I enjoy Geoff's videos and appreciate all the work he's doing, but the fact that he's selling those DVDs is a bit problematic. He says he wants to change the world, he wants to help people move from mindless consumption to a more meaningful and sustainable lifestyle. And then he goes on and charges money for his videos. If he's serious about changing the world why wouldn't he want to reach as many people as possible by making the videos a free download? A decent hd camera, some editing software and a pc is all he uses, this stuff is really inexpensive these days. You can host them for free on youtube and other websites, and make money on ads placed next to the video. I know he has a youtube channel but you can only view samples there.
Also physical DVDs require a significant amount of resources to produce and ship, making the stuff available on the net would surely be much better for the environment!
