You know that

An ad campaign for Greenpeace encourages homeowners to paint their roofs white. White roofs help to reflect the sun’s rays, cool down the environment, and curb global warming—as “one degree cooler in our cities equates to three degrees at the poles”. This helps to preserve arctic animals and their homes. 

‘White is the new green’ ads are created by Ogilvy & Mather (Johannesburg, South Africa), which features white roofs combined in a community, to make up: an arctic hare, arctic fox and polar bear.
