Global simulations of marine plastic transport show plastic trapping in coastal zones
Environmental Research Letters, 2021 Abstract Global coastlines potentially contain significant amounts of plastic debris, with harmful implications for marine and coastal ecosystems, fisheries and tourism. However, the global amount, distribution and origin of plastic debris on beaches and in coastal waters is currently unknown.
