I imagine the ultimate solution to non-human welfare as follows:
(Trans)humans do not kill any life to survive. This include lab-grown unicellular life. All transhumans are mind uploads (ems) whose subsistence needs are fulfilled by electricity and raw materials to build new hardware
All the agriculture and heavy industry is located in space. The entire Earth is preserved as a wildlife park
All death is eliminated, human and non-human:
Smart-enough non-human life (chimps etc) is uplifted and uploaded
At the earliest possible opportunity, the rest of the biosphere is cryopreserved (or placed in a stasis by other means), to stop all death, “natural” and anthropogenic. We decide what to do with the biosphere after we got enough compute for such a complex decision
From this point of view:
mind uploading research could be the most efficient long-term animal welfare measure
asteroid mining might be the second most efficient measure, as it is necessary for moving all industry to space
the most ethical dietary choices are the choices that help with the transition to the described future:
if your research helps with the transition, eat healthy food that prolongs your life (e.g a lot of greens and almost no meat). The longer you live, the more you can contribute to the research
in general, reduce the consumption of cattle-derived food, as it indirectly slows down the transition (cattle → global warming → negative economical impacts → less money for the relevant research)
