>That's my entire point. We don't.

Yes, we do.

knock yourself out I'd say, plenty of research on this subject.

I'll provide you with a single excerpt, again you're free to dive deeper into this.

>Plastic contains chemical additives, most of which remain unknown or understudied. Meanwhile, many of the chemicals additives for which scientific information is available are known to be toxic. A growing body of evidence points to the health risks posed by plastic additives. These include endocrine disrupting chemicals (EDCs), which are linked to infertility, obesity, diabetes, prostate or breast cancer, among others. Other health conditions linked to additives include reproductive, growth, and cognitive impairment and neurodevelopment disorders.

there's plenty of research that needs to be done still in this field if we want an accurate picture, but what we know already is pretty damning.

And that is only the health aspect of it. Like I said in my previous comment, most plastics aren't recyclable, so that's 50 kilo per person per year that gets tossed somewhere, anywhere, you're free to do the math on how much avoidable waste that is globally.

On that note, show me a fish, and I'll show you plastic.
