Task 1 Can polar bears and people coexist? Polar bears are the largest land predator on earth today. They live in the Arctic area‚ surrounded by the northern nations like Norway‚ Greenland and Canada. The effects of global warming have caused the temperatures to rise‚ which have led the Arctic ice to melt. Because the polar bears’ territory is shrinking‚ they are forced to hunt further inland. They usually hunt on the sea ice‚ but they cannot do that now. A polar bear can starve for months‚ but

Besides‚ the Extreme Ice Survey‚ which this film documents seems very much a team effort‚ even if Balog’s sensitive eye endows it with an esthetic grandeur reminiscent of Manufactured Landscapes‚ another movie that looks over the

impacts that global warming is having on the earth. Studies have shown that the arctic sea ice is decreasing in size yearly. The red outline in the picture to the left shows how large the Polar Ice Cap was in 1979. The white are in the picture is how big the Polar Ice Cap currently is‚ that’s a significant decrease over just thirty five years. The thinner the ice gets the faster it melts. Besides the shrinking‚ the arctic sea ice is also forming later and later every year. This is directly impacting

Warming is causing the people in the Arctic to fight for the useful resources underneath the melting ice.It is most effective in the Arctic than anywhere else‚ it is affecting many people in the Arctic‚ and is causing people to fight. The ice in the Arctic is melting extremely quickly and it is making people fight and get injured or die. Global Warming is most effective in the Arctic. According to https://newsela.com and http://www.cfr.org the ice in the Arctic is melting faster than anywhere

The Arctic: Environment‚ Economic Development and Security Although many definitions are available‚ the “Arctic” is everything North of the 60th parallel of northern latitude. Canada has three territories and several tips of other provinces which total 40% of Canadian landmass that fits the definition of the Arctic. In this landmass‚ an estimated population of more than 100‚000 Canadians call it home. (The Canadian Arctic‚ 2013) This land and these people have needs and desires that are up to the
