Every three days on this site I see a "penises are shrinking due to microplastics" post. Before you call the volcel police on me, there are myriad other health reasons to avoid microplastics. So what can a normal person without much money do to reduce avoid microplastics?
Store your food in glass or wax, especially for extended periods. Plastic chemicals will leech out of bottles and containers over time. It’s really the chemicals that will come off the plastics than anything else I think, it’s just the micro plastics have more surface area.
Same goes for clothing, avoid plastic fabrics as little bits will come off in the wash and also on your person.
Otherwise there’s not really a good way to avoid it individually.
