Three sub-reefs of the Crochet Reef were on display at the Andy Warhol Museum as part of the exhibition 6 Billion Perps Held Hostage: Artists Address Global Warming.

Curated by Warhol Museum archivist Matt Wrbican, 6 Billion Perps… was one of the first major gallery shows to address the topic of global warming. Twelve artists and art collectives were invited to contribute to the show, which also included a gallery displaying Warhol’s famous Disaster paintings and his Endangered Species prints. The exhibition was timed to coincide with the centenary of the birth of Pittsburgh native Rachel Carson, author of Silent Spring, the book that launched the modern environmental movement.

The IFF exhibit, designed and curated by Margaret Wertheim and Christine Wertheim, comprised a Crochet Coral and Anemone Garden featuring a sea slug by Marianne Midelburg, kelps by Barbara Wertheim, and shell forms by Sarah Simons; plus a Branched Anemone Garden, with contributions from Shari Porter, Helen Bernasconi, Lynn Latt, and Allie Gerlach; and a Kelp Garden, with contributions from Sarah Simons and Karen Frazer.

On the exhibition opening night Margaret gave a talk about the Crochet Reef project and the devastation of marine life by global warming. In May, Christine conducted a Crochet Reef workshop to inaugurate the creation of a local Pittsburgh Reef.
