This is Caroline. Beautiful smile, right? She's smiling because she's drinking clean water for the first time. She used to walk three hours every day to fetch dirty water. But not anymore. Her village just got a well. Clean water will change everything for Caroline and her community. For every Caroline, there are millions more children hoping to smile like that. Almost a billion people on the planet don't have clean water right now. Who knows how many people you will impact. This is where it begins. Start a campaign, create a group, invite your friends. Give up your birthday, climb a mountain and run a marathon. And smile. Because what you do here changes lives.
