Right there on the cover, it says.

But Rosamund knows that what they've done so far, it's not enough.

She quit her job as a teacher and became a full-time clean air advocate, giving speeches, starting a foundation and organising protests.

She wants our air to be cleaner.

She wants us to do the stuff we've been talking about since Captain Planet came out.

Burning less fossil fuels, having fewer cars on the road.

And the vehicles that are on the road need to be electric and run from the power of the wind and the sun.

We also need to be thinking about things like preventing wildfires.

Because scientists say that wildfire smoke in some places is starting to reverse the decades of progress we've made on improving air quality.

And, you know, Rosamund says that these changes, like getting off fossil fuels, we need to do them anyway.

What do you think Ella would make of this work that you've done and all of this?

We spoke to Rosamund in 2022, and since then, she's continued to fight for accountability after Ella's death.

Rosamund sued three UK government departments in 2024 and later received a settlement from them.

They wrote in a statement to her, quote, young children like Ella should not have to suffer because of our heir.

Meanwhile, Rosamund and her team have worked towards creating a bill that they call Ella's Law, or the Clean Air Human Rights Bill, requiring the UK to meet clean air targets by 2030 and legally enshrine clean air as a human right.

The bill was published just a couple of months ago and it's making its way through Parliament.

But over in the US, as we mentioned at the start of the show, things are moving in the opposite direction.

And experts say that those rollbacks, which make it easier for industry to pollute, it's expected that they will make the air dirtier.

And that could affect the health of millions of people in the U.S.

That's science versus.
