The spine of the continent

the long version

As climate change encroaches, animals and plants around the globe are having their habitats pulled out from under them. At the same time, human development has made islands out of even our largest nature reserves, stranding the biodiversity other lives within them. The Spine of the Continent introduces readers to the most ambitious wildlife conservation effort ever undertaken: to create linked protected areas extending from the Yukon to Mexico, the entire length of North America. -- Jacket, p.
