Carnegie Mellon's 'greenscape'
Carnegie Mellon University built a "greenscape," which collects rain water to nourish a series of plants on the front of the house.
The house also features an artistic installation in the back that uses plants to represent how the environment can change from global warming, depending on which path the planet takes.
