If an asteroid hit the Earth, half three
“So you burn things, kill everything in the ocean, and freeze the Earth, and it goes through about two years of constant winter,” Scharringhausen added.
He doesn’t suppose that each one life on Earth would die after a big asteroid affect since some small creatures survived the asteroid strike that when killed the dinosaurs.
Scharringhausen defined: “Not everything will die. If we’re thinking about people, the way to survive would be to get underground.”
“You could maybe ride it out in a bunker if you’ve got the supplies to make it through that period of winter where you can’t grow any edible food.”
“Maybe the finicky crops that humans like to grow won’t come through it so well, but there’s that seed repository, so if those are well-protected enough, you could get agriculture restarted.”
