So why do you figure adding more doesn't hurt? I do a lot to minimize it. I don't eat food or drinks from plastic or styrofoam containers, including cans which are lined with plastic. I use reverse osmosis on my drinking water. I don't eat processed foods or at restaurants because I don't know where their shit came from. I don't store leftovers in plastic or use plastic utensils at home. My cookware and pans are all glass or cast iron. I don't have carpet or particle board in the house. All of our clothes are cotton or wool. Sure, I'll still breathe some stuff and whatnot, but I guarantee I have far less plastics in my system than your average bear.
