In more ways than we know, our lives are built on trash. If you stacked up all the world’s old junkyard tires, they would reach to the moon and back. So what can we do with them all? How about building houses.

 Invented by architect Michael Reynolds of Taos, New Mexico, Earthships are custom-built, off-the-grid houses built from recycled materials, like recycled bottles (pictured), aluminum cans, used tires, pieces of cardboard – even old fridge doors.
