Question

A green roof is created by adding soil and plants to a specially designed roof. Scientific research has shown that a green roof has many benefits compared with traditional roofs. Plants naturally absorb energy from the Sun and convert it into chemical energy that is stored in the bonds of sugars during photosynthesis. The soil materials also help insulate the building. In addition, a green roof helps control runoff as plant roots absorb rainwater. If local plants are used in the green roof, it may provide habitat for native species.
