So, one of the books Ethan got me for my birthday last September is Gaia's Garden, which is all about permaculture -- the idea of building organic gardens that are basically self-sustainable. I've been reading it in preparation for when (when!) we buy our own house, and it's pretty cool.
While surfing on the internet, I found this video about a permaculture project near the Dead Sea. This is an area which is basically void of life and considered to be very difficult to farm. This man built a farm using some of the ideas of permaculture and was able to create an organic farm that is thriving in a very harsh environment.
Check it out. Even if you aren't really into gardening, it's pretty cool.
