Natural Wonder: Julia Roberts
She's far more interested in philanthropy—she's on the advisory board of Gucci's Chime for Change women's initiative and is a curator for crowdfunding site Catapult. She's also a global ambassador for the U.N. Foundation's Global Alliance for Clean Cookstoves. “I had interviewed Hillary Clinton [for OWN], who has become a personal hero to me—who she is and her convictions as a woman and mother and a humanitarian,” Roberts explains. “She let me sit in on a meeting as a fly on the wall, but I'm a person who can't not say anything for too long. It's about women taking care of their families and what an incredible challenge it is for a myriad of reasons, and how fixable it can be. I saw a picture of a woman with a baby on her back, just like I would be with one of my babes on my hip, cooking at the stove. Her hut is full of toxic smoke, and that child is in tremendous peril. It's my privilege and honor to cook three meals a day for my family, and it's a luxury on a level that I didn't even realize, because it can be relentless for me on some days. You have pride in how you take care of your family.”
