It noted that there wasn't space for a male in accredited zoo's, and the other option would be circuses or facilities that couldn't guarantee proper care in adherence to the zoo's mandate. Sending to its homeland would have it dead within the week, having no herd of its own or experience living in the wild & evading predators.
If it could be trained & saddled like a horse it would make a pretty cool hunting ride. Just mount a GoPro to its head for scouting purposes
