Can't speak for Mr. Richards.  What I can speak to--and you can't, obviously--is the reality that there's no inherent moral or spiritual "advantage" to exclusively eating plants.  Like bears, we are omnivores.  We've been OBLIGATE omnivores most of our history PRECISELY because we chose life over death--by starvation.

Will you volunteer to carry fresh vegetables to rural Alaskan villages with no Carr's, Fred Meyers or Safeway stores to provide their dietary needs?  If not, these people will continue to choose life over death and provide food for themselves and their children by hunting and fishing.
