All this pussy shit about changing our entire eating schedule to reduce emissions by .01% is fucking dumb. The main problem is western habits and our dumb intake of everything! If the entirety of the US and EU disappeared overnight then emissions would drop by more than 75% even though the West doesn't even make up 10% of the world population.
Beef itself isn't the part that's emitting. It's all the transportation and handling and resources the beef needs. You can stop buying beef to lower emissions sure but you can't replace eating beef with just eating more other shit that might also emit just as much.
This is a red herring but you know that grass fed cows don't produce as much methane right? You know there is a considerable amount of energy used to maintain the cow right? This is energy that would be used almost regardless if we are to increase consumption of grains rather than cows which is the problem. We are going to get fatter as a civilization if we start eating less meat.
