Emissions from farming are also a huge issue that can't be ignored. I personally do not think it would be possible to farm the old way on this scale but it's a very complicated subject. I also know it simply will not happen because it would not be efficient or profitable. I like to focus on the lab meat because many top minds are studying it and many scientists are saying it is the future of meat.

Now, if people were willing to eat less meat, then farming may be able to change greatly but we eat (we, as in, Americans because that's all I have personally studied and is where I reside) A LOT of meat.
