Jane Goodall, the legendary environmentalist and conservationist, has transformed how we think about ecosystems in her long career. Today, the 89-year-old primatologist is still urging people to focus on the biggest environmental crises facing us today. Her new IMAX documentary is called “Jane Goodall: Reasons for Hope.” GBH reporter Craig LeMoult sat down with Goodall at the Museum of Science in Boston, to learn about how this new film connects to her lifelong work.
