If you can point me to any resources you've found to support this, I'd be happy to read them and revise my view. Besides the power/construction overhead, the infrastructure costs, and the lack of political will, many large coastal cities will likely see partial flooding and increasingly frequent weather events this century, while some are at risk of complete loss. The meat issue is complex. Lab-grown meat is subject to many of the same power and infrastructure constraints as vertical farming; I don't see it scaling to sustainably meet (meat? ;) current demand. We need a massive reduction in meat consumption in the developed world, but we also need to be conscious of the fact that ruminants remain critical to many agricultural ecosystems. We should certainly stop razing the Amazon for cattle pasture, although that will require a dramatic shift in economic incentives.
