IIRC, most of its from their mouth actually. They're ruminants, meaning they're fermenting their food in their multiple stomachs. This is where most of the Methane is produced, and the pressure is released through their mouths.

No, it's mostly their poop.

The "cow farts" and "cow burps" phrasing is used to downplay the seriousness of the issue.

Global animal agriculture produces enormous quantities of cow poop, which produces enormous quantities of methane, which is one of the biggest causes of the climate catastrophe.

This says otherwise.

Anyway, yeah, I agree. It's all a distraction. I don't know how sayings it's poop helps. The problem is cattle farming produces a ton of methane. The details don't really matter.
