Burping of the lambs blows roast off menu.

GIVE up lamb roasts and save the planet. Government advisers are developing
menus to combat climate change by cutting out “high carbon” food such as
meat from sheep, whose burping poses a serious threat to the environment...

Out will go kebabs, greenhouse tomatoes and alcohol. Instead, diners will be
encouraged to consume more potatoes and seasonal vegetables, as well as pork
and chicken, which generate fewer carbon emissions...

The problem is because sheep burp so much methane, a potent greenhouse gas.
Cows are only slightly better behaved...
