bleaching (a process by which coral reefs lose their life-giving algae) has become more widespread in the past decades as sea temperatures rise‚ causing reefs to “’collapse catastrophically’” (Markey). Colder regions‚ too‚ are feeling the heat. In the Arctic‚ shrinking sea ice is disappearing at a rate of 11% per decade‚ which has depleted polar bear habitats and shortened their winter hunting season‚ resulting in malnutrition and population decline(Dvorak). Meanwhile‚ on the opposite pole‚ the Antarctic

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
