Polar Bear Invasion  北極熊的入侵
by Evan Witkowski

See inside the life of polar bears struggling to survive in one of the coldest places on Earth.

    Spending summers on land and winters traveling from iceberg to iceberg is not an easy life. Their fur helps them blend into their surroundings, but polar bears living in the Arctic are threatened by climate change more than being spotted by their prey. Melting icebergs mean that many animals are suffering from a loss of their habitats. Destination Wild's Polar Bear Invasion episode is the latest special from National Geographic Channel (NGC) that follows these bears on their journey to raise cubs in the harsh climate of the North.
  Unlike other species of bears, polar bears don't sleep through the winter months, and they spend their winters living in the cold and snow of the subarctic and Arctic areas. The crew of Polar Bear Invasion manages to follow several bears relying on their instincts to travel around the icy, snow-covered landscape. Seeing up-close how polar bears live, and the challenges they overcome every day, really illustrates how hard life is for these animals.
  From late fall, polar bears migrate north to the ice floes of the Arctic to hunt for fish and seals. They can only swim for so long before they run out of energy, so the melting icebergs are a serious problem for polar bears. If there is less ice, then the bears have nowhere to hunt from, so they get stranded in the water and drown. Many also starve while stuck on an iceberg where there is nothing to eat nearby. Most scientists agree that the major cause of climate change is the burning of fossil fuels, so help save the polar bears by conserving resources. Learn some fascinating facts and observe the lives of these arctic hunters on NGC's Polar Bear Invasion.
