Peter Raven is St. Louis' own Hero of the Planet. Since 1990 he's been a Senior Science Advisor to the Pontifical Academy of Science, most recently one of the minds behind the letter from Pope Francis, released on June 18, framing climate change as a moral issue for all people of this Earth.
Dr. Raven, who is President Emeritus of the Missouri Botanical Garden, talks with Earthworms host Jean Ponzi about the papal message, about this moment for humankind, and about the potential each one of us has to make the changes needed to heal and protect the Earth.
Read the climate change encyclical, Laudato Si' - and be assured that our individual efforts do matter in a world where "climate is a common good" and ". . . .nothing is indifferent to us."
Thanks to Earthworms engineer, Andy Coco.
