"Some 72,000 wild equines live on public lands, about three times as many as the land can support. "

I'm normally pretty conservative on most issues, but I don't buy that claim.  The federal public lands amount to 2,265,625 square miles, most of it in the West.  1 square mile = 640 acres.   A lot of it is desert unsuitable for horses, but when the total amounts to over 20,000 acres per wild horse, I have a hard time believing that there are too many horses for the land to support.  The cattle business is over-reaching.
