Answer 1

Here are four clear benefits (2 environmental, 2 economic):

Environmental benefits
1. Reduces stormwater runoff — The plants and soil soak up rain, so less water flows off the roof into storm drains and local rivers.
2. Lowers heat and improves air — Green roofs cool the building and nearby air (reducing the “urban heat island”) and plants help clean the air by trapping dust and absorbing some pollutants.

Economic benefits
3. Saves energy money — The plants and soil act as extra insulation, so the building needs less heating in winter and less air conditioning in summer, lowering energy bills.
4. Cuts maintenance and replacement costs — A green roof protects the roofing materials from sun and weather, so the roof lasts longer and needs fewer repairs.
