The renowned primatologist and conservationist Jane Goodall has died at the age of 91. The Jane Goodall Institute announced her death in an Instagram post stating that her discoveries “revolutionized science, and she was a tireless advocate for the protection and restoration of our natural world.” Goodall was on a speaking tour of the U.S. and died in California of natural causes. Later in the broadcast, we’ll air excerpts of Democracy Now!’s 2015 interview with Jane Goodall.
