I think the idea that red meat will always be far worse for the environment then other food is a bit of a red herring and conflated with ethics of animal eating. There are many factors not considered in those statistics such as nutrient absorption and protein quality. While it is true that carbon emissions are worse for grain fed animals (most of the red meat you see) it doesn't have to be this way. "Regenerative agriculture" claims to you raise carbon neutral (or negative) beef farms by restoring the native plant life and replenishing the soil. This won't feed the entire earth, but I try to support grass fed farms and obtain most of my red meat from them. Chriss Kresser offers some interesting points on this topic.
