How seeds shaped the world; then gas drilling and water contamination

Listen 00:48:43

Guest: Thor Hanson

Springtime means many of us are planting seeds in our gardens – sprinkling them into the warming soil and waiting for them to grow and transform into vegetables, flowers, or trees. Seeds are essential to our lives, from the food we eat to the clothing we wear. Conservation biologist THOR HANSON celebrates the seed and it’s influence on natural world and human civilization in his new book, The Triumph of Seeds: How Grains, Nuts, Kernels, Pulses, & Pips Conquered the Plant Kingdom and Shaped Human History. Then, hydrologist GARTH LLEWELLYN, author of a new study linking natural gas drilling to water contamination in Bradford County, PA
