New modelling study shows that most plastic debris on Seychelles beaches comes from far-off sources The Seychelles and other islands in the western Indian Ocean are not to blame for the majority of the plastic debris that builds up on their beaches, according to a recent modelling study. The main countries contributing to land-based plastic debris were determined to be Indonesia, India, and Sri Lanka. For more detail reach us at online assignment service Dunedin. The Seychelles also gather a lot of marine-derived plastic trash from fisheries and shipping channels. The findings demonstrate the urgent need for a binding global plastics treaty and stronger regional plastic waste reduction regulations. A high-resolution model simulating the spread of plastic waste throughout the oceans was created for a recent study led by the University of Oxford to investigate this. This forecasted the buildup of plastic debris at 27 locations in the Seychelles and the larger western Indian ocean using input data on ocean currents, waves, and winds as well as plastic trash entering the ocean via coastal populations, rivers, and fisheries. In Marine Pollution Bulletin, the findings have been reported.
