With Earth Day falling on April 22, it felt right to gather the shows this season that are genuinely reckoning with the natural world — not as decoration, but as subject, material, and force. From Humid Traces at the Ford Foundation, which examines water and migration amid extreme weather, to Heath Wae's paintings built from foraged minerals and resins at Carvalho, these exhibitions approach ecology and environmental time from strikingly different angles. Some are urgent and political, others quietly meditative, but all of them ask something real of the viewer. Below, seven shows worth seeing before the month is out.
