The Story of Stuff
Not sure if you have checked out the Story of Stuff videos yet, but I am thrilled with them. Accessible, compelling without being militant, and very well done. Here's a teaser.
What I am finding in my eco evangelism is that many people understand the need for recycling, energy efficiency, and habitat preservation. But they often do so in a piecemeal form, and lack the knowledge of how it all ties together to be able to Root Cause some solutions. The Natural Step and Permaculture are great ways to provide solutions, but many people are no where near ready for that level of detail yet.
I am more of a "do-er" than a marketer. I prefer to work on the solutions and let others work on marketing. And that is why I love videos like this, books like Omnivore's Dilemma, and movies like an Inconvenient Truth. They are laying a foundational awareness so that a critical mass of the population can be ready for change before it is too late.
