But if there is one species which suffers the most, they are the polar bears who can only survive under extremely cold climate. Although their actual population is hard to determine, they are believed to be around 20, to 25, found throughout the Arctic Ocean and adjacent seas World Wildlife Organization.
The area is said to have a fragile ecosystem, requiring longer time to change and to recover when disrupted or damaged. Get Essay However, research shows that the Arctic is most likely to be ice free between and for the first time in history. The region has been experiencing thinning of the polar ice cap due to warming of temperatures. With the melting of the ice comes the destruction of the life of the species which thrives in the Arctic. Polar bears, seals, including endangered species like walruses and whales, are forced to retreat to environment less suitable for their make up.
Further, scientists fear that large amounts of melted ice enter the North Atlantic and disrupt the global current pattern. The melting of the Arctic ice also entails smaller hunting area for polar 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 calorie requirement. Their body needs large amount of fats from marine animals for they are active year-round.
Reduction in Arctic sea ice can lead to 67 percent loss of the entire polar bear population in 50 years Bear Planet Organization. Though polar bears are exposed to other risks such as pollution, oil and gas exploration, legal and illegal hunting, global warming remains the biggest threat to their survival.
They experience malnutrition and starvation due to habitat loss. This means under the global warming, we may not know that the earth becomes hotter and hotter and realize it is a serious problem because we cannot feel it. However, the deep change is going on in the Arctic. The first victim is the polar bear. Furthermore, if the sea ice disappears, the temperature of the Arctic will go up extremely.
Louis Fortier, a scientist of a study group of Canada named Arctic, said that the Arctic sea ice cover has existed for about 3. The vanishing of the ice cover might lead to a higher speed of global warming tendency Campbell, The temperature directly determines the total amount of the sea ice.
On the other hand, when the sea ice is shrinking, more and more lights cannot be reflected to the space. As a result, the temperature rises again. The second change in habitat is the sea ice which covers the Arctic Ocean. Because of global warming, the sea ice has diminished. A huge change happened on Near 1.
Million square km of Arctic ice disappeared in that year beyond far away from formal yearly medial of 70 thousands Campbell, This huge change led more people worry about global warming and thus the polar bears lost their habitat. At this point, we will consider Global Warming, Polar Bears 4 about if the Arctic sea ice is gone in the future. Sea ice cover Of the Arctic decreased at the average of 1 1.
Lots of scholars hold the opinion that the Arctic sea ice cover will completely melted around Swift, 1. Through this research, we can imagine that the sea ice decreased quickly in recent couple decades and the serious coming effect. The last change in habitats is the food.
Polar beads main food is seal, but global warming disturbs this food chain, so polar bear is hard to find their food. Due to the increasing melting on ice, there is less place leaving to all the polar bears as well as his primary food seals. Both must live on the sea ice.
Because food is limited, polar bear need find other choice Cole, The longer summer melt season will destroy the entire Arctic food chain, especially causing the most serious effect to Polar bears McGrath, The melt season will influence polar bears to search food.
The longer melting season the more risk will happen on the polar bears. With the sea ice shrinking, the seal and polar bear both declined. Without enough food supply, polar bears are hard to survive from the cold place. For those reasons, the sea ice becomes to smaller and smaller, and the temperature over the Arctic is increasing to higher and higher and the food web is disturbed, there is few places leaving for the beautiful polar bears.
Polar bears inhabit the circumpolar arctic regions 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 I feel that it is crucial that humans intervene in the destruction of animals species and their habitats the same.
After all, most of the destruction is that of our machines and mass production. I mean what would happen to all the species that become endangered from our mistakes such as careless environmental endeavors. Did you know that there are many things that we could do to help, but people just put them to the side because they feel that it isn 't important to reduce, reuse, and recycle They are on the top of the food chain and have no other predators, and there strong bodies and layers of fat and fur allow them to survive the harsh conditions of the Arctic.
The Arctic is a large body of frozen water with layers of ice sheets and is filled with glaciers. The regional climate of the Arctic is mostly cold and freezing temperatures that range from to degrees Celsius in the winter to about a high of degrees Celsius in the summer It has diversities ranging from highly variant temperature and pressure belts as well as various ecosystem types.
One such remarkable feature of the earth is the polar ice caps.
World Wildlife Organization. The reduction of food supply is a key to polar bear deaths For finding food, polar bears swim very far distance beyond their abilities, so lots of they may drown in the sea. By , it was already underway. Due to the increasing melting on ice, there is less place leaving to all the polar bears as well as his primary food seals.
They must face the long moving trip even involve death. It has also been translated into German for a dedicated climate change issue 11 July of the Swiss weekly magazine Die Weltwoche. Since the temperature of the world increases dramatically, the sea ice over the Arctic region decreases quickly. By , it was already underway. Because of global warming, the sea ice has diminished.
Because food is limited, polar bear need find other choice Cole, The farther the bears have to travel to get on the ice to hunt the more weight they lose. Generally, the prime food for polar bears is seal.
There is abundant evidence that the world is becoming warmer and warmer. Because food is limited, polar bear need find other choice Cole, The second change in polar bears is mating. If this trend does not change in the following years, polar bears will extinct. As a result, there are no place to live and no food for polar bears. However, the deep change is going on in the Arctic.
The World of the Polar Bear. 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-hunting areas. Both must live on the sea ice. As a result, the polar bears loss their habitat and food.
The reduction of ice is causing the seal population to reduce and it is causing the bears to face starvation. Blood and urine samples were also taken. Currently, the population of the polar bears is estimated from twenty thousands to twenty- eve thousands bears by biologists. Further, scientists fear that large amounts of melted ice enter the North Atlantic and disrupt the global current pattern.
Although capable of swimming long distances, polar bears burn far more energy doing so than walking, a recent study published in Polar Biology found. At the food shortage times, they cannot feed their cubs very well. Blood and urine samples were also taken. As it currently stands, the US Fish and Wildlife Service consider polar bears as threatened species meaning anytime their habitat will vanish and their status will change to endangered before they ultimately become extinct. The melting of the Arctic ice also entails smaller hunting area for polar bears. It has diversities ranging from highly variant temperature and pressure belts as well as various ecosystem types.
Polar bears deserve a chance. If these results hold up, then it shows that the loss of sea ice may have a bigger impact on the bears than previously thought, said Amstrup, a former USGS polar bear expert. Generally, the prime food for polar bears is seal. The regional climate of the Arctic is mostly cold and freezing temperatures that range from to degrees Celsius in the winter to about a high of degrees Celsius in the summer
The longer summer melt season will destroy the entire Arctic food chain, especially causing the most serious effect to Polar bears McGrath, The melt season will influence polar bears to search food. Even today, in the middle of the bitter cold Arctic winter, satellites show there is about , square miles less sea ice than the to median That's an area larger than Alaska and California combined. Climate Change and Endagered Species Essay - What is the first marine mammal added to the endangered species list attributed primarily to climate change. Those polar bears walk around the trash dropped by human to find something to eat Cole,
More swimming could lead to smaller bears, reduced reproduction rates, and even increased risk of death—something already being seen in western Hudson Bay and around the southern Beaufort Sea, Griffen said. They are the only species aside from elkhorn coral and staghorn coral to be put on the said list. At the food shortage times, they cannot feed their cubs very well. I feel that it is crucial that humans intervene in the destruction of animals species and their habitats the same. They must face the long moving trip even involve death. To this day, these researchers and others continue to make such claims and falsely suggest that population numbers have remained at depleted levels since
The first victim is the polar bear. With the Global Warming, polar Bears 3 enrapture increasing, the sea ice over here melts quickly. So the point is here, to get enough foods is an essential thing of mating. Even if they will die, they may swim for long distance that they never have done before Cole, Million square km of Arctic ice disappeared in that year beyond far away from formal yearly medial of 70 thousands Campbell,
