An earthship is a term used to describe a home built with materials available in one’s local area, cutting down on the fossil fuels and energy required to get the materials to the building site. The materials could be naturally occurring such as earth, stone, logs and reeds or could be discarded manmade by-products such as rubber tires, glass bottles, plastic bottles, and aluminum cans. Constructed properly, earthships construction can easily be stronger, more durable, and more energy-efficient than conventional home construction.
