Effects of Global Warming on Polar Bears Essay

No one is safe from the harsh effects of global warming. solitary(prenominal) if there is one species which suffers the most, they be the diametral bears who can only wear under extremely cold climate. Although their actual state is hard to determine, they be believed to be around 20,000 to 25, 000 found throughout the Arctic Ocean and close seas ( serviceman Wildlife Organization). arctic bears habitat is almost covered by sea screwball-skating rink all year round (Great watch Organization). The ara is say to rescue a fragile ecosystem, requiring eight-day time to change and to recover when stop or damaged.However, research shows that the Arctic is most likely to be meth free between 2013 and 2040 for the first time in history. The region has been experiencing thinning of the diametric scrap cap due to warming of temperatures. With the melting of the ice rink comes the destruction of the life of the species which thrives in the Arctic. Polar bears, seals, inc luding endangered species like walruses and whales, are forced to retreat to environment less suitable for their make up.Further, scientists hero-worship that large amounts of melted ice enter the North Atlantic and scatter the global current pattern. The melting of the Arctic ice similarly entails littler hunting area for cold bears. Seals are their favorite and they cannot track them where the sea is unfrozen. They also eat plants, including berries, roots, and kelp, but none of these can satisfy their small calorie requirement. Their body needs large amount of fats from marine animals for they are agile year-round.Reduction in Arctic sea ice can bullock to 67 percent loss of the entire polar bear population in 50 years ( confront Planet Organization). Though polar bears are exposed to other risk of exposures such as pollution, oil and gas exploration, efficacious and illegal hunting, global warming remains the biggest threat to their survival. They experience malnutrit ion and starvation due to habitat loss. Melting ice force them to shore beforehand they have acquired enough fat reserves to survive the period of unique food during the deeply summer and early fall.Thining ice are come in hard to walk on because they deform more easily which makes it more difficult for them to hunt for food. They also need to swim wider gaps between ice which further used up their energy and sometimes lead to drowning. give effeminate polar bears result to visit reproductive rates and lower survival rates among cubs and juvenilles (Rosing, 2006). Thining ice make it hard for adult females to dominate mates. And when they do find one, the hard quest starts for a suitable maternal quality dens.Underground dens have tendencies to collapse or have low insulative forefinger to provide heat for newly born cubs. Dens built on multi-year ice may experience movement that may result in longer distances for mothers and young cubs to walk when they return to seal-hun ting areas. There is also a risk of disease-causing bacteria and parasites to flourish more readily in a bullet climate. In Western Huson Bay, ice breaks up earlier than it did 30 years ago during late spring season which shortens the hunting season for polar nears (National Wildlife Organization).Their population declined by 22 percent from 1987 to 2004 and their body condition is much(prenominal) several(predicate), weighing 60kg lighter in 2004 than in 1980 when likely pregnant female polar bears weigh around 290kg. In 2005, Alaska recorded four drowned polar bears who made longer swim than they normally do when hunting for food. Alaska also documented higher mortality rates among polar bear cubs and different denning sites for pregnant polar bears. Photos and videos of polar bears struggle are everywhere.In 2008, US Department of the Interior listed Polar Bears as threatened species under the threaten Species Act and melting of the sea ice in the Arctic as the biggest danger to their survival (The Humane Society of the United States). They are the only species aside from elkhorn coral and staghorn coral to be put on the said list. However, the decision was reversed following the commercial and scientific data that they are increasing in numbers in the past 30 years.As it currently stands, the US Fish and Wildlife Service consider polar bears as threatened species meaning anytime their habitat provide vanish and their status will change to endangered before they ultimately become extinct. In Canada, polar bears were recommended by the Committee on the Status of Endangered Wildlife in Canada to be placed under the list of species of special concern. This list allows for a management plan to be written in five years, which was criticized by World Wide Fund for Nature as being similarly long to make a substantive impact to habitat loss from climate change.Since their current status is threatened species, it is not too late for efforts toward saving their habitat from further degradation (Bear Planet Organization). The simplest but the go around way to mitigate the effects of global warming is to stop century dioxide (CO2) emissions. Recycle and reuse products and use energy efficient appliances to cut rachis CO2 in the atmosphere. Polar bears deserve a chance. Works Cited Bear Planet Organization. Polar Bears and Global Warming.
