Cows only produce 16% of our annual methane production [and 21% of our CO2]. They should be pointing their research in the direction of what to do with all the manure that the animal industry produces, which is 86,000 lbs per second.
One solution they've come up with is to put it in animal feed [dog/cat food, cattle feed, chicken feed, etc.] It's listed as "protein concentrate" in the ingredients. Yummy.
