Literally impossible, due to energy/biomass transfer up the food chain. The bottom will always be the most efficient.
Picture illustrating this
Except that you can't eat grass.
Most meat eaters are not eating meat that feed on grass. Mostly it’s corn and wheat which humans can eat. If we even made the simple change that banned meat consumption of non grass fed cows that would mitigate 90% of the issue. Also beef will cost like $100 a pound, so
What do you mean most? There's no corn/wheat fed meat in Europe. And pretty much anywhere else except for US. Growing special food for animals when you have shitloads of free grass is dumb.
The use of corn-based feed for animals seems to be a universal trend. In Europe it's done less than in the US, but it's an option everywhere and driven by prices. And those prices do not consider the CO2 cost to the ecosystem.
