#Microplastic #pollution found in insect casing from 1971! https://www.nature.com/articles/d41586-025-01265-y

Caddisfly larvae incorporated #microplastic particles into their protective casings as early as the 1970s. This discovery, made through the examination of museum specimens, indicates that #microplastics were present in rural freshwater streams long before they became a focus of scientific study. (1/3)
