Humans are literally seasoning their lungs with plastic
So we're really at the 'baking grocery bags' stage of human evolution because you wanted to save three minutes on a frozen pizza. I spend half my day sniffing actual garbage and even I know that melting dioxins into your kitchen air is a bad look. If your house smells like a tire fire and your lungs are closing up, at least you got that oven to 400 degrees slightly faster.
