Diolch, Heledd. I share your concern. I've actually, before I had your question in fact, raised with my own officials my own perception that the amount of litter along particular roads and train lines has increased in recent years, and I think there are a number of reasons for this, which we are looking at. So, I am very keen to strengthen the ability of local authorities to take action there, both, actually, retrospective action to pick the litter up, but actually some behaviour change and education programmes for people to understand the real impact of throwing a bottle out of your car window or whatever it is. There also is an issue with the way that some waste contractors pick up skips without the correct netting on the top and so on, and blow-off from that. So, I'd already independently—and I'm more than happy to renew that—asked for a review of how that system works, how we fund it, and what the relevant duties are. We have the responsibility for some of the trunk road network, but we delegate that to local authorities, and I've asked for a review of that as well.

So, I share your concern, and I'd already started the process, but I'm very happy to invigorate it again, of looking to see what else we can do. But I do think there is a big behaviour change issue here. People really do need to understand what happens when they litter, what happens to the plastic that they leave on the side of the road. It's not just that one bottle, and what happens as that leaches into the environment on a longer term basis. So, as I've said, we've been working with Jeremy Miles, with the Eco-Schools initiative, to really drive home to people the effect of their individual behaviour, and a lot of this will be as a societal push, won't it, to making such behaviour just completely unacceptable.
