The world is in a “plastics crisis”, it concluded, which is causing disease and death from infancy to old age and is responsible for at least $1.5tn (£1.1tn) a year in health-related damages.

The driver of the crisis is a huge acceleration of plastic production, which has increased by more than 200 times since 1950 and is set to almost triple again to more than a billion tonnes a year by 2060. While plastic has many important uses, the most rapid increase has been in the production of single-use plastics, such as drinks bottles and fast-food containers.
