90% of farmed animals globally are in factory farms: https://www.sentienceinstitute.org/global-animal-farming-est...

I don't have data on the West specifically, but I'd be surprised if it's not 99%. "Free range" animals are largely a fiction.

Animals being used for pasture grazing, for the benefit of the climate, could be understandable, but I think enslavement and torture of 200+ billion animals annually is a moral failure that goes far beyond its effects on CO2 ppm.
