Representatives from 170 countries are gathering in Geneva, Switzerland, today in the hopes of finalising a global treaty limiting plastic pollution.

December talks in South Korea collapsed after a small number of fossil fuel producing nations blocked attempts by 100 countries to introduce a legally binding treaty that limits plastics production.

Ahead of this week's summit, health experts have urged the United Nations to take a stronger stance against plastic pollution, which they describe as a "grave, growing and under-recognised danger to human health".
