if you lived in an area that had idiginous tigers, surly you would learn to respect them and try to co-exist, just killing things for killing sake, is no reason enough, though your view comes as no surprise.
Errr... what? If tigers were roaming where my kids were, then I'd shoot them first and worry about endangered species second. As would, I think, any sane parent would.
Meanwhile, back to the discussion-in-progress... wasps can be killed without being overly concerned about the wellbeing of the planet, I think.
