I'm not sure if anyone has mentioned this yet, but microplastics aren't only in our fish but it's also in American tap water. There is no water filter that I know of available to the consumer public that is fine enough to filter out microplastics of under 3 microns or something like that.

As some commenters have mentioned, these microplastics come from laundry, and more.

I'm currently working on developing disposable pads that are safe with a national Toms one for one model. Current pads and tampons from major brands are made with cotton that can have dioxin as a byproduct from the bleaching process, as well as rayon. Tiny pieces of rayon can get stuck and lead to complications like BVI, bacterial vaginosis. If a tampon can lead to health issues because of the plastic that can disintegrate in her body - I'm kind of really scared about what other type of damage microplastics in our drinking water can do. I mean we already have pictures of what it does to fish. What do microplastics do to the human body?

This is one of the things where I wish I was wrong, so if anyone can educate me on how this is an irrational anxiety, I'd appreciate it!
