Give me a break w/ the 'carbon footprint' talk. The world periodically heats up and cools down- England was able to make delicious wine from their vineyards 2,000 years ago bc it was cooler then. Today finding out that English vineyards can make drinkable wine is a bit like hearing that an 80 year old millionaire has fathered a child- it might be vaguely within the realm of possibility but not a good idea. But if you want to let Obama via treaty put the United Nations in charge of the 'carbon footprint' of all carbon-based life forms in the USA then by all means...
Factory-farmed animals is what i try to avoid. If I can find jerky from a boar hunter who killed some wild pigs and took it to the meat processor to be processed w/ cheese and spices then that's different, or sushi. But buying meat at Walmart, McDonalds, or or any grocery store is not good. Factory-farmed grass-fed beef is only slightly better. At least when i eat sushi i know the tuna and salmon got to live in the ocean most of it's life. No doubt it would rather be swimming in the ocean but no i want it to be in my belly instead

You don't have to be a vegetarian to save the lives of hundreds of animals over the course of your lifetime and those u influence; just cut down on your meat- people can live healthily on 5% of the meat in the average American diet. Look at Thai or Indian food- those people know how to cook w nuts veggies fruits starches and/or roots. You can live much more healthily w/o meat eating deliciously but it takes a self-education, time, & energy.
