Live in a hobbit home and saving our planet too

Only a few days ago I saw Al Gore's an inconvenient truth. I'm sure that lots off you people have seen this movie too. (If not please see it) It's almost impossible not too think about ways to reduce CO2, after seeing this movie. And then one morning I saw these pictures off a "hobbit home". It was so inspiring to read about this family designing and building there own home.

Simon Dale on his site,"The house was built with maximum regard for the environment and by reciprocation gives us a unique opportunity to live close to nature. Being your own (have a go) architect is a lot of fun and allows you to create and enjoy something which is part of yourself and the land rather than, at worst, a mass produced box designed for maximum profit and convenience of the construction industry. Building from natural materials does away with producers profits and the cocktail of carcinogenic poisons that fill most modern buildings."
