I thank the Minister for her answers, in particular about Port Talbot, and identifying the actions you're taking. However, it's not just PM10s; it's PM2.5s as well. And knowing the area, it's not just the industry and the steelworks; it's also the motorway, which is caught on that narrow strip, and the roads on the side of it. So, one of the ways you can actually look at it is to actually look at planning, and maybe talk to your Cabinet Secretary colleague about planning regulations. Look at the cumulative impact of any decisions taken upon air pollution, not just the individual project, because the more we see coming in, which creates more pollution, it adds to what's already there, and what's already there is not getting lower. So, please look at the issue so we can ensure that we do start seeing a decrease, not an increase.
