There’s some questions you have to ask about potential courses of action. Because what a company can do is restricted to what it is economically viable for them to do. Actions that are not economically viable would put them out of business. They would make their product go up in cost to a large enough degree that people wouldn’t purchase their products. And you can’t just wave this issue away by pointing out that the company is very wealthy.

So we have to ask whether it is economically viable to, say, collect the packaging. I imagine that country-wide programs to do this would be very expensive.

Of the ones you mention, I imagine that research is the most likely to be viable (keep in mind it’s not just the research but also finding a material that is economically viable to produce) But how do you know they aren’t already doing that?
