What's Mallard raving about today?
Cows, the U.N., greenhouse gasses.
In my time doing this blog, this particular panel may be the single stupidest and wrong-headed premise yet (though by no means the most offensive). There are so many things here worth comment that I am just going to pick the two most obvious and leave it to commenters to pick the rest of it apart.
The algebra at work here is that cow farting and belching is as much of a biological imperative as other forms of human greenhouse gas production. I don't know about cows, but I could definitely stop driving my car before I could stop farting.
The idea that a cow could retain enough methane gas to float before exploding is quaint, but worthy of Mythbusters. And yet, the position of the footnote asterisk is quite interestingly placed in a way that it appears as if the U.N. is the source of this particular idea. Highly subtle hating on the U.N.
