billboard features over the years, from facial recognition to interactive Pong games, but few have managed the dual feat of promoting a popular soft drink and making the world a slightly greener place. All of that fuzzy area you see surrounding the silhouette of the Coke bottle in the above 60 by 60 foot billboard is made up of a number of Fukien tea plants, each of which can soak up around 13 pounds of carbon dioxide per year, for a combined total of 46,800 pounds. The plants are housed in pots made from recycled Coke bottles and are watered via a drip irrigation system. The billboard is the product of a partnership between Coca-Cola Philippines and the World Wildlife Fund. No word on when it might be greening up more skylines around the world. Press release below.
