I can count Bush's environmental policies on two fingers - banning of incandescent light bulbs (which, honestly, was going to happen eventually) and banning CFC asthma inhalers to support the Montreal Treaty, even though those were one of the tiniest contributors to ozone depletion and seriously impacted asthmatics (for one, it was the only over the counter asthma remedy, for two, the replacement, HFA inhalers, were patented, prescription only, and were only tested on healthy adults in the FDA's "fast track" program, which is the same thing they do to test GMOs, and 3/4 of the manufacturers used an allergen, alcohol, as part of the propellant, so that went over poorly...).
If there's one president I wish had failed to get into office, it's Bush, though Obama has cut it close a few times (both of them have TERRIBLE financial policy, IMO - defund Obamacare? Only the assistance to the poor was unfunded - Bush's Medicare D wasn't funded AT ALL)...
