The personal responsibility theory of pollution was made up by these corporations you are defending. The reason that companies make products is to sell them yes. But the reason the products are made in polluting ways and with essentially unrecylable materials is cost cutting. Regulate industries to use the more expensive but less impactful production methods, and you find that pollution will actually go down in a way that matters. Tell individuals to stop buying plastic bottles and you'll get a subset of the middle to upper class to somewhat comply. Make plastic bottles illegal (or at least mandate that the company buy them back to really recycle) and the problem becomes moot, it's not like individuals can make plastic. Same for fuel, waste disposal, etc, etc. The only thing consumers could do is buy less, but life makes that rather hard. The companies that you are trying to absolve lobby to make that harder.
