In
other words, they live underground.
Why
would anyone want to do that?
Well,
if a house is underground, it is insulated from heat and cold by
earth and plants, and it can often stay a comfortable temperature by
passive or fuel-efficient ways, such as sunlight on a concrete-block
wall. With trees and other vegetation planted over the house, more
rainwater is conserved, more carbon dioxide is take out of the atmosphere, erosion is minimized, and of course a more natural, beautiful landscape is preserved.
A
man named Malcolm Wells built a lot of underground houses and urged
others to build some, as well. He didn't necessarily start by digging down in to
the earth. Instead, he built a strong, waterproof building (apparently
more concrete than wood), and then he covered it with earth and
planted it with native plants.
- Check out Wells's website, including some pictures of his building designs.
- Here Wells makes some suggestions for celebrating Underground America Day. Hmm...I like the idea of making a meal from things that grow underground (potatoes and carrots and peanuts come to mind), riding a subway, and designing the perfect underground house or school or shopping mall!
