While we don't know exactly how much trash is afloat in the ocean, one thing is sure: there's a lot of it. One expedition found up to a ton of garbage per mile on remote beaches in Alaska. Campers learn about recycling and sustainability and how artists have used trash to make both beautiful art and functional objects. On museum visits, they see furniture fashioned from recycled game pieces, portraits made from old cassette tapes, and a coral reef made from trash found on the beach. These provide the inspiration for their own trash-to-treasure ocean creations, unveiled for guests at a Friday showing.
