Welcoming Biodiversity Back To Cities

In this week’s How on Earth, we focus on how cities can foster biodiversity in an effort to mitigate the effects of climate change.

First, we speak with author and journalist Tony Hiss (4:29), who says that while the Earth is rapidly losing species, we can still do something about it. In his latest book, Rescuing the Planet: Protecting Half the Land to Heal the Earth (Vintage), Hiss recounts the numerous ways in which grassroots movements around the world are creating habitats that are allowing biodiversity to thrive, including in least obvious of places — cities.

Next, we discuss how this is being done in Colorado by the nonprofit organization, Denver Urban Gardens (DUG). Creighton Hofeditz (14:37), the Director of Permaculture and Perennials at DUG, tells us how he turns empty city lots into “food forests” — a type of agroforestry — for residents in the metro area. The creation of these gathering spaces for humans also gives nature a place to thrive.

Mankind Owes Its Success on Earth to Decimated Forests

On today’s show, Benita speaks with author John Perlin about his book, A Forest Journey: The Role of Trees in the Fate of Civilization. The book follows the rise and fall of human civilizations as they fuel their success and reap their downfall by using trees as a key resource.

Published by Patagonia, Perlin revised this third edition of his environmental classic to include new scientific findings that further link the importance of trees in combating climate change and in creating life on Earth as we know it.
