I'm also pro humane slaughter. Unlike most of those folks who write those articles about how "horrible and completely wrong" horse slaughter is, I've been in the trenches, so to speak. I've seen what the lack of slaughter has done to the market and the effect that has on the general horse population...and those of us trying to care for them.
Couple the lack of slaughter with the economic decline and the massive, widespread drought that many of us have suffered in recent years, and it's a recipe for disaster. The worst part is? The horses are the ones to pay the price, being turned loose on public land to fend for themselves or being left to starve in some back pasture somewhere because the owners simply can't afford to feed them and nobody else will take them, even for free.
