It is estimated that 80% of marine waste comes from land. This pollution comes mainly from household waste, which is poorly collected, poorly recycled or abandoned in the wild or on the roadside. This waste will be carried by the winds, pushed by the rains to take the path of sewers, rivers and streams, and then end up in the oceans. Negligence is the main cause of this pollution, to which must be added natural disasters such as floods and tsunamis.
