yes. when you look at charts and such. Someone who exclusively ate meat for some reason who moved to chicken would have a greater impact than someone who exclusively ate chicken and went vegan. Sheep did not show up so well either so im guessing ruminants in general are not going to be so hot. Anyway I would encourage folk to keep it in mind and do what they can. I realize go vegan results in many. Well eff it all then but man just avoiding beef is big impact.
