Edibles available after a catastrophic global disaster would be enough to sustain most people, but the food might not be very tasty or appealing, suggests new research.
Even some of the worst possible doomsday scenarios, such as an asteroid strike or nuclear winter, are projected to leave behind enough resources for most people to survive on, according to the new book "Feeding Everyone No Matter What."
Joshua Pearce, an associate professor at Michigan Technological University, and David Denkenberger, a research associate at the Global Catastrophic Risk Institute, coauthored the book.
Bacterial slime, they say, would be one important food option.
"We are talking about humans eating mostly bacteria-digested biomass," explained Pearce.
As for what that would taste like, he added, "Let's just say you are unlikely to see it on a menu at any restaurant, unless the sun gets blocked."
