seal is primarily found on the Northwestern Hawaiian Islands that are made up of coral reef atolls, seamounts, banks, and shoals. This is due to the fact that the monk seals primarily forage on the barrier reefs of the atolls, on submerged reefs, and on banks further from the atolls (Curtice et al, 2011). The monk seals primarily like to look for food on the surface of the ocean floor and will search for food in depths up to 500 meters. (National Marine Fisheries
Otters have a unique history in Alaska. They bounced back from the fur trade, that began in the 1700s, that almost wiped them out. Today otters face other threats. Apart from disease epidemics, otters continue to be threatened by overharvest, interactions with fisheries (e.g. gear entanglements), oil spills and being prey to killer
Subpoint: Wildlife— There are two primary types of impacts that occur with a spill of crude oil
In both of these articles by Christine Dell’Amore and Matt Miller, they discuss how these top predators impact the island, why they are they important, and should humans interfere? On the island of Isle Royale, there is a variety of animals that mostly just consume vegetation; therefore, they need wolves to balance out the food chain. But, the island is only accessible during the winter when stable ice bridges are created. Unfortunately, the ice bridges have not been forming due to warmer winters. Leaving a small count of wolves on the island with no new genes to mix in. Without the new genes, the wolves resort to inbreeding which causes bad immune systems, weak bone structure, and other deformities. Due to these deformities and lack of ice
The seal hunt should be banned. They are being hunted for their fur. Canada allows 470,000 seals to be hunted every year, and that is endangering the seals population. Hunters specifically look for baby seals to hunt. They do this because their fur is very soft, and they have a lot of value in them. The seals that get killed for their fur are all 2-3 weeks old. These animals are getting killed very often, and they get killed in a very painful way. Hunters don’t shoot the animal. Shooting the animal is much more effective and it will put it out of its misery faster, but hunters use clubs to beat them to death. Seals are being hunted, and it should be banned in Canada.
Third, the author asserts that scientist believed that the pollution hypothesis could also the uneven pattern of otters decline. However, the professor opposes this pint by explaining that the uneven pattern is better explained by orcas predation theory. she added that it depends on whether the location is accessible by orcas or not, so because orcas are large, they can 't access the shallow region where sea otters have not
The professor argues predation is the more likely cause than pollution because of the absence of dead sea otters washing up on shores. However, the reading passage attributes the decline of the sea otters population based on evidence of increased ocean contaminates leading to greater vulnerability to infections.
“In the animal kingdom, the rule is, eat or be eaten,..” Stated by Thomas Szasz. The animals live in a way where if they are not on the top of the food chain, they live in fear and worry that they may be eaten. In the article Dread is vanishing from the animal world. Here’s why that's a bad thing, by Sarah Kaplan, she explains how we as humans are leading top predators to go extinct or come close to. Sarah states, “the largest predators are dying out and no longer a threat smaller animals feel more secure and nature is thrown off balance,” The small animals live in fear, so when they go out for food, they don’t look long because they are always on the lookout for predators. When the smaller animals realize there is no danger, they eat more,
Otter populations begin to dwindle every year by the hundreds due to lack of them already. By this time only around 50 otters escaped the slaughtering by moving south to the remote Sur coast. Which they stayed there with populations rising into the thousands and brought down by a poor environment and overhunting to the hundreds once again. But the Monterey Bay Aquarium from 1911 to 2014 is still working on healing the otter population back to the way it was. Southern sea otters were put on the national fur seal treaty for protection and were no longer hunted to the brink of extinction. Their aquarium helps many different species rehabilitate in their aquariums until they are ready to go back into the ocean and fill their niche in the environment. By nursing otters back to health and having them released back into the wild has helped the population stay in the thousands, “they 've slowly expanded their range and grown in number to nearly 3,000. As of 2014.” (Monterey Bay Aquarium: Sea Otter Article). The aquarium while also helping wildlife gain a healthy state on earth, they also of course, run an aquarium for people to view the animals in their
