When you eat or drink things stored in plastic, wear plastic, sit on plastic, taste it, smell it, and so on, plastic is incorporated into you.
There is a bi-directional communication between plastic and things that contact it, meaning that plastic gets into the food, and food gets into the plastic, as well as you.
So, when you eat the things that plastic contacts, quite literally, it becomes you. In other words, you are what you eat. . . drink. . . and breathe. . . plastic!
What’s so bad about having plastic in you and on you?
Two things make it hazardous.
First, plastic is made by combining many toxic synthetic man-made chemicals by a process called polymerization. The plastics industry tells us that this process binds the toxic chemicals together so tightly that they are no longer toxic to us. But they don’t tell us that the polymerization process is never 100% perfect. It always leaves some of those toxic chemicals available to migrate out of the plastic product and into whatever contacts it—your food, you, air, water, and so on.
Secondly, many of these chemicals not only cause cancer, but also disrupt the normal functioning of the endocrine system of most animals, including humans. They have been given the name endocrine disruptors. These toxic man-made chemicals have been shown to be accumulating in the bodies of both humans and the animals we eat.
Hormones act in single digit part/per/trillion (PPT) concentrations, and have an effect on virtually every bodily function. The effects of disrupting the normal activities of hormones can be devastating and permanent. The industry answer to the warnings of environmentalists is that the toxic chemicals that make up plastics do not come out.
Once understand that you are aware of the fact that those toxicants always migrate from all plastics, then they change their tune and say that it happens at extremely low levels that cause no harm, and that the migration happens well below the regulatory limits. On that point they are mostly right, but they wrote the regulations and eased them into law through political contributions.
There is more detail on this below, but understand that there are no regulations that protect anyone or thing from the PPT concentrations that do get into our food, water, air, and bodies. One thing to remember when reading this is that a great deal of the harm caused by plastics cannot be repaired. The damage is permanent.
