A cow burps and farts between 160 to 320 litres of methane every day.
Recent research also suggests that methane is 28 times more effective than
CO2 at
trapping heat.
methane still makes up 16 per cent of global greenhouse gas
emissions.
所以，控牛势在必行。
要立法，牛肉限购，实名制，每人每周0.5磅，统一background check。超过0.5磅者，
交甲烷排放税200刀购买本州买肉permit，只能本人本州使用，有效期5年，到期后可再
交200刀renew。
