Im honestly not sure how to explain it to you in a way that hasnt been done on this thread already. Most pro-slaughter people are also pro-slaughter regulation. We fight to try and make sure that animals are killed in the most humane way possible while still being okay to consume and we work to prosecute those who do not follow regulations. That doesn't go just for horses but for swine, cattle, birds, etc.
If it were up to me, it would all be done local. But since that is never going to be the case, we have to work with what we have.
Since the slaughter plants in the USA have closed, exports to Mexico have increased 312% an amount of around 44,000 horses. Once horses leave our borders there is nothing we can do and that is why I want slaughter plants open here.
What if we banned exporting the horses, consumption of horses, everything all together?:
"The AAEP estimates an additional 2,700 rescue facilities would be needed in the first year of the ban to care for the thousands of surplus horses. The costs of euthanasia and environmentally safe carcass disposal can run as much as $400 and may be more than some owners are willing to pay. Making matters worse is a hay shortage, brought on by droughts, which is making it more expensive to feed horses." (AVMA.com)
Not only that, but until the world becomes vegan, there is always going to be horse slaughter. Here at least there are regulations and ways to prosecute those who are not up to standard. The same can not be said for local butchers and backyard slaughterhouses in Mexico and the rest of the world. Once we end slaughter (hypothetically) in America, I imagine you would want to move to Mexico, Canada, France, Belgium? What happens to the thousands of horses that go to slaughter every year? Obviously they do not have a good home waiting for the majority of them. Where do they go?
Right now, ending slaughter and the consumption of horses is not a feasible option if you agree with eating horses or not. Until we come up with a solution, our best weapon is to make sure the horses die as humanely as possible. The first step to doing that is keeping our horses in our control instead of exporting them for another place to deal with.
