I'm not sure whether that would be feasible. The current rate of meat consumption in affluent countries is already straining the global amount of resources, and projections suggest that meat consumption is on the rise. Increasing animal welfare while keeping production constant (or even scaling it) will be even more inefficient and will require even more resources. So this only seems feasible if you reduce the overall rate of consumption, and how would you do that more effectively than by promoting vegetarianism or something similar?
