Existential risk

I’ve been reading about existential risk lately. This article is not immediately relevant to Mars or our future there. But it also kinda is.

The Tanis fossil site, in North Dakota, appears to be showing us creatures directly killed by the Chicxulub asteroid impact. The picture of that leg is reminder that “geologic time” includes now, just as it did for these organisms on a day that changed the world, 66 million years ago.

From the article:
“We’ve got so many details with this site that tell us what happened moment by moment, it’s almost like watching it play out in the movies. You look at the rock column, you look at the fossils there, and it brings you back to that day,” says Robert DePalma, the University of Manchester, UK, graduate student who leads the Tanis dig.
