World Wildlife Foundation - Drive One Day Less

Reports of China's attempts at improving their air quality in time for the Beijing Olympics have been making the rounds on Internet news sites lately. You may have heard of some of the drastic measures they have been trying, which includes weather manipulation techniques like cloud seeding. Given the controversial and untested nature of those methods, I can't help but feel that their efforts are a waste of resources.

Meanwhile, the World Wildlife Foundation have not been sitting idle and their efforts, which is aimed more at changing destructive habits, may prove to be more effective. This eye-catching outdoor promotion featured a gigantic promotional balloon, which is actually inflated by the emissions from a car. The imprinted message informed passersby to "Drive one day less and look how much carbon monoxide you'll keep out of the air we breathe."
