The uncertain future of puffin for dinner.

A wheel of wings spins around Grímsey Island, Iceland’s northernmost outpost. This eyebrow of land 40 kilometers above the mainland crosses the Arctic Circle. It’s home to some 70 residents, with one street, a tiny grocery store, a slash of airstrip roughly a third the length of the island, and a signpost pointing to the 66°33’ N parallel, across which tourists drive golf balls into the Arctic.
