Many of the "wild" burros and horses are NOT wild, but rather feral animals that have been dumped because their owners could not afford to keep them.  The populations continue to soar because there are no natural predators to keep numbers down and in bad years, these animals are suffering from starvation and dehydration.  This is their reality.  The wild west and romanticization of the "wild" horses is nothing more than an emotive fantasy.   The BLM is required to "manage" the lands, that includes the animals that dwell on them.   They cannot sustain huge populations of these animals.   So what then?   While they do round ups and try to place as many as possible, the numbers remain.   There has to be a way to control the overwhelming numbers and the most plausible solution is to send the excess to slaughter.   We need humane slaughter in THIS country to allow these animals a quick and painless end to the suffering not shipped thousands of miles to other countries.
