This is John Bachelor, conversation Nomad Century by Gaya Vince, how climate migration will reshape our world.

Gaya addresses directly the migration story which is in Europe in the Americas in Asia now

global South moving global North why and what is to be done. But here, Gaya very clearly challenges the presumptions of the prejudices,

the assumptions about migrants coming to the north very carefully.

And it is positive in that the populations receiving the people from the global South are tolerant. The

leadership is not. There's Giah Vince, Nomad Century. More of this tonight.

It's absolutely not and this is this is absolutely key to the problem that we face.

I mean at its heart it's racism, it's tribalism and it's generated by all sorts of different things from fear, fear of losing your job,

fear of being overwhelmed by other people that want the same access to services and so on. These are not the fault of the migrants.

There is so much evidence now out there that migrants, they actually increase productivity.

When it's managed well, they increase productivity of cities.

They don't reduce wages.

They actually raise them.

They don't increase unemployment, they actually reduce it,

they don't increase crime rates, they reduce it.

There is so much evidence from across the world from multiple cities in the United States, from Israel, from Europe,

from across the world that this is the case.

But unfortunately we are living in a time of increasing nationalism of populist leaders and this very worrying

ethnonationalism, this idea that a people belong to a place by merit of what they look like, of how much melanin they have in their skin.

And first of all, this is biologically, completely inaccurate. We are so closely related that there is no, that you can't tell where somebody, where somebody's ancestors are from purely by looking at them anymore and we are

incredibly mixed up but there is more there is more genetic difference between two chimpanzees living either side of the

Congo River than between two populations of people living on different continents. We are the same, we are the same. And we need to accept that. We also need to accept that migration is going to happen and that it is largely going to be from the global south who have largely darker skin than the people currently occupying most of the global north. So that is going to happen, to what degree it happens and how it happens in terms of the disruption to our society. These are are things that we can do something about.
