Laurence C. Smith & Peter Del Tredici

March 14, 2021

Rivers have played a critical role in shaping the course of human history. Rivers provide sustenance, waterways for travel, a source of energy, have played a part in warfare, and provide political boundaries. But we also terribly abuse these resources with pollution, enormous dam projects, and diversion projects. Tonight on Inquiry we talk with  LAURENCE C. SMITH. He is the John Atwater and Diana Nelson University Professor of Environmental Studies and Professor of Earth, Environmental and Planetary Studies at Brown University. His new book is RIVERS OF POWER: HOW A NATURAL FORCE RAISED KINGDOMS, DESTROYED CIVILIZATIONS, AND SHAPES OUR WORLD.


They grow in empty lots, along railroad tracks, even in the cracks of sidewalks. They are wild urban plants, and most of us don’t give them a second glance. But they are important parts of an urban ecosystem. Tonight on Inquiry we talk with PETER DEL TREDICI. He is a botanist specializing in trees. He retired from Harvard University’s Arnold Arboretum after 35 years as a plant propagator, bonsai curator, editor of Arnoldia, Director of Living Collections, and Senior Research Scientist. He is also the author of WILD URBAN PLANTS OF THE NORTHEAST: A FIELD GUIDE.
