First of all, I'd like to welcome the Minister's statement. The environment where all of us in Wales live is not only the areas of outstanding natural beauty, the national parks, the farms and the countryside—it's areas where people like myself live. Within Swansea East we had a mass tree planting programme in the 1960s and 1970s, and the lower Swansea Valley where I was born was the largest area of urban dereliction in Europe. It was transformed by the lower Swansea valley project, supported by Swansea council and Swansea University, and involved mass tree planting.

The Neath Road in the Hafod in my constituency has the second poorest air quality in Wales due to a combination of traffic and topography. The Morfa Distributor Road has led to a reduction in  the traffic on Neath Road, but it's still a major cause of air pollution.

As you have mentioned non-native species, I'm not going to go on about knotweed again, but there is a serious environmental problem with these non-native species. And it's not just knotweed, though that's the major one in the Swansea area. You have others, like Himalayan balsam, and you have some others in other parts of Wales and they are a serious problem. When we talk about the environment, we keep forgetting and not mentioning and not talking about it, but we really do need to address these, because they're having a serious effect.

I've only got three questions. What is the Welsh Government going to do to transform other areas of urban dereliction? What is the Welsh Government's proposal for increasing urban tree coverage? And not just planting some trees or some more woods in an area, but actually having trees in areas where people like myself and my constituents live.

And what proposals has the Welsh Government got to improve air quality, especially in the areas of very poor air quality? And there are a number of those. I see Hefin is not here at the moment, but he can mention a place in his constituency. I can certainly mention the Hafod in mine, and there's also Fabian Way, which is in both David Rees's and my consistency, where you have the topography and the volume of traffic and the fact that traffic keeps on stopping and starting because of the volume of traffic, which really does have a serious effect on the environment of the people living there. In a lot of these areas, there are people living closer than I am to the Presiding Officer away from the main road. Some of them are as close as I am to David Melding from the main road. I think that really is a problem. The cars are stopped outside their houses and then they're starting up again and it's sometimes the width of a pavement away from their front door. I'm a great believer in the 'worst first' philosophy and policy, so what can be done about the worst areas of pollution and air quality?
