This is an article from Syfy channel, and it's a rather satirical article referencing the 70s movie Soylent Green where the twist is that everyone's food in the future is made up of people. The article is just a puff piece for social media looking at the movie and what the "realities" would really be if we ate the people who died. They run crazy click bait articles like this so it looks outrageous and people read it or share it because it's something ridiculous and get people talking about it to give them clicks. Looks like the marketing is working just fine, considering everyone here is now talking about it like they hoped.
