That seemingly obvious, yet previously unproven, point, is the main takeaway from a first-of-its-kind study published Wednesday in the journal Science Advances. Researchers from a dozen universities around the world found that, for every 1 percent increase in the amount of plastic a company uses, there is an associated 1 percent increase in its contribution to global plastic litter. In other words, if Coca-Cola is producing one-tenth of the world’s plastic, the research predicts that the beverage behemoth is responsible for about a tenth of the identifiable plastic litter on beaches or in parks, rivers, and other ecosystems. That finding “shook me up a lot, I was really distraught,” said Win Cowger, a researcher at the Moore Institute for Plastic Pollution Research and the study’s lead author.
