This was a great movie (documentary) and well worth the money paid. It has fantastic shots of real life scenes from different parts of the world. My one fear going in was if and how it would talk about climate change. I was surprised that, although it mentioned the earth warming, it didn't talk about the cause. This I liked, as there is anything but a consensus on that and to have leaned one way or the other would have left a bad taste in my mouth. It also previewed another one that will come out in a year called "Oceans". Can't wait!
