"Instead of stopping exports, why dont we threaten to stop exports unless we see vast improvements in the way these animals / commodities are used and give a timeline? That has a far better chance of having a positive result against this barbaric treatment of animals."
You said yourself in another part of your post: we have no control over how the other end conducts their affairs. But, we do have control over who we want to sell to.
It is totally unacceptable for the animals to be killed that way.
