You wanna see cannibalism waits till there are ten billion humans running around and the era of liquid hydrocarbons comes to an end without a replacement energy source of equal magnitude in place.
Or just wait for a class X or larger solar flare to cook the world’s energy grid and the lights go out for good. Civilization will crumble in days if not hours. There will be cannibalism on a scale not seen in history once either of these two happens. Civilization is just a thin veil over the true barbarism that humans are. We are a savage species unlike any other on this planet as we have the large brain cases to house a truly diabolical mind. We get creative in our barbarism.
The Great Tribulation
15 “Therefore when you see the ‘abomination of desolation,’ spoken of by Daniel the prophet, standing in the holy place” (whoever reads, let him understand),
16 “then let those who are in Judea flee to the mountains.
17 Let him who is on the housetop not go down to take anything out of his house.
18 And let him who is in the field not go back to get his clothes.
19 But woe to those who are pregnant and to those who are nursing babies in those days!
20 And pray that your flight may not be in winter or on the Sabbath.
21 For then there will be great tribulation, such as has not been since the beginning of the world until this time, no, nor ever shall be.
22 And unless those days were shortened, no flesh would be saved; but for the [c]elect’s sake those days will be shortened.
