In terms of greenhouse gas and acidification.... In our mining project, obviously, we don't see acidification as a big impact.
Your previous comment on drought and climate change is very interesting in that one of the key components of our regulatory review is the impact of climate change on our project. Echoing some of the other comments, we will need to look at not only drought but also increased precipitation—rainfall and snow, of course. I've been up in Yukon. A key change I've seen over my career is that this is an important part of what will be reviewed as we go through the regulatory process.
