Green Roofs
It's a simple concept- put grass/plants on a roof and reduce toxic rainwater runoff
which pollutes our drinking water. Nature has shown us the way, plants drink and purify
water for us, so let them do their job. Green roofs also provide massive energy
efficiency
by cooling a building/house in the summer and keeping them warm in the winter.
