Why Does Alaska Have To Import Its Food

The Earth's rise in temperature is melting ice in its colder regions. Many animals who live in the Arctic Circle, the lands surrounding

Though they both live in the Mackenzie Delta, the Inuit have the northernmost part of the Delta. The Inuit live in the Arctic in places like Nunavut, and Greenland. The Inuit also hunt seal, because they reach more land that is next to an ocean. Adding on to the previous statement, the Dene scarcely even touch the ocean in their own territory, except for the Hudson bay. This being said, the Inuit can eat animals like seals, and walruses, while the Dene eat land animals like moose, and bunnies. The Inuit can also be contrasted in what water they are near.

Ice and snow. The snow is slippery and wet in alaska so that makes it hard to travel. So instead of going on boat they had to go on foot because the ice was so hard. The mountains are hard too, it’s hard because it’s hard because you had to climb the mountains to get to there destination so with tons of supplies they ha to climb the mountains and walk thousands of miles especially on the ice and snow and the snow is more than 12 feet high and even on the mountains it is slippery with the ice so they could fall with all the weight on their back . when people travel on foot in Alaska it is hard because the snow and ice and when you were walking thousands of

Inuit communities are exempted from seal product restrictions and are allowed to hunt up to 400,000 seals ( a quota set by the government)

The inuit have to understand the natural patterns of Arctic wildlife because of global warming. Global warming is causing problems because the number

Humans have been interacting with the Arctic tundra for centuries now. They have used the land to explore and race, for example, the infamous race between Admunsen and Scott to the South pole. However, the human civilisation on the Arctic tundra have had their implications, both severe and light. Humans have slaughtered whales and seals since very early days, for food as well as commercial and self-profiting purposes. The most recent and paramount problem is global warming and pollution, which is harming the Arctic Tundra far more than the sealing and whaling ever did.

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

Another point he makes is that Polar bears are getting scrawnier because the seal habitat has declined because global warming causes the ice to melt. This is false. A common fact global warming supporters forget to mention is that arctic and Antarctic snowfall replenish the ice each year. Polar bears and seals are more in danger of poaching than losing their habitat to global warming. Both species are on the endangered list. However, weighing anywhere between 775 to 1,200 pounds. Polar bears are still the largest species of bear living on the planet.

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.

The first effect that global warming is having on Alaska regards coasts and oceans. In the northern summer, the sea ice is decreasing faster than previously recorded and it is foreseen to melt before mid-century (Chapin, F.S 2014). Solid ice is disappearing as there are no longer massive icebergs during fall and winter,

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).

It contains an expanse of tundra with many marshes and lagoons with rivers situated between foothills of the Brooks Range and the wide, icy waters of the Beaufort Sea. Environmentalists said that this area “is the most biologically productive part of the Arctic Refuge for wildlife and is the center if wildlife activity.” The importance of these resources is not measurable. The Arctic is home to such animals as caribou, polar bears, grizzly bears, musk oxen, whales, wolves and snow geese. This area is full of wildflowers and contains water of excellent, unpolluted quality and quantity. The Arctic Ocean costal plain is an area critical to the survival of many birds and mammals (‘Alaska Wild’).

Kolbert provides compelling evidence of Global Warming in the Arctic from her hands-on experience accompanying scientists in the field. From the storm surges that threaten the Alaskan village of Sarichef to the warming (and even melting!) permafrost, the evidence all point to the irrefutable fact that the planet is warming up extraordinarily fast. In fact, the Keeling Curve gives us a rather explicit visualization of how greenhouse gases levels (CO2, in particular) are rising at unprecedented rates.

Polar bears are the most known animals for the impacts of climate change on species. Global warming has been most prominent in the Arctic, and this trend is expected to continue. Their dependence on sea ice makes them highly vulnerable to a changing climate. Polar bears greatly rely on the sea ice environment for traveling, hunting, mating, resting, and in some areas, maternal dens (WWF). Specifically, they depend heavily on sea ice-dependent prey such as seals. Additionally, their long generation time and low reproductive rate may limit their ability to adapt to changes in the environment. Every time people breathe or burn something, oxygen in the air is converted to carbon dioxide. The carbon dioxide is used by plants to breathe and is converted back to oxygen, creating a cycle. If there is an increase in oxygen burning, for example, burning a lot of coal or oil to generate electricity or run cars, and cut down trees, the amount of carbon dioxide in the air is increased. This makes the air thicker and warms up the earth. The amount of warming is only a few degrees but it is enough to disturb the fragile balance of nature, which in turn will melt the polar ice, raise sea levels, cause violent hurricanes and endanger species such as polar bears. The polar bears are just one example of endangered animals because of the high demand of human need for energy which is acquired by burning fossil fuels.

The melting ice caps are having a dramatic affect on the polar regions of the earth. For example, the average temperature in the Arctic is rising twice as fast than the rest of the world (nrdc.org). The once prominent ice is now melting at a dramatic speed, which is affecting native people, wildlife, and plants. When the Ward Hunt Ice Shelf splintered, the freshwater lake that it surrounded drained into the ocean, along with the ecosystem that inhabited it. Polar bears, whales, walrus and seals are changing their feeding and migration patterns, making it harder for native people to hunt them (nrdc.org). Because of the flooding, entire villages will be uprooted order to avoid being swamped. Also, the Arctic coastlines are beginning to move as well. The melting ice caps are threatening the native peoples’ cultural identity and their very survival. Ice-dependant animals, such as walruses and ring seals will be greatly affected by the melting ice caps (treehugger.com). They have fewer places to rest on, as well as fewer places to hunt. If the ice caps keep melting, their lives will become in great danger. The melting ice caps are not only affecting the Polar Regions, but they are also affecting the rest of the world as well in the form of rising ocean levels.
