Introduction
Someday in the near future the world as we know it will be covered in snow and ice. Accurate, scientific calculations predict that by the end of the century, humans will be forced to live in the Arctic. In order for humans to be cable of living in these harsh climates, homo sapiens will need to develop new characteristics to their bodies. There will be three main body systems that will have have to be altered so the human population can survive, the integumentary, circulatory, and digestive system. First of all, humans would need to adapt a thick layer of blubber to keep warm, similar to polar bears and other Arctic mammals. In addition, have a stronger digestive system enabling humans to eat raw food. Lastly, the human race will

Blubber is a thick layer of fat between skin and organs. In addition, blubber also allows polar bears to be very buoyant and also keep their body temperature stable. Blubber is very vital because the Arctic reaches extremely low temperatures and blubber protects and insulates body heat by keeping the warmth in and keeping cold air or water out (Conservation Institute, 2013). Humans will require many traits to be able to prosper in the arctic but blubber is the most important, why? Well in order for the human population to withstand the Arctic, especially when the temperatures are much lower than the current human body is accustomed to. With a new layer covering the human body, humans will have a much easier time living and thriving in the Arctic …show more content…
Animals such as polar bears have substantial stomachs in order for them to eat excessively fatty foods. A polar bear’s diet consists of animals such as whales, belugas, and other marine mammals. One of the few traits that these animals have in common is their great deal of fat and polar bears have the strength in their stomachs to digest these foods. (Zoologist, n.d). The fat and protein filled animals are foods that humans will need to endure the arctic. But with the current digestive system, there is seldom chance to bear the new earth. With enhanced stomachs, humans will be able to digest the food currently in the
The Arctic Tundra is the biome where the Polar bear, Ursus maritimus, or the sea bear live. The climate over there is in the Arctic and is Earth's coldest, where it is treeless and covered with piles of snow and ice for the whole year until summer when it brings wildflowers. On the top of the mountain it is colder, windy, and rainfall is scant.
The Arctic Sun is an experimental study but has various supporting data. When a person such as L.E. experiences a heart attack, one of the body’s responses is increased body temperature. Increased body temperature contributes to ischemic brain damage post cardiac arrest. The Arctic Sun is a system that provides targeted temperature management for the neurologically impaired patient. Pads are placed on approximately 40% of the body and a temperature probe is inserted.
Various glaciers in Alaska and other parts of the United States have shrunk dramatically. If temperatures continue to rise, the ice will continue to melt, and some glaciers could disappear completely, which causes sea levels to rise. There are many animals, birds, and seafood that depend solely on glaciers for survival. With an increase in sea water temperature, and increasing sea levels, sea-plants that these fish thrive on will be lost, lowering the number of seafood, which in-turn will make survival of many species difficult. The arctic is source region for cold ocean currents and with no ice it will have no density and temperature distinctions, which pushes the ocean currents. If the ocean current heat transfer mechanism powers down,
The environmental pressure of the Pleistocene ice age caused a fast evolutionary jump from the species of Grizzly bears to Polar bears. The climate an animal lives in plays a large part in the composition of an animal. The availability of prey is one of the most crucial parts of survival. Mutations of species can impact them or die off quicklier.
Out of an Ice Age emerged one of our most majestic creatures in the world the polar bear. From its brown bear ancestry, the predator evolved to be a master of a harsh and unwelcoming ice kingdom. Intelligent, adaptable and fierce, the polar bear learned how to survive in a place that offers few comforts to any creature. But now that very environment is in flux. And so is the polar bear’s fate (Nature). Polar Bears are very different from other bears. Polar bears are very large bears compared to Black bears. Polar bears weigh anywhere between 330-1700lbs and Black bears weigh anywhere between 150-600lbs. They have strong legs with large, flattened feet with some webbing between their toes that help with walking on ice and swimming. The wide paws prevent sea ice from breaking by distributing weight while walking. Their paws allow them to pull a 600 pound seal out of its breathing hole (Rosing, 20). The webbed feet results in making polar bears, unlike other bear species to be considered as marine mammals along with seals, sea lions, walruses, whales and dolphins (Polar Bear). According to Rosing Polar bears are excellent swimmers and have been known to swim up to six miles an hour and as far as 60 miles at a stretch. The bears paddle with their front feet and steer with their back feet. They often overheat. Sometimes they venture into the waters just to cool off. When a bear climbs on an ice floe, it shakes itself off because it is trying to prevent ice from forming on its fur (22-23). Because of climate change and hunting of polar bears are now becoming an endangered species which is affecting the food chain. We can fix this by going green, banning polar bear hunting and keep creating these new hybrid bears that are mixed with griz...
To survive it would be easier to know the environment. The Arctic is a system of deep ice covered and nearly isolated ocean, surrounded by lands of Eurasia and North America. It has ice glaciers, plains (of ice), coastal shallows, deep basins, polar
* Polar bears are members of the bear family Ursidae. They are a carnivorous bear which can be found throughout the Arctic region where they rely on sea ice to sustain their hunting activities. Canada hosts approximately 60% of the polar bear population. Other areas inhabited by polar bears include Alas...
Polar bears don't just live on ice, they use the ice as an advantage to catch prey such as seals. Polar bears have adapted to living on ice and being able to withstand the cold weather. Now that the climate is changing at a fast pace, polar bears are losing their land because its melting, leaving them with no place to walk, sleep and taking away their way of hunting prey. (polar bears international, 2015) This is all happening so fast that there is no way polar bears will be able to adapt to the new environments, causing extinction. The arctic is warming twice as fast as the rest of the world is due to the build up of greenhouse gases in the atmosphere, making it a problem happening very rapidly. (Bagley, 2015) Temperatures in the Arctic region have risen 7 degrees Fahrenheit over the last half century. (Bagley, 2015) Population among polar bears has decreased up to 40% in some areas. (Bagley, 2015) With the climate getting warmer, ice is melting earlier every spring, and takes longer to freeze every winter which is disrupting the feeding and breeding cycles of many different arctic species. (Bagley, 2015) Polar bears have adapted ways to survive in the cold harsh arctic environment including having the ability to cool down their outer skin to keep their vital organs warm when they are submerged in cold water. Though this may help the delay of hypothermia as they have to swim greater distances from ice shelf to ice shelf, that doesn't mean polar bears can swim forever. (Bagley, 2015) One bear that a scientist studied swam 500 miles over nine days, but lost 22% of her body weight, and lost her cub.(Bagley, 2015) Many different scientists have been studying the behaviour of the polar bear to see if it could adapt in any way to survive. Eight U.S scientists made a hypothesis consisting that polar bears could lower their metabolic rates enough to survive as food
Years before electricity or any modern technology entered the Arctic region; The Inuit lived in circle domes called "igloos". There were no wood available out where they lived, so they had to get creative and use the snow that surrounded them. In which they had molded into gigantic blocks as a substitute instead. During the summertime they traded out their igloos for tents as shelter. At times they would add animal skins on their tents if it wasn't warm e...
The habitat is also made up of trees with nuts and bushes with berries. Black Bears are omnivores so they eat these along with other small animals. They are opportunist when it comes to food. Mostly bears eat vegetation during the spring but they will eat mainly anything they encounter. During the summer the bears eat salmon out of the rivers if they can catch it. If they can’t catch any they mainly survive off of berries, mainly blueberries, ants, grubs, and other insects. In the fall their diet starts to shift and they start to save up food for winter. They are also known to eat newborn moose calves during the winter when food is scarce.
Climate change is influence the health of Alaskans in a variety of ways changes in the environment and ecology are resulting in new or increase threats to water quality or quantity as well of changes in the incidence of certain human and animal conditions. Rural and indigenous communities are faced with growing concerns over economic, health and cultural impacts due to climate change related declines in the availability of plant and animals
The members of the Homo genus possess a combination of unique features that distinguish them from other related species. At the time that each respective species was alive, they were able to walk upright on two legs, use their large brains for the benefit of their species, and could thrive in many geographically and climatically diverse areas of the world. One of the most mysterious quandaries in science is how the lineage of the Homo genus became so different from their primate relatives. Bipedalism, brain size, and location diversity all have a common link that may explain this difference – dietary evolution allowed humans to adapt to their surroundings, and in turn, become a more advanced species. The Homo diet evolved in relation to food availability and nutritional necessity. With the ability to maintain a proper diet, the species of the Homo genus were able to flourish and advance toward the development of modern Homo sapiens.
However, there is a lot of damage done to the body during this freezing, says Dr. Ralph Merkle, a professional in the field of cryonics. First there are fractures that form in the frozen tissues caused by thermal strain, if you were warmed up you’d fall into pieces as if cut by thousands of sharp knives. And Second, the Cryotransport is used as a last resort because legally the Cryotransport can’t even begin until the patient is legally dead. So when the patient comes out he is already sick and may have a hard time coming back from the injuries of being frozen. Even after knowing all this Dr. Merkle says Cryotransport will almost surely work. Why? He says because basically people are made up of molecules and if they are arranged right then the person is healthy, if not the person is either sick or dead. With technological advances he thinks we will be able to make and rearrange the molecular structure of the frozen tissue. In the future, we will be able to stack and unstack these molecules like Lego blocks. Once the molecules are arranged correctly the person is healthy.
The Arctic region is home to a variety of valuable animals and plants, including polar bear, seal, and so on. The ecosystem of the Arctic region is fragile because these animals are evolved to live in extreme conditions. With the climate change, many animals are endangered. Ice is the habitat of polar animals because they have to rely on sea ices for resting, food, and reproduction. With the climate change and the decrease of sea ice, the number of polar animals is decreasing and their health is threatened. For example, the average weight of female polar bears in 1980 was about 650 pounds, but the number reduced to about 500 pounds in 2004 (Djoghlaf 15). The earlier breakup and later condensation of sea ice shortens the hunting season of polar bears. Polar bears mainly feed on seals that indwell icy land. The melting ice reduces the number of seals and food intake of polar bears. In addition, polar bears are used to living in ice caves. The rising temperature causes the collapse of ice caves, which can kill baby bears. The climate change is negatively affecting the biodiversity in the region and will definitely harm the ecosystem
The polar bear rarely eats plants. That is why it is considered a carnivore, or meat-eater. The ringed seal is the polar bear's primary prey. A polar bear hunts a seal by waiting quietly for it to emerge from an opening a seal makes in the ice allowing them to breathe or climb out of the water to rest. Polar bears eat only the seal's skin and blubber of the seal. The remaining meat provides a food source for other animals in the Arctic.
