Did ya see the BRILLIANT scientist John Kerry say's climate change is caused by cows and farming again! Lets see here, farming has been going on for a thousand + years. NOW all of a sudden Cow's and farming are creating the CO2 emissions. Somebody please tell me he's kidding right? This is the LIBERAL world we live in. Let's see, we now have Gas stoves, dishwashers, Gas water heaters, BBQ grills, Small engines and so much more I can't even think of. Every Liberal on here will say, OH this is the Republican rhetoric again.
