We create so many deep holes, that it’s believed the tunnels we make will be our species’ legacy once we cease to exist on Earth.
As human civilizations go, we definitely dig many really deep holes. We create so many in fact, that it’s believed the tunnels we make will be our species’ legacy once we cease to exist on Earth.
Sure, a lot of people imagine that a post-human world would be filled with vacant skyscrapers and relics of other architectural feats.
According to geologist Jan Zalasiewicz, underground is where the surviving fruits of our labors will be.
He points out that never before in the history of the planet has anyone or thing riddled the Earth’s crust with so many hollows.
Given the astounding depth of a lot of them it’s highly unlikely they’ll ever be filled by time or natural phenomenon.
Mining, nuclear testing, and toxic waste disposal are examples of the kinds of activities that have forever changed the landscape.
So much digging has gone on over the years that if all boreholes, large and small, were combined they’d extend from Earth all the way to Mars.
The bulk of this activity has occurred between the 1800s and today.
