Jane Goodall
Iconic images of Jane Goodall with her chimpanzee friends illustrate her passion for these endangered species. From age 26, she has spent time studying chimps, helping humans to understand these complex primates.
This British primatologist does not only champion a chimpanzee cause, but she also works towards bettering the communities around the chimps. Her nonprofit organization, The Jane Goodall Institute, engages people worldwide in efforts to care for our planet.
