How Plastic Cleanup Threatens the Ocean’s Living Islands
Home to vibrantly colored, tiny creatures, the ecosystems floating on the ocean’s surface remain all but unknown.
Imagine you’re on a small boat in the middle of the open ocean, surrounded by what looks like a raft of plastic. Now flip the whole world upside down. You remain comfortably attached to your seat—the abyss towers above you, and all around, stretching up from the water’s surface, is an electric-blue meadow of life. What you thought was plastic is actually a living island. This meadow is made up of a diverse collection of animals. The most abundant are blue buttons and by-the-wind sailors, with bright-blue bodies that dot the sky like suns, and deep-purple snails found in patches so dense one scientist described collecting more than 1,000 in 20 minutes.
This is the neuston, a whole ecosystem living at the ocean’s surface. I once stumbled upon a raft of neuston when a storm blew it ashore in California. Many neustonic animals are vibrant highlighter colors, and the sand was saturated in bright blues and pale pinks. Together, these small creatures may function like upside-down coral reefs: an oasis of shelter and life far out to sea. As far back as the Cold War era, scientists were describing these colorful and important ecosystems, yet they still remain all but unknown. But now, as efforts to clean the ocean of plastic start up, our ignorance is putting this ecosystem at risk.
