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%.

    You realize you are trying to discuss rationally the administrative problems of a policy with people who have no trouble with the idea of setting up an Orwellian police state to enforce those policies, and with no real concern about the ostensible goal.

    It's going to take a lot more than small changes across the board to fix our OC2 output, it requires complete changes.

    And it's pointless complaining about economic cost when the cost of doing nothing is likely 20 times as much.

    People in western countries have gotten used to living lifestyles that are completely unsustainable and worse many have gotten it into their thick heads that they are somehow entitled to these lifestyles like they are royalty or something. Just suggesting that people need to live their lives differently causes them to get angry and spout complete stupid crap and excuses. Humans forget, they are an animal and depend on the rest of the ecosystem to exist.

    Nobody but you mentioned governments forcing farmers to do anything

    LOL sure, and the use of government force never happens on these issues.

    Pull the other one.
