Fisheries, aquaculture, recreational activities and global wellbeing are all negatively affected by plastic pollution, with an estimated 1-5% decline in the benefit humans derive from oceans. The resulting cost in such benefits, known as marine ecosystem value, is up to $2.5tn (£1.9tn) a year, according to a study published this week in Marine Pollution Bulletin.
Plastic waste is also believed to cost up to $33,000 per ton in reduced environmental value, the study found. An estimated 8m tons of plastic pollution enter the world’s oceans every year. [Source]
