Chapter 1: What geological changes would occur if North America disappeared?
The geological thriller four and a half billion years in the making. If 100 million years is a minute, minute zero is just a hot, loud, molten mess. It takes two minutes of vivid lava flows and rain so heavy it can fill an entire ocean before the Earth cools enough to grow a crust. Jump ahead 14 minutes and that crust cracks like an eggshell.
Earth starts playing a massive jigsaw puzzle, probably looking over at Mars and thinking, you just couldn't pull this off. For the next 30 minutes or so, supercontinents assemble and split. Oceans open and vanish, constantly reshaping the stage for life to flourish.
That flourishing required a solid foundation and for billions of years that anchor was Laurentia, the ancient stable core of what we now know as North America. Welcome to Life Without, where I pull a single thread from our magnificent world. Something we take for granted, just gone with my powers. Poof. No warning, no clever workarounds, just the unravelling. How far will it run?
Can we stitch a patch and survive the wear and tear? For BBC Radio 4, this is Life Without with me, Alan Davis. And together, we'll find out if a life without North America ends up unpicking reality as we know it.
We'll look upon that event as this marker in time. You know, we will be in a new geological epoch where we begin to witness the birth of our planet through a new lens.
Embarking with me on this journey, earth scientist, presenter and author of The Whispers of Rock, Dr. Anjana Kandwar. An environmental campaigner and author of It's Not Just You, How to Navigate Eco-Anxiety in the Climate Crisis, Tori Chow.
The first thing that crosses my mind is the chaos that will ensue and how is this going to affect the energy transition and perhaps forge a greener future?
North America is the third largest continent, a colossal backbone of rock and life that bridges two oceans and two worlds. So in a bold move, I'm pulling the landmass of North America right off the board to see how the rest of the pieces flux and reshuffle to fill the void and keep life going forever. Anjana, if we listen to the Earth right now, what will we hear?
We're hearing the oceans coming in and flooding into that void. The North American plate is about several thousand kilometres wide and about 200 kilometres thick. So what we're going to see is the exposure of the mantle underneath that continental crust that has been vanished entirely. And as the oceans flood into that void...

Chapter 2: How will the loss of North America affect global energy production?
There's a lot of volcanic eruptions.
Those eruptions eject into the atmosphere particles of all sorts, but especially volcanic glass, which is incredibly dangerous for jet engines. So we are going to have to really change our behaviours in the aftermath of this. So 100 years down the line, our descendants will have understood how to survive, how to become more resilient, how to travel around in a different way.
And those stories would have been passed down.
North America took Silicon Valley with it. Have we lost our global megaphone? Tory, what do you think?
We're losing about 45% of global data centers. So that would cause an immediate contraction in year zero. A hundred years on, who would fill the void? I'm immediately thinking of countries like China and India, who have their own social media infrastructure. I'm also thinking about AI. We're in this current of such proliferation of AI, and America is leading a lot of that.
There might be a shift to the different global superpower running the social media landscape. It might also democratise social media. Maybe it will result in more grassroots and more equitable forms of communication that are localised and don't rely on this algorithmic obsession with likes and shares and reactivity in a space that's very polarising.
Angela, if we stay in this timeline, paint us a picture of the Earth map in, say, half a million years or a million years.
Geologically speaking, we're going to see the formation of a brand new continent where you start to see the emergence of those volcanic islands grow and coalesce together to form new land. It'll be interesting to see how that begins to influence and change humanity if indeed humanity still exists.
I started this experiment by deleting a continent and ended up rewriting the entire history of the Earth. It turns out you can't just remove a massive piece of the puzzle without the whole picture falling apart. Because it's not just land. It's a carrier of culture, of human brilliance and millions of years of evolutionary records.
