San Antonio Spurs forward Harrison Barnes is partnering with UNICEF for International Day of Play. The Play Can't Wait campaign emphasizes the importance of play in children's lives and development. Barnes remembers the feeling of being a kid and shooting hoops at the court outside near his home. It was his escape, his sanctuary. Now, he wants to ensure other children have the same access to play. With International Day of Play on Thursday, Barnes and UNICEF are urging kids to get outside and play. Play is a fundamental part of childhood, which helps kids develop problem-solving skills, creativity and emotional resilience. For children living through crisis, it offers an outlet of stability, routine and normalcy. The UNICEF campaign advocates for the millions of children across the globe without safe places or resources to play. As part of the campaign, UNICEF is raising money to send resources like books, games, jump ropes and soccer balls to kids around the world. Barnes believes all kids have the right to dream, to learn, to play. The chance to play has given him all three and the resilience to keep going when things get hard. For children in crisis, this is a lifeline.
