A sea turtle named Herman, an octopus called Octavia, and a seal named Lidia all spent this summer at the Smithsonian’ s National Zoo in Washington, D.C. But unlike the zoo’s other residents, they are not real animals. These creatures are actually huge sculptures and they’re made entirely out of plastic trash from the ocean.

These giant artworks, along with 14 others, are part of a traveling exhibit called “Washed Ashore: Art to Save the Sea”. The Washed Ashore project, led by artist Angela Haseltine Pozzi, works to raise awareness about the problem of plastic pollution in Earth’s oceans.

More than 315 billion pounds of plastic litter the world’s oceans today. Most of the plastic is garbage from towns and cities, as well as trash that people leave on beaches. rainwater, winds, and high tides bring the trash into the ocean or into rivers that lead to the ocean. Once it is under the waves, the plastic begins to break up into smaller and smaller pieces. It often collects in spots called garbage patches, which spread over large areas of the ocean.

Thousands of marine animals--including whales, sea turtles, and fish--die each year from eating or getting stuck in plastic bags and other items. Plastic pieces can also injure coral and kill sea grass.

Washed Ashore and other organizations are working to stop that from happening. Since 2010, Washed Ashore volunteers have collected 38,000 pounds of plastic trash from more than 3000 miles of beaches. They helped Pozzi create more than 60 sculptures of marine creatures that were harmed by plastic pollution.

The artworks on display at the National Zoo include a 20-foot-long coral reef, a 12-foot-long shark, and a 16-foot-long parrot fish. Each one is made from hundreds of pieces of trash like water bottles and sunglasses.

“These sculptures are a powerful reminder of our personal role and global responsibility in preserving biodiversity(生物多样性) on land and in the sea,” says Dennis Kelly, director of the National Zoo.
