Biodegradable plastic does not work and ocean cleanups can only do so much – 30 years after his discovery on a beach led to a new field of research, Richard Thompson has plenty to say on a growing global problem
In September 1993, during a beach clean on the Isle of Man, Richard Thompson noticed thousands of multicoloured fragments at his feet, looking like sand. While his colleagues filled sacks with crisp packets, fishing rope, plastic bags and bottles, Thompson became transfixed by the particles.
They were so tiny that they did not fit any category in the spreadsheet where volunteers recorded their findings. “Yet it was pretty clear to me that the most abundant item on the beach was the smallest stuff,” Thompson says.
