I think expecting each person to trace the incredibly complex chains of businesses and processes that result in every product they buy is unrealistic. Sure, some stuff is obvious, but plenty is not.

It reminds of of an episode of the Good Place where an angel buys a tomato at the supermarket and inadvertently commits like 14 sins due to the deep chains of unethical practices that brought the tomatoes to the store - which of course no one could possibly know when they picked it up.

IMO corporations aren't going to self-regulate and consumers arent going to do 2 hours of research on everything the buy - it's supposed to be the governments job to spend the time identifying pollution sources and regulating them away - but with regulatory capture and corruption that doesn't usually happen either.
