This document discusses the issue of unwanted horses in the United States. It notes that over 100,000 horses become unwanted each year for reasons such as economic hardship, injury, or lack of ability. Historically, many of these horses would be sold for slaughter, but slaughter plants in the US have closed down due to legislation. As a result, unwanted horses now face neglect, abandonment, or transport to Mexico and Canada for slaughter. The document examines various perspectives on how to address the unwanted horse population in a humane manner through adoption programs, euthanasia services, or reopening domestic slaughter facilities under stricter regulations.
