The best way to avoid microplastics—and to curb our contribution to microplastic pollution—is to use less plastic. “You don’t need to get rid of all your plastic and buy new things,” says Penn State’s Sherri Mason. “But as things break or you lose them, try to replace them with reusable items made out of more sustainable materials like glass or stainless steel.” And curbing plastic doesn’t have to mean spending money. Wash out and reuse food jars. And repurpose tote bags into grocery or produce bags (or sew your own!). Here are some other tips to get you started.
