Architect Bjarke Ingels proposes to turn the traditional zoo model on its head, allowing animals freedom to roam while humans remain below ground, obscured by the natural landscape, or encased in mirrored pods.
Visitors will be able to observe lions from a bunker buried beneath a hill and peep at pandas through a bamboo screen. They will look at bears from a little house hidden in a stack of tree-trunks, and gawp at giraffes through holes cut into a hillside.
