There was a time when you'd return bottles to the manufacturer and they were seen as responsible for what they chose to manufacture.
Somewhere down the line, all of this, 100% of it was placed on the end user - as if the billion dollar company with tens of thousands of employees and control of an international supply chain has no agency whatsoever to make any decisions at all and they exist as mere errand boys of the supposedly all powerful consumer.
None of these things will be fixable until we collectively stop fantasizing that someone paying $1 for a soda has more power in the fundamental decisions of how it's manufactured than the company's board of directors.
