I also agree that ethical sourcing is pretty ridiculous given real world constraints, but I’m holding out hope that someone figures it out.
It’s not hard to figure out, it’s just not economically viable to set up a system for it when the alternative is just not worrying about ethics and doing it anyway. We struggle to get companies to pay slightly more for recycled plastic than virgin plastic, this isn’t any different.
By “figure it out” I meant “figure out a way to get big companies on board”
You do that by banning or disincentivising the less ethical option, the moment it’s less economically viable, they’ll pivot, unless it isn’t an option.
