Honestly, I think the idea of selling human flesh is pretty much impossible or really unlikely to happen.. At least for 50 years. People might just try it to see the taste (curious rich people) but once the idea hits that we're eating human flesh. That thought is just really sickening because you don't know where they human has been, what diseases they've had, have drugs entered their system? Etc. I'm sure cannibalism is happening daily around the world, just I highly doubt it'll become popular, legal, and high demanding.
