Modern day North America is far removed from the continent first encountered by people 13,000 years ago. Today it is dominated by symbols of human culture; then it was dominated by mammoths and sabre-toothed cats. This final programme examines the evidence for the cause of the Ice Age extinctions and takes a journey through time to see how the survivors have adapted to the altered landscape of North America. From mammoth hunting through to the rise of the skyscraper we see how wildlife has adapted to a human-controlled New World.

Built for the needs of people, cities have also become home to all manner of North American wildlife. Moose roam through downtown Anchorage during the winter, eating people's garden plants and destroying Christmas tree lights. Manatees gather in their hundreds to bathe in the warm water pumped out by a Florida power plant, and burrowing owls raise their chicks in one of America's biggest urban sprawls - Silicon Valley.
