Billboards get a bad rap, and rightfully so. The vast majority of them just sully the visual environment. But a new billboard in the Philippines might actually make the world a little better, in its own small way, by reducing air pollution.
Coca-Cola teamed up with the World Wide Fund for Nature (the local name for the WWF) to build this 60-by-60 foot plant billboard in Makati city. According to a release from WWF-Philippines, the 3,600 potted Fukien tea plants can absorb as much as 46,800 pounds of carbon dioxide over the course of a year.
The ad is also made out of recycled materials. Each of the plants is potted in discarded bottles from Coca-Cola company products. They are specially modified to allow the plants to grow sideways with an efficient drip irrigation watering system.
