The legacy of wild horses in the West is somewhat complicated. They are iconic, evoking images of a lost, wild and romantic West. On the other hand, they can be pretty damaging to fragile dry-land vegetation and cause a good bit of erosion. On the third hand (since this is extra-limbed creature day at LGM), they are related to a long-lost indigenous species of horse that populated the West until the Pleistocene era.
Even if you think wild horses aren’t a great thing, it’s hard to understand a “long-time advocate of horse slaughter” who is buying horses from the Bureau of Land Management and shipping them to Mexico for slaughter. Talk about a dirty (and illegal) way to make money.
