You can see a sea turtle named Herman, an octopus ( 章鱼) called Octavia, and a seal named Lidia at the Smithsonian’s National Zoo in Washington, D.C. Rather than real animals, they are actually artworks made out of plastic trash from the ocean.

These artworks are part of a traveling exhibit called “Washed Ashore: Art to Save the Sea”. The Washed Ashore project, led by the artist called Pozzi, works to raise awareness about 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.

Thousands of sea animals die each year from eating plastic bags and other things. Each year, millions more pounds of plastic end up in the ocean. A recent study found that if that continues, by 2050 the total weight of plastic will be more than that of all the fish in the ocean.

The Washed Ashore project is working to stop that from happening. Since 2010, Washed Ashore volunteers have collected 38,000 pounds of plastic trash from more than 300 miles of beaches. They helped Pozzi create more than 60 artworks of sea creatures harmed by plastic pollution.

“These artworks 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.
