Only if we understand can we care. Only if we care will we help.

Jane Goodall

In 1960, primatologist Jane Goodall went into the Tanzanian jungle to observe the chimpanzee community in Gombe Stream National Park. Day after day she sat quietly among the animals, and eventually she observed the chimpanzees using tools, a discovery that changed the way we think about primates. After reading her findings, her mentor, paleoanthropologist Louis Leakey, famously said, "We must now redefine tool, redefine man, or accept chimpanzees as human." The more Goodall learned about the chimpanzees, the more concerned she became for their survival. In 1997, she established the Jane Goodall Institute and began educating people about other primates. Now in her 80s, she travels 300 days a year speaking on behalf of chimpanzees and working tirelessly to help preserve their populations.
