「Trash House」
As the earth gets more crowded, the mountains of trash in every town and city are growing. What should we do with all this junk? Sharon and Jack Ehrhard are helping to solve the problem. Their house is made of trash. They collected most of the building materials for the house themselves―for free! The outside walls are made of about 1,000 used tires that were filled with dirt and then covered with plaster. The inside walls consist of old cans and glass bottles, which are covered with a cort of dirt and mud. The thick walls make the home extremely strong. Since they move as the earth moves, the house can't be damaged in an earthquake.
The couple gets electricity from the sun. They collect rainwater for taking baths and washing clothes and dishes. The back of the house is buried under a small hill, which helps to keep it cool in the summer. The Ehrhardts are delighted with their earth-friendly home, called an "Earthship." Earthship are becoming more and more popular with people who are tired of trash.
