- Roma climate camp demands that the G20 governments take serious measures to counteract the climate crisis, a woman shouts into a microphone.

But she, like many other young people who dance, hit drums and march in the square, also wants to see a more just world.

Global justice is the main theme both on the street and inside the G20 summit.

- I think change is needed.

In every way: Politically, socially, for the environment, for workers' rights, for everything, says another woman in the crowd.

- This is where the future is created.

In the square, among us young people.

We are the next ruling generation.
