I was just watching CNNs show Planet in Peril and wow is it powerful. Yes I know it is sensationalized, but some images are very powerful on their own... Regardless, it's super entertaining and makes you think... I wish I had someone to give it to for Christmas, they have it on DVD which would be perfect for people like me, who can't seem to make it home regularly enough to watch a show consistently. If you are more organized than I am its on CNN at 8pm on Saturday and Sunday nights you can also check it out some clips here or buy/download the DVD!
