From 1987-2004 there has been a 22 percentile drop in the polar bear population. There are numerous reasons why polar bears are in tremendous danger extinction . Global warming is by far the most significant reason why polar bears are in danger but really we should be thinking who is responsible for global warming in the first place. While global warming isn’t the easiest to reverse there are other problems that can be solved very easily be solved. Polar bears are increasingly becoming endangered because of drastic changes in the air due to pollution and global warming in the arctic.
Polar bears are in tremendous danger and we are not doing enough to help. A lot of people either don’t know about polar bears or don’t care enough to help. The population has gone down so much because people are saying just let the next generation deal with it but the thing is they might not have another one so we need to do something now.

People driving everywhere is one of the main factors of global warming and the temperature going up. Driving is something we rely on so much and it is polluting the air which is causing the ice to melt. When people throw trash in the ocean the seals tend to eat it because the number of fish are going down. When the polar bears eat the seals they inject the plastic from their systems and the plastic starts to kill them. Since the Arctic has a lot of oil and we use a lot of oil they moved some of their businesses there and now the polar bears don’t have anywhere to live. The oil is leaking into the ocean which kills the seals so now they having nothing to survive on.Now that the oil businesses are booming it might take a long time to remove them because humans rely on oil so
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.
First, global warming has an immense impact on Arctic Sovereignty as the rise of greenhouse gases thrive in Canada along with other countries. Within 20 years, the polar ice caps of the Arctic have melted twice as fast compared to before. The loss of Arctic ice can furthermore pose a threat to shipping, as navigating the Arctic becomes increasingly challenging. Finally, climate change threatens the extinction of numerous animal species, namely the polar bear. Hence, global warming poses a major challenge to Arctic Sovereignty and Canada along with other members in the Arctic Council must prevent it.
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).
The effects of global warming on earth's ecosystems are expected to deepen. The rise in temperature had made the life very difficult for many animal and plant species. Some common warning signs can be seen today. A recent study shows that changes due to global warming compel many animal species to migrate at a higher altitude. Some polar bears in arctic side are drowning because they have to swim longer distances to reach ice floes. In California, shoreline, sea life is moving towards north, as a result of warm water and change in
Species are decreasing and becoming extinct over time due to climate warming. Animals and plants have developed and diversified from earlier forms to become more complex organisms. Not only have living organisms changed, but so has the Earth. Over time, the world itself has changed drastically, not just the climate but the way it looks as well. The ice on the arctic is melting, causing oceans to become more acidic, oceans became deserts and pollution from our everyday lives are affecting the ozone. It all adds up and changes the world negatively. When the world changes, so do the animals within it. Climate warming has been a big part of the change we see in the population of different species. The speed of climate change is excelling, which
On Thin Ice written by Susan McGrath explains the negative affects of global warming on polar bears. Green house gases being emitted into the atmosphere is causing the earth to become hotter. The ice that the polar bears live on continues to shrink because of rising temperatures. In 1979, there was approximately thirty percent more ice in the summer compared to now. Polar bears spend almost their entire life on the sea ice (McGrath). The only time that they go to land is to build maternal birthing dens. After the birth has occurred, the cub and mother need to make the swim back to the ice. Since the ice is melting, the polar bears swimming distance continues to grow. Polar bears are strong swimmers but these long swims can be fatal. A tracker on a mother polar bear showed that she and her cub had to swim 427 miles to reach the ice. The cub died during the swim (McGrath). The ice melting is also causing the polar bears to become skinnier. Polar bears losing weight is caused because of the long swims they have to make to reach the ice. Losing weight has a negative affect on their health. The health decline then causes polar bears to reproduce less and fewer of the cubs survive. Polar bears are no longer growing to be as big (McGrath). Since they are not as big, they cannot catch as much food. When males are hungry and malnourished they can turn into cannibals. They kill the cubs and sometimes females for food (McGrath). The question that arises is will polar bears be able to survive if temperatures continue to rise? Scientists believe that they would be able to survive in the short run but after a few years of not being able to live on the ice they would die. Polar bears dying will completely change the ecosystems that they live in ...
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.
“Those searching for unmistakable evidence of the global climate crisis should pay a visit to the Arctic. The Arctic is warming twice as fast as the rest of the world. The average annual temperature in Barrow, at the northern-most tip of Alaska, has increased 4.5 degrees Fahrenheit in the last 50 years” (Noblin, n.d.). Polar bears have been threatened in the past by unregulated commercial and sports hunting in the 1960’s and 1970’s. They were being wiped out quickly with modern methods of hunting, including aircraft, and were facing a huge loss in their population. Fortunately the 1973 Agreement on the Conservation of Polar Bears was established which was signed by Canada, Norway, Denmark (for Greenland), the United States of America, and Russia
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.)!
The negative side of global warming is that it leads to melting of ice. The world's glaciers, especially Arctic glaciers are melting faster than new snow and ice can supplement them. During the melting of Arctic ice opens over the dark surface of the water or soil and balance change reflects less and absorb a greater amount of heat, therefore, large areas of ice melt rapidly (News, global warming). There is evidence, which will support this argument: scientists from the University of California in San Diego investigated satellite observation data for the Arctic for 1979-2011 years. Since the 1970s, the area covering of the ice has decreased by 40 % and the region has warmed up to 2 degrees (News global warming).It means, that global warming affects to the wildli...
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
It is unfortunate that within the past 100 years our worlds' economy has driven itself into a deep hole with the reliance on a "black gold" called oil. Since its discovery, it has been purified to produce many different forms of energy such as light, gasoline and more. Since technology has enabled mankind to discover more capable methods of transportation, mankind has exploited its power over nature and produced machines such as the combustion engine. In combustion engine's, oil explodes to move machinery, and emits a very toxic byproduct called CO2. Carbon is incredibly dangerous to the earth's atmosphere, and erodes huge holes in the ozone layer of our earth. This erosion causes global warming and climate change that is permanent and irreversible. The impact of global warming will not only ...
There is an estimate of 1.3 million cars in the world, in the United States alone the ration from person to cars is 1.3. That 's almost 255 million cars in the roads every single day. Just imagine, “Burning one gallon of gas creates 20 pounds of carbon dioxide, and the average car emits about six tons of carbon dioxide every year”(Global Warming And Your Car).Imagine how many tons of Carbon dioxide are emitted into the air by everyone in the world. The carbon that gets emitted into the air doesn 't just affect the climate it also affects us by polluting the very air that we breath. Air pollution causes around 3.3 million deaths worldwide every year. One of the biggest places with contamination is China, the main reason for that is because of all of the factories that they have and all the carbon dioxide that gets let out.People and their decisions are the main reason for climate change, they only think about the present and never about the
The seriousness of global warming effects both the environment and the people living in it. The question is how do Americans effect the environment and what can we do to fix it? Americans everyday use automobiles as a form of transportation, and although it may seem harmless, the use of these cars are proving to be detrimental in the end. Author Margaret Kriz (2006) states that, “the vast majority of scientists who study Earth's climate agree that the planet is warming, and they blame the greenhouse gases that accumulate in the a...
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
