This book turned me on to the subtleties and importance of dirt: Dirt: The Ecstatic Skin of the Earth. And now there's a movie that does the same: Dirt! the Movie.
As even the preview below asserts, dirt is one of the most important factors to life on earth. It doesn't get more fundamental than that. This is why our house buys organic products. It's not only because there are health benefits for us, but more importantly it directly pays farmers to take care of the soil. If you don't pay people to do something, how can you expect them to do it?
Check out the trailer, it looks awesome.
Enjoy learning more about the systems that directly sustain you,
