Marine Litter

Vital Graphics


Despite knowledge of the role played by rivers, there are

no global estimates of the amount of man-made debris

reaching the ocean at river mouths. Therefore, of the

estimated 4.8 to 12.7 million tonnes of litter which enter

the marine environment in 2010 from land-based sources

within a 50 km-wide coastal zone (Jambeck et al., 2015),

the proportion delivered by rivers is unknown. Debris

originating more than 50 km inland from the coast would

also need to be added to the figures above. The quantity

and composition of anthropogenic debris delivered by a
