Save The Polar Bears Summer Sea Ice

Sadly the global warming is going to be taking quite a few victims along with it as it comes, within the next 10 years about one third of the entire world’s polar bears are in danger from greenhouse gas emissions, U.S government report states. Greenhouses gases are the cause of climate warming and in result reduction of the polar bear’s summer sea ice habitat.

The loss of this ice will lead to drastic population decreases in the polar bears and scientists are predicating no rebounds in the population in their projections which are going up till 2100.

Alaska is the only state in the nation with polar bears, and after the U.S Geological Survey was conducted the Interior Departments researchers said that scientific models don’t bode well for the white bear populations in the world.

The U.S has launched a Fish and Wildlife Service’s Recovery Plan to help the polar bears from vanishing and the study is part of this plan , reports are going to be published on Thursday in the Federal Register.

The scientists derived a model which can help them predict situations in two instances; one in which the greenhouse gases are somehow controlled and decreased and the other if the situation goes on like it is right now.

Lead author Todd Atwood, an Alaska –based USGS research wildlife biologist, feels that each situation would result in the bears in Alaska, Russia and Norway, who are estimated to be 8,500, would start declining drastically by 2025-2030.

The cause of this is because Arctic has suffered some very drastic summer sea ice declines.

Polar bears main food is the seal and it uses sea ice for feeding, mating and giving birth. When sea ice retreats in the summer it forces the polar bear to be on the land and land based food is not enough for the white bear’s survival.

As recorded by the Office of Naval Research, the past eight years have seen the eight lowest amounts of sea ice on record.

The report did not put a number to the decline but measured it in terms of ‘ decreased population’ or ‘greatly decreased population.’

Atwood expressed his concern about the loss of polar bear population, saying that its not that we will completely loose the polar bears but there will be a greatly decreased distribution than what we currently have.

Canadian and Greenland polar bears will also see drastic declines by 2050, but white bears in the Canadian Arctic are so far the best off in terms of population decrease.

Alaska director for the Center for Biological Diversity states, “Polar bears are in big trouble, there are other steps we can take to slow the decline of polar bears, but in the long run, the only way to save polar bears in the Arctic is to reduce greenhouse gas emissions.”

After the eminent effects of global warming came into play, polar bears were the first animal to be listed under the Endangered Species Act in 2008.
