Description The poles are the remotest location on earth. Humans only ventured there for the first time about a century ago. Yet humans have still managed the change them. Global warming is magnified in the upper latitudes. If the temperature of the planet rises one degree, chances are, the poles have risen four degrees. Permafrost that buildings stand on, and ironically, the Alaskan Oil Pipeline, now shift in detrimental ways because the ground no longer stays in place. Natives find it harder to follow the food, such as caribou, and the animals themselves are not suited for the marshy ground that appears during the summer. Polar bears who depend on the arctic ice sheet for their favorite food, seals, have to swim out to the receding ice, and it has been estimated the only polar bears left in the year 2100 will be in zoos. Molecules that do not degrade such as DDT and mercury collects in the fat of animals, especially the ones at the top of the food chain such as humans and Orcas. The Arctic and Antarctic lands are some of the most spectacular areas on the planet. Scientists are discovering a surprising number of organisms thrive in these environments. Only by changing our ways in the temperate zones, we can save these lands. Helpful Websites
