In his new book, Crossings: How Road Ecology Is Shaping The Future of Our Planet, independent conservation journalist Ben Goldfarb writes about how roads and cars are wreaking havoc on nature across the globe.

Plus, he helps us analyze a couple of egregious ads that show how humans use roads to assert our dominion over the natural world…to our own eventual detriment. {listen}
