To humans, roads are so ubiquitous, they are almost invisible. They crisscross every continent and allow for travel, exploration and connection. But to wildlife, roads are dangerous divisions of habitat. Around a million animals are killed by cars every day. Roads change migration patterns, cut off animals from their food sources and create noise so loud that it drowns out the ability for some animals to communicate with each other or hunt their prey. But road ecologists are working on solutions. In his new book, “Crossings,” Science Journalist Ben Goldfarb lays out the repercussion of roads and invites us to rethink their design. For example, California is planning to build a literal animal crossing over Highway 101, to allow safe passage for a variety of creatures. Goldfarb joined host Kerri Miller on this week’s Big Books and Bold Ideas to share what he learned when he started to research road ecology and how scientists are using innovative solutions to minimize the damage roads cause. Guest: Ben Goldfarb is an environmental journalist and author. His latest book is “Crossings: How Road Ecology is Shaping the Future of Our Planet.” Subscribe to the MPR News with Kerri Miller podcast on Apple Podcasts, Google Podcasts, RSS or anywhere you get your podcasts.
