On display near San Francisco’s Golden Gate Bridge in Crissy Field, the sculpture created by artists Joel Deal Stockdill and Yustina Salnikova is made up of plastic from discarded water bottles, bags and lids.

The work is a collaboration of the Monterey Bay Aquarium the National Park Service and the Golden Gate National Parks Conservancy.
