How are tiny plastic particles darkening Himalayan white glaciers?

A comprehensive meta-analysis of 562 studies, led by researchers from the Govind Ballabh Pant National Institute of Himalayan Environment, reveals that microplastics have extensively contaminated the #HinduKush Himalaya. They are turning melting glaciers into active sources of pollution. This contaminates the water supply of nearly two billion people across the ten mega-river basins.
