Want To Fight Climate Change? Stop Cows From Burping

sciencehabit writes: A simple supplement to a cow's feed could substantially decrease a major source of methane, a planet-warming greenhouse gas, a new study suggests. Each year worldwide, the methane produced by cud-chewing livestock warms Earth's climate by the same amount as 2.1 billion tons of carbon dioxide, a little more than 4% of the greenhouse gas emissions related to human activity. That makes cows tempting targets for methane reduction efforts. In a new study, researchers added the chemical 3-nitrooxypropanol, also known as 3NOP, to the corn-and-alfalfa-based feed of 84 milk-producing Holsteins and monitored their methane production for 12 weeks—the largest and longest such trial of its type in lactating cows, the scientists say. For cows whose feed included 3NOP, methane emissions dropped, on average, by 30%.

    Fat and docile, big and dumb
    They look so stupid, they aren't much fun
    Cows aren't fun

    They eat to grow, they grow to die
    They die to be eaten at the hamburger fry
    Cows well done

    Nobody thunk it, nobody knew
    No one imagined the great cow guru
    Cows are one

    He hid in the forest, read books with great zeal
    He loved Che Guevera, a revolutionary veal
    Cow Tse Tongue

    He spoke about justice, but nobody stirred
    He felt like an outcast, alone, in the herd.
    Cow doldrums

    He mooed we must fight, escape or we'll die
    Cows gathered around, cause the stakes were so high
    Bad cow pun

    But then he was captured, stuffed into a crate
    Loaded onto a truck, where he rode to his fate
    Cows are bummed

    He was a scrawny calf, who looked rather woozy
    No one suspected he was packing an Uzi
    Cows with guns

    They came with a needle to stick in his thigh
    He kicked for the groin, he pissed in their eye
    Cow well hung

    Knocked over a tractor and ran for the door
    Six gallons of gas flowed out on the floor
    Run cows run!

    He picked up a bullhorn and jumped up on the hay
    We are free roving bovines, we run free today

    We will fight for bovine freedom
    And hold our large heads high
    We will run free with the Buffalo, or die...
    Cows with guns

    They crashed the gate in a great stampede
    Tipped over a milk truck, torched all the feed
    Cows have fun

    Sixty police cars were piled in a heap
    Covered in cow pies, covered up deep
    Much cow dung

    Black smoke rising, darkening the day
    Twelve burning Mcdonald's, have it your way

    We will fight for bovine freedom
    And hold our large heads high
    We will run free with the buffalo, or die
    Cows with guns

    The President said "Enough is Enough!
    These uppity cattle, it's time to get tough"
    Cow dung flung

    The newspapers gloated, folks sighed with relief
    Tomorrow at noon, they would all be ground beef
    Cows on buns

    The cows were surrounded, they waited and prayed
    They mooed their last moos,
    They chewed their last hay
    Cows out-gunned

    The order was given, turn cows to Whoppers
    Enforced by the might of ten thousand coppers
    But on the horizon, surrounding the shoppers
    Came the deafening roar, of chickens, in choppers!

    We will fight for bovine freedom
    And hold our large heads high
    We will run free with the buffalo, or die
    Cows with guns
