Regardless of one's stance on global warming and whether or not humans contribute to it, I would hope that we can all agree on the necessity of environmental stewardship. It's deplorable that many bodies of water cannot be swam in (let alone fished from), that breathable air which does not contribute to asthma and lung cancer is a luxury, and most of all that this happens because corporations place the cost of these externalities on society without adequately paying for it.
