An awful lot of pre-packaged meals designed to be heated in the microwave come in (and sometimes, be eaten from) plastic trays. They couldn't really come another way. You can say people shouldn't use those but if that is their lifestyle beacause they don't have time to prepare meals then you lost the "insanely easy" argument.

Just put the frozen stuff into a bowl or plate and microwave it. That's what I used to do and it's insanely easy.

> 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.
