A Healthier Planet

 

Intensive roof gardens can add to the local economy by producing food that provides greater nutritional value to the community because it's accessible immediately from the garden, without travel time. In addition, the visual benefit of adding greenery, particularly to the urban landscape, has been shown to reduce stress and to have therapeutic health benefits, which accelerates recovery from illness. Rooftop gardens also increase habitat opportunities for birds, bees, and other insects.

 

Green roofs are a great example of how creating more sustainable ways of doing things can benefit the planet, its people, and even their pocketbooks.
