I don't know about others, for me it's difficult to get away from plastic, my refrigerator is plastic, the freezers plastic, the vehicle is plastic, in the grocery store a lot of items are in plastic, everywhere I turn some form of plastic is there, glaring.
I have some stainless steel items, I can say it has a shelf life too, also save glass containers that are reusable for personal use. I thinks it's more about doing the best one can do with means to do it until it an upgrade is possible.
