I'm happy that evolution have solved that problem for you, cantleave.
And that has made you completely insensitive to it, because, after all, those are the losers on the intra-species evolutionary competition for resources, the driving force behind adaptation. Social darwinists must smile when they see such photos, because it constitutes scientific evidence of the mechanism for determining the best-suited group; politically, economically and ecologically.
Being a darwinist, I suppose your conscience driven by evolucionary tenets isn't hurt at all. After all, it's the survival of the fittest in operation.
It all makes perfect sense when explained by evolution.
