It's frustrating to see arguments devolve into this kind of thing. It's almost surely the case we are discussing developed nations like the US (one of the largest consumers of meat), not some remote village in a developing nation. Sure there might be remote places with no access to the world market. Sure there might be some people whose health doesn't allow removal of meat. But on the grand-scale of the US and other developed economies, we can reduce meat consumption by 90% without any negative effects (in fact, we'll improve average health by a lot).
