In 'Crossings,' environmental journalist Ben Goldfarb uncovers the vast and often overlooked impact of the world's 40 million miles of roadways on wildlife and ecosystems. With roads acting as deadly barriers to animal migration and conduits for pollution and invasive species, the book delves into the grim consequences of modern infrastructure. However, amid the destruction, Goldfarb discovers glimmers of hope as road ecologists concoct ingenious mitigation measures. From wildlife bridges to tunnels for amphibians, 'Crossings' presents a riveting narrative of destruction and resilience, human impact and innovation, and a call to action to balance progress with the preservation of the natural world.
