Traveling from Ecuador to Africa, Jane Goodall takes the audience on an ecological journey, discussing highlights and low points of her experiences in the jungle. She shows how progress is helping research (DNA analysis) and hurting the environment (clear-cutting). And she draws a dozen parallels between primate and human behavior, making the point that we really aren’t all that different. Our big advantage, she says, is the ability to communicate with sophisticated spoken language — yet, sadly, we are abusing this power and destroying the planet. She urges the TED audience to behave differently, and use their higher powers to correct the planet’s course.
