A study done by the San Diego Zoo conservationists, they tested if land based foods were enough to fill the needs of wild polar bears to live. The problem they had to find an answer to was if the polar bears were able to adapt to the land based food and be able to balance their calories to not starve. Their hypothesis was that the polar bears would be able to adapt to the different type of food when they were fasting. This hypothesis was proven false because the polar bears that were fed food were losing weight as fast as the polar bears that weren't fed. The independent variable and dependent variable was how many calories the polar bears would intake as the IV and the DV being the bears weight lost. They compared the un fed bears to the bears …show more content…
I say this because of global warming. Global warming is making the world warmer and who is causing that? It is us humans, we are causing all the ice to melt. It says in the article that the polar bears that are on their own are losing weight at the same rate as the bears that are held in captivity, because the ice in the bears homes are either gone or to weak to hold them so they can't go out and catch seals or fish. Also this is important for the public to know because it brings attention to polar bears. What I mean by this is that the polar bears are becoming almost extinct. When animals are almost extinct humans usually do what they can to help save that species. This is like the African elephants they were on an extinction watch list so humans stopped hunting them and left them alone and let them repopulate. Finally, this is important for the public to know because it lets all of us know how nature is getting messed up. When polar bears can't get the food they need like seals they are kinda forced to go hunt little land animals. When this happens it takes more little animals to feed a polar bear so they are just going around eating all the little animals messing up their population and another food chain. To conclude this is important for the public to know because it shows how humans are affecting the polar bears with global warming, raising awareness for the polar bears, and how the polar bears can mess up a lot of other population because it can't get the calories they
For years, we have heard of the devastating effects of global warming and how the melting of the polar ice caps will cause severe climate changes. One animal that has suffered most from global warming is the polar bear. Global warming has caused the polar bear population to decrease due to the results of having to swim longer distances, loss of habitat, and lack of mates to reproduce offspring. Global warming has caused this species to become endangered and has some attention with social media. Global warming has caused much damage to the polar bear population due to the warming of their habitat.
Many hunters argue that the protectiveness towards grizzly bears is oriented more towards emotion than environmental sustainability. Researchers at the BC Raincoast Conservation Foundation have been devoted to fighting the hunt for over a decade now. Although they do signify that emotion is a part of their reason for banning hunting bears, they like to focus on the ecological and ethical aspects of the hunt. There is a big controversy over the fact that if there is a sustainable number of bears in the environment and people are allowed to kill them, then why is the surplus of humans allowed to grow?
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).
There is a long list of endangered animals. On that list is the animal I am currently researching, and that is the polar bear. Polar bears are animals that mostly lives in the North Pole and other ice covered oceans. The mass of an adult female polar bear is 330-350 pounds and an adult male is 990 pounds. Their speed is twenty-five miles per hour and the height of an adult female is 6.6 feet (on hind legs) and an adult male is 4.4 feet at shoulder (or all four legs). Also, polar bears can weigh as much as a grand piano. Their life span is about 20-30 years.
* Perhaps the most noticeable and striking characteristics of a polar bear is its color. The fur shafts themselves are not white. The shafts actually lack pigmentation and are transparent which allows them to scatter and reflect light resulting in ideal camouflage in a world of ice and snow.
Earlier this year on February 17, 2018, I volunteered at the annual Polar Bear run, which was put on by Franciscan City Way. The Polar Bear run is one of Indy’s oldest races, and this year was the 36th year of racing. I volunteered on a bitterly cold Saturday morning as a Course Marshall, which means I helped guide the runners and walkers to make sure everyone stayed on path. Luckily, I was near a corner where a cop had to block off the street, so she let me sit in her warm car until the racers appeared. I volunteered for this event as a part IUPUI’s Pre-Dental club. My ultimate career goal is to graduate from the IU School of Dentistry here on IUPUI’s campus and maybe even specialize in orthodontics. I fulfill my role as an active member of
In recent decades, the global warming threat has captured the attention of the nation and the world. While the main focus began with concentrating on the effects this long-term natural crisis would have on the human population, select groups have worked to approach the topic in a manner that entails prevention in order to help other animal and plant species around the globe. One such organization is the National Oceanic and Atmospheric Administration, which has played a major role in the conservation of the polar bear species, one of the mammals most adversely affected by the recent climate changes. As more research has been conducted regarding the polar bears, scientific name Ursus Maritimus, the conclusions have been shocking. In 2008, the Department to the Interior listed the polar bear species as “threatened” under the Endangered Species Act of 1973 awarding it some protections mandated by the federal government (Wolfe). However, on January 5, 2011, Representative Donald Young proposed a bill in Congress in order to delist the polar bears as threatened, thus decreasing and even removing the conservation efforts that have been set in place over the past three years. The polar bear Species should remain listed under the Endangered Species Act because ice thickness has decreased 40 percent during the past 30 years thus reducing the polar bears’ critical environment, if current conditions continue the polar bear populations around the world may decrease by two thirds by mid century, and since the species has been protected under the Endangered Species Act the worldwide populations have experienced stabilization or growth in most circumstances.
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
Until now, there is not a certain answer to how many grizzly bears are left in British Columbia. With approximation ranging from as low as 6,000 by individual biologists to as high as 15,000 by the B.C government, grizzly bear populations are therefore controversial. The reason why official estimates cannot be trusted is that the method used is suspicious since the government only applies a predictive model based on ground surveys conducted in only a limited number of areas. One of the independent scientists, Kyle Artelle, suggests that “more bears were being killed than government quotas allowed.” (thenarwhal) Serious situations, such as extinction, could occur on this species if trophy hunt in addition to other dire scenarios such as declining stocks of salmon along coasts and danger of road and railway accidents proceeds. Even though it is nearly impossible to eliminate all harmful causes of the depopulation for grizzly bear, the prohibition of trophy hunt can be easily taken into action to mitigate the negative trend. Additionally, grizzly bears are being an integral part of the ecosystem where they live. In case the grizzly bears die out, the ecosystem will become chaos. (pacificwild) For example, the speed of seed dispersal of many plants and berries will be reduced, the ocean-derived nutrients will cease to be transferred into inland to make
The one way to keep bears and humans safe and living in the same environment is learning to understand them and being able to tolerate them. If people don’t do these things theses beautiful animals will begin to decrease in numbers. While there are a lot of black bears in Alaska, an estimated 100,000, hunters believe that you can just hunt and hunt and the population will decrease to average, but the plans of some hunters seems just over the top of making these bears go on to the endangered species list. But with the help of people and cooperation the Black Bears will continue to live in Alaska.
Unfortunately, that is the polar bear (Defenders of Wildlife, 2013). The climate change endangers the species, so much so that the animals have become one of the icons that conservationists use to illustrate the threat posed by climate change (The Huffington Post, 2014). You cannot protect a species from the impacts of climate change without addressing the issue of climate change, itself (Defenders of Wildlife, 2013). Large carnivores are extreme indicators of ecosystem health (WWF, n.d.). “As the Arctic sea ice melts, the polar bears lose their primary hunting ground — not to mention their most plentiful and nutritious prey. It remains a question whether they will be able to adapt to changing conditions and survive” (The Huffington Post, 2014). A polar bear at risk is frequently a sign of something wrong somewhere in the arctic marine ecosystem! A polar bear at risk is frequently a sign of something wrong somewhere in the arctic marine ecosystem (WWF, n.d.)!
In the world where people live in is an enormous responsibility but also the greatest gift that people need to cherish and protect. The human race needs to step up and voice not only their concerns, but the concerns of all the animals endangered or not. Any species which fall into the categories vulnerable, endangered, or critically endangered are considered to be at risk of extinction. {Robert Redford} said “I think the environment should be put in the category of our national security defense of our resource’s because it’s just as important as defense abroad otherwise what is there to defend?”
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
Polar bears prefer to live in extremely cold artic climates. They live only in the Northern Hemisphere, on the arctic ice cap, and they spend most of their time on coastal areas. Polar bears are widely spread in Canada, extending from the northern arctic islands south to the Hudson Bay area. They are also found in Greenland, on islands off the shore of Norway, on the northern coast of the former Soviet Union, and on the northern and northwestern coasts of Alaska in the United States.
The polar regions are most affected and vulnerable to the warming temperatures because the poles are covered in ice. The world’s ice sheets are melting faster than ever and temperatures in the Arctic region are rising twice as fast as anywhere else on Earth according to the NRDC. This will have a serious impact on people, wildlife and plants in that region. The National Climate Assessment has said that “By the year 2100, it 's estimated our oceans will be one to four feet higher, threatening coastal systems and low-lying areas, including entire island nations and the world 's largest cities, including New York, Los Angeles, and Miami as well as Mumbai, Sydney, and Rio de Janeiro”. Polar bears are in great threat as the ice sheets melt because they use the ice to travel across the land and hunt. As the sea-ice platforms move further apart, the swimming conditions become more dangerous. The U.S Geological Survey done by the National Wildlife Federation predicts that by the year 2050, two thirds of all polar bears will disappear. Researcher Bill Fraser has tracked the Adelie penguins in Antarctica and reported the numbers have fallen from 32,000 to only 11,000 over the last 30
