What's all the fuss, since weed is legal, almost, got to try something else. Big deal, I read now they don't think it was as bad as originally thought, and the ozone hole has shown signs of repairing itself. While 134 doesn't seem to affect the ozone layer, it does increase warming potential, and with all the A/C in the world, it should be no surprise with the warmest year on record, we are certainly screwing something up. Just too late, as I heard, if it wasn't for A/C, places like Phoenix wouldn't exist.
