IMHO, This is entirely within the scope of the industry itself to fix. Fund an international governing body that can have animal welfare standards, certify them, and market them to the policymakers as an alternative. This will only work if the process is transparent, though - otherwise the calls of corporate greenwashing will come.
These sorts of successes came with the sorts of certifications you see from the FSC, Certified humane, and other bodies. The key is to actually focus on what’s best for the animals, make it clear that’s the point, and involve the NGO’s.
The issue with that is that it only helps consumers know what’s going. It entirely leaves the actual practice up to the free market, which we’ve already seen leaves the base line on animal welfare low.
More over you tend to get a proliferation of slightly different certifications, which still leaves a lot of confusion.
But that line was directed at the movements most focused on these bans. On the whole they refuse to accept the idea that humane treatment is possible, especially for things like foie gras. And as a result often actively undermine attempts to impose standards.
In order to accept what you’re saying in that post, I would also have to accept the idea that animal rights activists are using irrational and dishonest arguments to sell their policies.
