That's really helpful to understand, especially with 2,000 premature deaths and £1 billion of expenditure with the Welsh NHS. That's the cost of dirty air on people's lungs and associated health conditions. Very often, when we talk about legislation, we are told that the Welsh Government lack bandwidth. Last week, in a statement, the Welsh Government made it known that they want to apply for the gender recognition powers so they can bring a piece of legislation in that particular area. Why on earth are not all the efforts of the Welsh Government being put into bringing this piece of legislation—the clean air Act—which, hopefully, will come this year? We have had it promised before and it hasn't arrived. Why seek more powers when the current powers that you have are not being utilised to improve people's lives here in Wales?
