Why Is Sea Ice So Dangerous To Walrus?

Im doing glacier melting because it is important and we need that fresh water to survive.Also i think we should do whatever we can to stop the glaciers from melting.And it also will take the crops longer to grow. It would effect our food supply. And it could kill most wild life.

The melting sea ice is also affecting the polar bear's main prey, seals, forcing the bears to turn to alternate, less nutritious food sources. Once sea ice forms in the winter, seals use the ice to create dens to give birth to their pups. In these months, polar bears use sea ice as their hunting grounds to find seal dens. Now that Seasonal Ice is forming later and melting earlier (IPCC, 2013), seals have less time to build dens and give birth. Consequently, polar bears have less time to hunt their preferred prey of seal pups. They must spend more time on land hunting other animals of less nutritional value. Organizations like Sea World Parks have reported male polar bears occasionally eating newly-born polar bear cubs because they cannot find other food to eat. Lack of nutritional food leads to a reduced body size. Polar bears are becoming thinner and weaker from not eating enough (Rode, Amstrup, & Regehr 2010). They have to swim longer distances to find ice to hunt upon, causing many cubs to die because they are not yet strong enough. In the Hudson Bay, the average polar bear weight has decreased by 15% and the population has decreased by 20% (National Wildlife Federation). In the summer when there is no ice, polar bears in the Hudson Bay go onto land to fast until the ice reforms. Now that ice is

It also means that big chunks of ice will break off and create walls on top of the ocean waters. With the ice melting, the NarDewhal habitat has to change, but I don’t believe that they can adjust to such critical circumstances because their living environments are all about deep waters and ice. Although ice is not primarily what Narwhals live under, they need to coldness to live in the area. There was an incident in Canada that caused the Narwhal population to decrease substantially. Jaymi Heimbuch (2008) says that, “In a heartbreaking move, the Canadian government decided it would rather allow 500 Narwhals to be shot one by one at an air hole in the ice, rather than bring in icebreakers to help free the whales.” They could have also killed the Narwhals to receive money from the ivory and other parts of the Narwhal.

The biggest threat to the tundra is from oil and gas development that results in global warming. As the planet warms the permafrost melts and tundra ecosystems will collapse. Another, threat comes from airborne pollutants, which have brought measurable levels of pollutants such as DDT and PCB's to even remote areas because it is a great technical challenge to effect efficient sewage treatment in a cold environment. Lastly, the overpopulation of Canadian geese pose a threat to the tundra because the balance of the biome will be offset.

Summary of Case: It is illegal to kill Walrus unless you are a native and use all resources available from the animal. Natives

Although difficult to imagine, Ohio has at vari- ous times in the recent geologic past (within the last 1.6 million years) had three-quarters of its surface covered by vast sheets of ice perhaps as much as 1 mile thick. This period of geologic history is referred to as the Pleistocene Epoch or, more commonly, the Ice Age, although there is abundant evidence that Earth has experienced numerous other “ice ages” throughout its 4.6 billion years of existence.

Warmer winters leave seals without protective ice dens. This exposure to the elements increases infant mortality and leaves adults unprotected from fisherman. Fishermen use nets to trap the seals, which also end up littering the oceans. An average of 60,000 seals were killed each year between 1984 and 1994. Most of the pelts are first purchased by processors in Newfoundland. The seals are also facing pollution, which causes habitat loss. Predators of seals are the Orca, Killer Whale, Great White Shark, and Polar Bears. Global warming is another concern for seals. As the polar ice caps melts, the seals find more predators in their natural habitat. Which means they are at risk of being eaten as well as having to share their food and other supplies. Seals have to eat more to gain blubber and keep themselves warm. Seals that live in colder regions are heavier in

There is an animal in the Arctic Ocean called a Narwhal. There are three of predators for Narwhals. There predators include Killer Whales, Polar Bears, and Walruses. Narwhals can weigh up to 4,200 pounds! Narwhals don’t have a certain color for their whole life, they change colors! When they are born they are blue and gray, Juveniles are black and blue, and adults are mottled gray. Narwhals will eat Greenland halibut, Arctic and polar cod, squid, and shrimp. A Narwhal's tusk is actually an enlarged tooth with 10 million nerve endings inside.

2The Inuits have to understand the natural patterns of the wild life so...so it is easier to hunt prey like seals,caribou, and walrus Because there is ice that can expose them. But global warming is disrupting these patterns.

One man's trash is another man's treasure as the old adage goes, but what about when one man's trash is another species pandemic. Pollution has been plaguing humans for centuries, and as a result, the accumulation of this garbage has begun to significantly affect populations other than human beings. A striking example of this is found in Arctic Polar bear populations which as of recently are beginning to display some eerie side effects. Most individuals tend not to think about where their trash goes the second it leaves their hands, but it has to go somewhere. This somewhere is often times the ocean where the trash congregates and migrates around the world where it is consumed by the various species which dwell in its depths. The concentration of these toxins builds slowly within the various species that are exposed to it. Consequently, these concentrations increase as one moves up the food web, and at the top of the Arctic food web sits the beloved polar bear which bears the brunt of these ever increasing concentrations expressed through various health complications.

With the ever rising global temperatures, melting ice caps, and constant warnings about global warming, it is no wonder that the animals inhabiting the artic regions around the world are now suffering a decline in their habitat as well as their livelihood. Such is the case with the Polar Bears who may soon be gone in a scant few years.

The Poorly Informed Walrus is a fable that helps the reader understand the importance of effective communication. It starts out by the chief, asking the smaller walruses how the day catch was going. The smaller walruses did not want to reply because of their fear with the undesired amount. The chief “was the biggest and wisest walrus in the herd, and he knew his business, but he had such a terrible temper that every walrus in the herd was terrified of his ferocious bark”. (Uhl-Bien, Schermerhorn, & Osborn, 2014) They also remembered how the chief acted the last time they had not done well and did not want him to know of the disappointment this time. After some deliberation, Basil who was next in charge answered by saying all was well and that

The polar bear lives up in the Arctic region where global warming and climate change are melting the ice caps that the bears thrive on. They use the ice as a platform from hunting and rest. The random pocket holes in the ice, where the seals pop up at, is where the polar bear catches its prey. With this reduction of ice, “the abundance of seals, and increases the amount of energy and time needed for hunting, leaving less energy for reproduction” (Endangered Species and Habitats).

These mammals are quick learners, and respond more quickly and accurately to new experiences. Calfs stay with their mother for over a year just to learn by play how to behave in their pod and how to hunt. When one dolphin learns something new, they teach it to another member in their pod ("Rohan, Anuschka"). To "conserve energy [, they swim] alongside ships, a practice known as bow riding" ("Defenders of Wildlife"). Dolphins hunt together by surrounding their prey quickly after one dolphin stirs up the mud, "mullet are trapped by the dolphins unable to breath due to stirred up mud" ("Rohan, Anuschka"). Snow is a form of water and snow is also the terrain an arctic fox is pictured

The walrus can be found in the North Pole, Alaska shores, and Russia. Most walrus live in the North Pole. Some walrus’ swim to Alaska shores and Russia. Walrus lives on land too. You thought they just stay in water. Well you guys are wrong, they need air to breath because, they are mammals.
