The 11th Hour August 31, 2007 : 11:28 PM

As you know, the Earth is moving closer to several negative "tipping points" that could -- within as little as 10 years -- make it virtually impossible for us to avoid irretrievable damage to the planet's habitability for human civilization. That is one of the reasons why it is urgent we take action as soon as possible.

My friend Leonardo DiCaprio has just produced an amazing documentary on this subject. The film was created using over 150 hours of interviews with some of the brightest minds on the planet, including physicist Stephen Hawking and Nobel Prize winner Wangari Maathai. Moreover, Leo himself is very eloquent and persuasive in this movie. I recommend it highly.

Through interviews and beautiful footage of the environment, The 11th Hour demonstrates how human beings have created the climate crisis and related environmental crises, and shows that we have the means to solve them.

The 11th Hour is both a portrait of a planet and a source of hope and solutions.

I hope that you will go to see this important film. You can find out if The 11th Hour is playing near you by visiting
