Honest question. Why make meat? Why not use your resources to create nutrition bars? You have to source everything the meat needs to grow anyway (and what are those sources/impacts?), why not just press it in a bar and be done? If you're afraid folks will really miss their meat, so you want to ply them with meat, let me just say - folks who love meat will find the meat they love. They won't likely shift to reactor meat for environmental reasons.
Conscientious meat lovers will invest in regenerative agriculture, lobby for ending corn feeding, reclaim all that land, return it to natural grassland, and let ruminant animals do what they do best -- feed the soil and make meat.
