Clean-up devices that collect waste from the ocean surface won’t solve the plastic pollution problem, according to a new study. Researchers compared estimates of current and future plastic waste with the ability of floating clean-up devices to collect it – and found the impact of such devices was “very modest.”
However, river barriers could be more effective and – though they have no impact on plastic already in the oceans – they could reduce pollution “significantly” if used in tandem with surface clean-up technology.
