As the earth's square footage of an urban environment keeps expanding, wild animals are increasingly making their home in these urban areas. BBC2's miniseries `Cities: Nature's New Wild' explores footage of wild animals that have made their homes in an urban environment. Narrated by David Kaluuya, a wide range of species is featured, including the smooth-coated otter in Singapore, the long-tailed macaque in Lopburi, Thailand, and the African penguin in Cape Town.
