She's also critical of teachers, saying boy 'was screaming for help'The bedroom bears the telltale signs of a typical boy on the cusp of his teen years: discarded food wrappers, video game consoles, clothes scattered on the floor.

Although every issue of importance in American politics affects someone somewhere, we are often inundated with discussion of issues that have little bearing on our daily, individual lives. Then there are issues that affect all of us but are rarely discussed.

"The reality is that despite some genuine economic growth abroad, governments are creating so much inflation that food prices are raising anyway." — Peter Schiff

Firstly there is the concern that the reduction of sea ice would lead to them not being able to hunt sufficiently to survive. Now another issue has been raised, one which affects the very food chain the polar bears are part of.

Polar bears in Canada's Hudson Bay area are battling for survival, as climate change reduces the time they can hunt for food, warn environmentalists and locals in Churchill, the self-proclaimed polar capital of the world.

The polar bear (Ursus maritimus) is a bear native to the Arctic. Polar bears and Kodiak bears are the world's largest land carnivores, with most adult males weighing 300–600 kg (660–1320 lb); adult females are about half the size of males. Its fur is hollow and translucent, but usually appears as white or cream colored, thus providing the animal with effective camouflage. Its skin is actually black in color. Its thick blubber and fur insulate it against the cold. The bear has a short tail and small ears that help reduce heat loss, as well as a relatively small head and long, tapered body to streamline it for swimming.A semi-aquatic marine mammal, the polar bear has adapted for life on a combination of land, sea, and ice, and is the apex predator within its range. It feeds mainly on seals, young walruses, and whales, although it will eat anything it can kill.The polar bear is a vulnerable species at high risk of extinction. Zoologists and climatologists believe that the projected decreases in the polar sea ice due to global warming will reduce their population by two thirds by mid-century. Local long-term studies show that 7 out of 19 subpopulations are declining or already severely reduced. In the USA, the Center for Biological Diversity petitioned to list the polar bear as an endangered species under the U.S. Endangered Species Act in 2005. The U.S. Fish and Wildlife Service formally proposed to list the polar bear as a threatened species on January 9, 2007. A final decision was due on January 9, 2008 but has been delayed.
