We went along the other night to the New York premiere of The 11th Hour, the Leonardo DiCaprio-produced documentary about how our climate is changing, why it is, why our politics isn't working to change it, what science and technology is doing to address it, and what we can do about it. As that last sentence indicates, the film is densely packed with very BIG issues, and it doesn't quite work. In spite of its density, it barely touches upon food issues (it does have images of factory farms and acres of wheatfields), or population, or the issue of equity and environmental justice in the developing world (which will be disproportionately affected by global climate change).

One of the problems is that the film is stuffed with talking heads—dozens of them. There's Paul Hawken, Ray Anderson, Sandra Postel, James Hillman, Mikhail Gorbachev, John Todd, Oren Lyons, and many others, including Lantern's own Wangari Maathai, who gets a couple of sentences.

Still, it's a very worthy film, on a subject that we need to be made aware of over and over again, just so we get the message and change our lives. The 11th Hour is currently in general release.
