#humankindbysalma, in honor of Earth Day. Dear Wangari, thank you for inspiring me to believe that each one of us can do something—the best we can—to make the world a better place; for showing me what it means to live with dignity, work with conviction, and never give up, no matter the odds; for teaching me that we can live gently but be fiercely committed to what is just; and, for sharing with me just how warm a hug can feel and how wide a smile can stretch.
