Thank you, Mike Hedges. You are quite right; climate change is the biggest threat that we are facing, and the advice that we're receiving is we've got 12 years to turn this around, and it could be that we are the last generation that can do that, and it's really important that we take the opportunity and that our children and grandchildren don't turn around and say, 'Why didn't you do something about it when you could?'

Mike Hedges raises a very important point, I think, around battery technology. I've been to the Solcer House—it was probably about two and a half years ago, and I remember thinking the batteries were very large that they were using then. Clearly, there's a lot of research and development going on to ensure that battery storage is getting smaller, because people will not have the room to have those large batteries. This goes for hydrogen as well—I think it's really important that we're not bringing forward technologies that people can't use easily. So, batteries are a classic example. We also need to make sure that the infrastructure is there. So, the national grid needs to be reinforced in parts of Wales—certainly mid Wales—and that's a matter for the UK Government to ensure is happening, and I'm having those discussions both with the National Grid and officials have also raised it with the UK Government.

Later this week, I'll be attending the British-Irish Council, alongside the First Minister, where energy is the topic. So, I'm very much looking forward to talking with colleagues from across the UK Government, the devolved administrations, and, of course, the Crown dependencies as to what they're doing. I'm sure there will be a lot we can learn.

Trees—I go back to my answer to Andrew R.T. Davies: we are not planting enough trees. You're quite right; there are commercial interests as well. It's not just down to Government to plant trees; there are lots of organisations that can help us. NRW, certainly, I think should be planting more trees, and I'm looking, as I said in my answer to Andrew R.T. Davies, to see what funding we can help them with.

I think you make a very good point about urban forests. The First Minister's manifesto commitment around a national forest—I think, in the beginning, when we were discussing a national forest, I was thinking of a forest. But, clearly, the options I've asked officials to work up point to many more smaller forests around Wales being joined up, but I've only received those options today. I will need to discuss them further with the First Minister, but I think there are opportunities to link up the forests with the coast path, for instance, to ensure that people recognise what they are and what they're for.

We have several schemes. You'll be aware of the Size of Wales scheme. We're now at twice the size of Wales schemes, with the number of trees that we've planted. And, of course, our Plant! scheme was set up back in 2008 to plant a tree for every child born and adopted in Wales—since 2014, we've planted a tree in Wales and we've also planted a tree in Uganda.
