As I mentioned, the environmental theme was an important one. What we focused on was this Lhalu wetlands area, which is in Lhasa. Obviously the Tibet Autonomous Region is a huge area.
One area that we would have for concern is mining. There's lithium mining that's been done. We've heard reports of poison in the waters. We didn't get to see any of the mining activity. There are some hydro dams that have been built or are being seen to be built. That also can have an effect on the environment.
I think, as China itself calls it, this is the third pole; the water tower provides the water for 1.4 billion people. Understanding the ecology and the environmental impact on the broader plane would be good. When we asked that question, what the official said was that they have, I think, 34% of the land area now in natural reserve. They have 47 natural reserves that are out there. I think the point is that we didn't get to see them. I think, again, we need to get access and have experts have access to be able to go and look at what's happening. Clearly China's saying it's a priority, but it would be good to be able to see it. Therefore, access, I think, is critical.
