I recommend listening to the audio and then watching Dr. Ruzo's full TED Talk, given in 2014 in Rio de Janeiro. His story begins with curiosity, legend, and history. It provides insight into indigenous knowledge, geothermal science, ecology, and the concept of ecotourism.
It even touches on coffee! And from the TED Radio summary, I learn of Dr. Ruzo's coffee connection. In addition to growing up in Peru, part of his childhood was near volcanoes in Nicaragua, which means he is not far removed from coffeelands.
