Thousands of delegates have descended upon Geneva this week for what’s supposed to be the culmination of years of negotiations that, if successful, are supposed to end in a groundbreaking global plastics treaty. That’s why health and environmental advocates, as well as a coalition of governments, are pushing for an ambitious plastics treaty in Geneva. Negotiations on a plastics treaty in Geneva are scheduled to end on August 14th. The Lancet article similarly says “the principal driver of this [health] crisis is accelerating growth in plastic production.” Production has ballooned from 2 metric megatons in 1950 to 475 in 2022. “I hope and I pray that the treaty negotiators are actually going to produce a treaty that protects human health.”
