This is CBSI in the world. I'm John Batson with Gaya Vince. Her new book is Nomad

Century, How Climate Migration Will Reshape Our World. We begin with the migrants of the Global

South, needing to move because of the four-horsmen of the Anthropocene,

which is the debatable era replacing Holocene is where we live right now.

However, there what can go wrong and why?

We know it.

It's in the news already.

Borders.

Or the interception of human traffickers in the Mediterranean or in the North Sea, turning back people who are looking for anything better than where they're coming from because of climate

change and because of bad governance. Bad governance and climate change tend to go together.

It might be a phenomenon. It might be a one-to-one correlation. But I mention the fact that we're all migrants.

Gai, it's not only my family and all of our families here in America, reading through a

history of Julius Caesar, he built his reputation on his brutality towards the tribes of Germany

and France that were moving in Gaul.

That he slaughtered them in great number and bragged about it back in Rome.

We've been moving for thousands of years and has determined our histories.

But borders, borders were important to the Romans.

Borders are important here in the North America.

What needs to be done about borders? How do we rethink our borders? Yeah, well, you're absolutely

right. We've been moving not just hundreds of years, but hundreds of thousands of years.

I mean, we're an ape that evolved somewhere in Africa, two to three hundred thousand years ago.

And look at us now.
