Plastic pollution litters our seas, our air and even our bodies, but negotiators face an uphill battle next week to agree on the world's first treaty aimed at ending the problem.

More than 90 percent of plastic is not recycled, with over 20 million tonnes leaking into the environment, often after just a few minutes of use. Microplastics have been found in the deepest parts of the ocean, the world’s highest mountain peaks and just about every part of the human body.

Plastic also accounts for around three percent of global emissions, mostly linked to its production from fossil fuels.
