Andy_Spoo writes "Something that I've been trying to get an answer to: Is alcohol killing our planet? Alcohol is a byproduct of yeast, but another is CO2. As we all know (unless you've been asleep for years), CO2 is helping to warm our planet, sending us into destruction. So how much is the manufacture and consumption of alcohol contributing to the total world CO2 level? And don't forget that bars and pubs force beer through to their pumps using large compressed cylinders of CO2. Does anyone know?"
