From the BBC’s programme description:

“The UK government says air pollution is the fourth biggest threat to public health after cancer, obesity and heart disease.  We speak to a father whose daughter was rushed to hospital with breathing problems – he blames poor air quality. We’ll find out what the authorities are doing to try and reduce congestion.

Ministers have also committed to ending the sale of new diesel and petrol vehicles by 2040. But will we really all be driving around in electric cars?  A survey commissioned by You and Yours from YouGov suggests many people in the UK still aren’t ready to make the switch.”
