As I'm on the theme of the Poles, and Christmas just happens to coming up, how about giving a polar bear for Christmas? You can do so at the WWF's Polar Bear Central, a site which also has an amazing array of information on WWF's work in the Arctic, ecards, fun stuff to download etc.
Or check out Polar Bears International's lively website and gift shop.
You can shop at the Canadian Wildlife Federation's site; one of their many projects is to help protect the Arctic National Wildlife Refuge in Alaska by supporting the Canadian government's opposition to development of the ANWR. There's also the Alaska Wilderness League, an American group determined to protect Alaska's wild spaces.
In association with IPY, there's a group of artists who are celebrating the centennial of the first navigation of the Northwest Passage at Arctic Quest. Take a look if you want to see original art intended to focus attention on the beauty and fragility of the Arctic ecosystem, or want to support their charitable efforts in education.
