Jane Goodall is an expert on alpha males — for decades, she’s been studying them in chimpanzee communities. She’s also inspired leaders in business, politics and culture to change their approach to animals and the environment.

It’s been 60 years since Dr. Goodall’s first excursion to observe primates in Africa. Her discoveries there, which transformed our understanding of animals, continue to inspire generations of scientists and environmental activists.

Now, at the age of 86, she reflects on her legacy. On this episode of “Sway,” she reveals how she rose to celebrity status, how she uses her platform to persuade world leaders and which politicians (like President Trump) she wouldn’t even bother trying to persuade.
