I moved about 6 months ago and don't have tv, but have Netflix. I've been watching a lot of documentaries since then and I must say this is one of the best... really makes you want to cry because we've done it to ourselves. That's why polar bears are now an endangered species.
If anyone is interested in watching you can get a 30 day free trial at netflix. You can also see the website at Extreme Ice Survey | Art meets science.
