In a centuries-old tradition, farmers in north-western Iceland scour remote coastal plains for the down of nesting eider ducks. High inside a cast cave in Borneo, men perched on rickety ladders collect swiftlets' nests, a delicacy believed to be a cure for almost anything. These luxury products are two of the seven natural wonders whose stories this book tells.
