Walking through SCMA’s newest exhibit, I couldn’t get the chorus of The Who’s “Baba O’Riley” out of my head: “Don’t cry / don’t raise your eye / it’s only teenage wasteland.” The song’s otherworldly warning seems to be woven throughout the artwork in “Plastic Entanglements: Ecology, Aesthetics, Materials,” an exhibit that documents the past, present and future of plastics and human existence. The 20th century got to enjoy the thrilling innovations of plastic, inadvertently creating an archive of the costly convenience of daily life. Now, the upcoming waves of youth will inherit what is left of this material’s legacy: an impending wasteland. “Entanglements” confronts the viewer with the medium’s metamorphosis, asking whether the possibilities of plastic can ever make up for the destruction it wreaks.
