Great ideas come at the strangest times. In Daniel Burstein's case, an idea emerged while looking at his local grocery store at a traffic light. Daniel realized how much space was wasted on the building's roof and developed a solution: turn it into an urban farming space. Supermarkets could cultivate produce and sell it in the store below to improve the experience of shopping for food and the community as a whole. Green roofs mean cooler stores, new jobs, fewer emissions, and local produce at a low price.
