Celebrities have a lot of power because of the adulation which they attract . This is why they act as brand ambassadors to lead social campaigns, since their actions catch the public imagination.
Lots of people are quite cynical about some of these celebrity endorsements. They believe these "go-good" activities are used by them as vehicles to improve their public profile and popularity. Every once in a while however, you come across a celebrity who uses not just his face and his goodwill, but also his brains to be able to do something to make the world a better place.
