Jane Goodall
(2 of 2)
When I was doing the research for this book, I met so many extraordinary people who rescued species from the brink of extinction when everybody else laughed at them. One example is the California condor. At one time, there were just 12 of these birds left in the wild and one in captivity. Now there are 300. This bird would have gone but for a small group of people who would not give up. As long as we have people like that, there's hope for the future.
