Green in brief: MountainTr­ue seeks ban on single-use plastics

A study conducted by MountainTrue found an average of 19 microplastic particles — pieces smaller than 5 millimeters, formed by the breakdown of larger plastics — per liter of water in local river systems. Exposure to microplastics has been tied to allergic reactions and other health impacts in humans, as well as negative effects on fish.
