Horses have formed a partnership with mankind until about 100 years ago. That is when we began to use oil as an energy source. Since that time we have become so dependent on oil that our survival on this planet might be questionable now without oil. Oil is finite. 100 years ago we had no oil and horses 100 years from now we will have no oil or horses. The BLM is rounding up our American Mustangs at such a rate that now more of them are in captivity then roam free. We must protect viable numbers so that the DNA that was created over five hundred years by survival of the fittest is preserved.
