Earth Hour 2013 has thousands (627 pages' worth!) of “I Will If You Will” challenges on its website for green-loving people around the globe. Miranda Kerr promises to conduct a free yoga class IF 500 people upload an IWIYW challenge. Jessica Alba will let her kids dress the Honest Company team IF 10,000 people switch to non-toxic eco-friendly products at home.
The mayor of Kuala Lumpur pledges to ride his bike to work on March 27 IF 50 buildings in Kuala Lumpur switch off their power for Earth Hour 2013. Pocoyo and his Friends will help clear the ocean of two tons of trash (with a little help from Ocean Defenders Alliance) IF 100,000 children go online and play the new Ocean Cleanup Game. And so on. It's a terrific concept and the list of challenges is fascinating.
