The human body is a metaphor for the natural world and the natural world is a metaphor for the human body, the Nigerian artist Otobong Nkanga seems to say. Her tapestries, drawings, videos, and sculpture materialize the connections between Earth’s geography and our own. Wounded bodies—fragmented, sometimes headless—symbolize environmental degradation. Damage to one means damage to all. Nkanga’s layered message is wondrously omniscient, as if delivering an urgent message from the beyond. —Clara Molot
