In October, the legendary naturalist Jane Goodall died at age 91. During her life, Goodall not only saw a lot of change in the world, but made a lot of it too.

Her field work with chimpanzees transformed how both science and the general public view our fellow primates. In later years, as an activist and conservationist, she inspired countless young people to follow her lead and change the world. And despite political leaders recently seeming to prioritize the economy over the environment, Goodall always found reasons to remain hopeful.

In September, Piya Chattopadhyay spoke with Goodall about her journey and her desire to keep sparking positive change.
