Earth Hour 2012 - I Will If You Will

Earth Hour is almost here again. This year's theme is "I will if you will" as explained by the examples in the ad below.


Both celebrities and ordinary people are making pledges/challenges to their fan-base or their friends. See more examples on the Earth Hour's facebook.

It's amazing to think that this huge event started just 6 years ago, in one city. Official Videos: 2012, 2011, 2010, 2009, 2008, 2007
