It is definately a complex problem. Maybe 3D printed meat will save the day.
As an anecdote, I was on a trip to Spain once, when I saw a documentary on octopus intelligence. That same day, I went out to a place where everyone was drinking wine and eating octopus. That's the tradition there. Imagine me surrounded by all those happy people drinking and eating octopus. Had I not watched that documentary, I would have partaken of the octopus party. As it happened, I did not. I still regret it in my weak moments, but to this day I have not touched another octopus. :)
