Plastic from water bottles contains about two orders of magnitude more micro plastics than regular tap water. So yes, personal action can have an effect and the size of that effect is about 100x. It’s not possible to keep micro plastics out of your body 100%, but like everything it’s a question of how much. Even your tap water contains compounds like cyanide in trace amounts that we can measure, but that just says more about our ability to measure Tony quantities of compounds. You have to look at the relative significance of different amounts.
