"Every single one of us has a role to play, and every single one of us can make a difference." On what would have been Dr. Jane Goodall's 92nd birthday, we celebrate her enduring legacy. Her groundbreaking research on chimpanzees at Gombe Stream National Park in Tanzania challenged the conventional scientific beliefs of her time and helped bridge the gap between humans and the rest of the animal kingdom. That research — now the longest-running wild chimpanzee study in the world — continues today through the JaneGoodallInst. As we celebrate the first annual #JaneGoodallDay, we are reminded of Jane's message of hope: "What you do makes a difference, and you have to decide what kind of difference you want to make."
