Groundbreaking research identifies lethal dose of plastics for seabirds, sea turtles and marine mammals: “It’s much smaller than you might think”
A recent study by Ocean Conservancy reveals that consuming as little as three sugar cubes' worth of plastics can be fatal to seabirds, while less than one-sixth of a soccer ball's worth can kill sea turtles. Marine mammals are also vulnerable, with nearly half dying from ingesting plastics, often of varying types.
