This type of habitat should also be implemented in developed countries.
Another option that might work even better in the US is straw bale adobe:

I believe the reason Kate & Co. went with Eco-Domes for Darfur was that they couldn't count on finding anything there except dirt. But there is lots of straw in the US.
What do they use for roofing on the Eco-Domes?
Ditto for mildew.
The earthquake resistance, pest resistance, and insulating qualities of straw bale construction are mind-blowing.
What other groups can you add to this list, who would be interested in building one of these for themselves?
