It's also commonly used in 3D printing, i.e. PLA. PLA is stable enough in normal circumstances -- you need specific equipment to make it degrade -- but once broken down to microplastics it doesn't last long. Otherwise it's nearly an ideal plastic for printing; brittle, but strong and incredibly easy to print. With some additives you can get rid of the brittleness, though I'm not sure how those would degrade. I see no reason you couldn't make plastic straws from PLA. Clothing might not last as long, but plastic clothing never lasts that long in any case; I prefer cotton.
