Most cows alive wouldn't even exist if it wasn't for them being bred to produce meat and leather. I claim their right to life trumps these morons right to some sense of arrogant, misplaced self-righteousness.
Anyway, since when did Tesla's mission statement have anything to do with saving animals?
Also how does wastefully throwing away the skins of cows bred/killed for meat as opposed to reusing them to make useful, durable leather goods make any logical sense in any argument about caring for the planet?
