An absolutely valid point, and I'm glad you made it because it's important that we do remember that as well.

It disproportionately affects, of course, people in deprived areas, which, again, is something that is of huge concern. We know that both short and long-term exposure to ambient air pollution can lead to reduced lung function, respiratory infections and aggravated asthma. Maternal exposure is associated with adverse birth outcomes, such as low birth weight, pre-term birth and small gestational age births. There's emerging evidence also suggesting that ambient air pollution can affect diabetes and neurological development in children. It can cause, as we know, many cancers, and some air pollutants are also linked to psychiatric conditions.

As Plaid Cymru environment spokesperson, of course, there are ecological effects as well. Air pollution can cause serious environmental damages, clearly to the air, but also to the groundwater and to soil, and it can seriously threaten the diversity of life. Studies on the relationship between air pollution and reducing species diversity clearly show the detrimental effects of environmental contaminants on the extinction of animals and plant species.

Many Members will be aware that we have, of course, a cross-party group on a clean air Act in this Assembly, and Dr Dai Lloyd chairs that. I have to say, when Dai used his short debate, a number of months ago now, to call for an Act, he shared with us one thing that really stuck with me: 150 and more years ago people tolerated dirty drinking water, and we look back and we think, 'How outrageous was that?' Well, we're tolerating, or we have been tolerating, dirty air. In years to come, we'll be looking back in the same way and thinking, 'How on earth did we ever imagine that we could tolerate that?' I hope now that people are realising that the time has come to act.

So, moving on to our amendment, clearly, as I say, we're supportive of the motion and the principle behind it, we just wanted to maybe articulate a bit further some of the actions that we feel are needed.
