This is the smallest island, but it's growing very quickly.
New stuff washes up on the shores constantly and adds itself to the land.
I noticed that the inside was covered with barnacles. They'll grow on anything you stick in the water, whether you like it or not. It's not an earth-shattering discovery, I suppose, but it makes me feel less obliged to clean up after the beach. Of course, I don't throw plastic cups into the ocean. But everything on the island was somehow created from stuff that washed up on the shores.
