I think it entirely depends on the timescale. I like to imagine a distant future where all food production is automated. Staples, vegetables, and fruits (and fresh water) would be available to everyone for free. People wouldn't eat meat because of the environment. People wouldn't grow up eating meat, so eating a cow would be just as repulsive as eating a cat or a dog. It wouldn't even be a temptation. > They’re so large, astronauts can see entire sections of the planet turn brown and die every Spring as farmers nuke the soil’s native biology to make way for the artificially imposed order of the grain field. I don't know what to make of "artificially imposed order of the grain field." People have been artificially imposing order on the earth for thousands of years. Granted, it's on a much bigger scale today. Still, how do you propose feeding the earth without any artificial order? In this future world, all of the machinery will run on solar and wind power. We will grow genetically modified crops so that we only need to use a small amount of pesticides and fertilizers. And just like all plants, these crops will absorb a lot of carbon dioxide and release a lot of oxygen. I mean, even if this is still bad for the environment, would there even be any room for improvement? The only thing I can think of is somehow reducing the human population. That's a prickly subject. And we're going to really have to think about all of this before we defeat aging.
