They were the first humans the chimpanzees saw. Twenty years ago, conservationist Mike FayNational Geographic photographer Nick Nichols, and writer David Quammen took on a massive more-than-3,000-mile research journey from the Republic of the Congo to the Atlantic Ocean coast in Gabon called the Megatransect. There, they encountered land so wild that the resident chimpanzees of the forest had never laid eyes on humans before. As insects swarmed around him and the rest of the team, Nichols captured on camera the very moment the chimps saw him, and the rest, as they say, is history. The team went on to create a comprehensive database of the wild lands and animals they encountered, sharing the information with Gabon’s president at the time, who was shocked to learn that all this natural beauty was there in his country. This led to the creation of 13 national parks in Gabon, and significant U.S. funding to the Congo Basin. Now, after years of being apart, the three men will come together once again to reflect on the dangerous expedition, how it changed them, how it changed conservation, and how, ultimately, it changed all of us.
