> CO2 emissions/environmental effects of cattle are usually overblown.
Methane production from cattle is not a blip. Whatever statistic you pick, it's one of the major contributing factors to agricultural emissions.
We tend to consume too much meat. The US in particular is the top consumer of meat per inhabitant, like 300% more than the recommended meat consumption for a healthy diet (about 100g/day of red meat, before cooking).
So you can argue that an omnivorous diet is healthy, but we clearly over-produce meat and over-eat it by a very large margin.
I think quite the opposite - a beef-only diet, very high in fat, is probably the evolutionary diet we're most adapted too. After all we only started cultivating grains about 10,000 years ago. It was large, fatty megafauna for hundreds of thousands of years before that.
