Michael Nash has crafted a fantastic documentary using a cast of colorful and informative scientists, politicians and other experts on our changing climate, and those already being effected. I loved that the film does not take sides as to whether man is causing the change, or it's simply a natural cycle. In fact, at one point, he states that we better hope we're causing it, because that's the only way we have a chance of changing this problem. It was amazing to see the effects of a rising ocean on the island of Tuvalu, where palm trees that used to be high up on the beach are now halfway underwater. Even more amazing is that there is no plan for these people, nowhere for them to go when their island goes underwater, which will most likely happen during our lifetime. This film has caused me to get involved.
