What is your solution reining_girl?
Because while I hate to see horses slaughtered (And yes, I know cows and sheep and pigs get slaughtered too...but I will be honest, horses upset me more because of my closeness with horses over other slaughter-bound animals), I see it as a necissary evil.
Even if we close off slaughter in canada, mexico, and the US, it's still going to happen because of the high demand for hose meat in European and some Asian cultures. If we can keep it in the USA, we can better regulate it as well as export and make a profit off of it (since after all, this is all a business).
There aren't enough horse owners who want to or can adopt. People who already own horses are having a difficult time.
So far, I can't see a solution.
