I'm concerned about microplastics too, but I think on the whole plastics have been good for health. Any harm microplastics may cause must be rather small if it hasn't been identified yet, and easily outweighed by the benefits of reducing spoilage and pathogen growth.

I somewhat agree with you. Unfortunately if it does turn out that we need to clean up the plastic pollution someday (because of longer term harms), we're pretty much fucked.
