In the single week that world leaders convened for high-level UN talks in New York, nearly 100,000 water bottles' worth of microplastics swirled through the city's air, posing known and still unknown risks to human health. "We want to stop the plastic waste. This is a solvable problem," Anne Beathe Tvinnereim, the Norwegian international development minister who is helping lead the charge to seal a global plastics treaty in South Korea later this year, tells AFP. The treaty aims to marshal an international response to the plastic trash that is choking the environment, from oceans and rivers to mountains and sea ice, moving up food webs as it is ingested by animals.
