The climate crisis threatens to destroy our entire cultural & ecological heritage in a matter of decades – how can we document everything before it disappears? In this fascinating talk, archaeologist Chris Fisher will take you deep in the Honduran jungle on an expedition to find a lost city and explain why we must LiDAR scan the entire surface of the Earth, not just as a record for future generations, but as a tool to fight climate change and save our planet. Dr. Chris Fisher is an archaeologist, National Geographic Explorer, Professor of Anthropology at Colorado State University, and the Founder & Director of The Earth Archive. In 2007, he and his team first documented the ancient city of Angamuco, a sprawling metropolis that once had as many structures as modern-day Manhattan. His recent work uses remote sensing technologies, including LiDAR, to better understand urbanism & environmental change in Mexico and Honduras. As a child growing up in Duluth, Minnesota, he developed a love for wilderness canoeing, a passion that persists today. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx
