The control freaks would have us believe that cows produce enough methane to make a tangible impact on global temperatures. I'll leave aside the perfectly good arguments that no, they don't, because that will only lead to endless argument about whether or not this bunch of stats is more "true" than that bunch of stats, an argument that could go on forever. 

Instead I'll just ask, where does the carbon come from, that these cows make into methane? And then seeing as this is an article and not a conversation, I'll have to answer it too. It comes from the vegetation that they eat. And where does the vegetation get it? From the atomosphere, of course! And the vegetation re-grows after the cows have eaten it, soaking up the same amounts of carbon. It's a cycle. 

Cows are carbon neutral. 

That's all we need to know. The control freaks want us to believe a lie so that they can take even greater control over every aspect of our lives. You may find that difficult to  accept, but that's because you are not mentally ill like they are. You need to imagine not a sane, reasonable mind, but a twisted, sick mind in order to understand what out rulers are doing.
