Obama to Introduce Cow Fart Tax

[True Federalist (진정한 연방 주의자)]

Methane is a fairly powerful greenhouse gas, and there would be health benefits to discouraging meat consumption.  Doubtful that it would be do much, but it wouldn't be that difficult a tax to collect.  Swine and beef cattle could be taxed at the slaughterhouse.  Self slaughtered pigs and cows are a small enough portion of production that letting them slip through this loophole wouldn't be a problem unless the tax rate got ridiculously high in relation to the underlying value of the meat so as to cause people to try to bypass slaughterhouses to avoid the tax.  Dairy cattle could be "taxed" by reducing the amount of price support given to milk

That said, trying to use the Clean Air Act to target greenhouse gases is the wrong approach.
