characteristics of a polar bear is its color. The fur shafts themselves are not white. The shafts actually lack pigmentation and are transparent which allows them to scatter and reflect light resulting in ideal camouflage in a world of ice and snow. * Polar bears paws are also well adapted for the environment in which they live. They can measure up to 304 mm. (12 inches) in width. These large paws allow polar bears to better distribute their weight more evenly across ice surfaces. * Polar bears do not hibernate

Polar bears have been threatened in the past by unregulated commercial and sports hunting in the 1960’s and 1970’s. They were being wiped out quickly with modern methods of hunting, including aircraft, and were facing a huge loss in their population. Fortunately the 1973 Agreement on the Conservation of Polar Bears was established which was signed by Canada, Norway, Denmark (for Greenland), the United States

2012 (NASA, n.d.). This essay will examine the main effects of global warming by looking at the threats to wildlife and habitat, rise in sea level, and health impacts on humans. One main effect of global warming is the threat to wildlife and habitat. The increase in global warming disrupts wildlife species and causes extinction to animals that cannot adapt (NRDC, n.d.). One example is the decrease in polar bear population. As the ice continues to melt, some polar bears are drowning because
Essay Title: Polar bears are endangered Polar bears are one of the countless species who are endangered. They were one of the first animals affected by global warming and their population is heavily decreasing. Around 1980, the Arctic was as large as 8 million square kilometres. In 2011, studies show that the Arctic has reduced its size to 4.5 million square kilometers. In the future, will there be anything such as the Arctic? Scientist predict by 2040, only a fringe of ice will remain in Northeast
The essay opens up with McKibben talking about how the political campaign against global warming is flawed because at our current point there is nothing much that can be done to fix it.(Mckibben,1) He then goes to state that humans are the biggest culprit behind global warming and supports this by giving examples such as SUVs and American ignorance.(2,9) He concludes by saying that if ten percent of America were to go green, it still would not save the planet, but ten percent could get the government’s
