> Not microwaving plastic is an insanely easy lifestyle adjustment that virtually anyone can do starting immediately without effort.

I don't think anyone is arguing that it is futile to try to microwave less or to do so in ceramic or glassware - it is just not qualified if that would have any meaningful personal health impact whatsoever.

> Changing diet or exercising may be much more impactful, but they require significant time and effort - gargantuan amounts compared to just changing from plastic to glass lunch boxes.

I tend to make changes because they will be impactful, even if such changes require additional effort.
