Plants are nature’s natural air conditioners. A thick covering of foliage will create a cool sanctuary that can be enjoyed in the heat of summer. Trees have been used for centuries to create shade and the famous tree lined roadsides of France are said to be a legacy of Napoleon, who planted them to create a favourable environment for his marching troops. Whether this legend is true or not isn’t important, what’s important is the recognition that trees and plants play an important role in cooling surrounding environments.
