This gets back to the need to adapt to climate change, which I think my colleague made some comments about. As you go further north, you see a lot of permafrost, but we're already seeing some of that permafrost melt. A lot of our infrastructure, especially in the north, is sensitive to those kinds of changing conditions. The zones where you can grow agricultural crops may change. The kinds of species that you once saw in the south may start moving further north. Again, we know that climate change has a very significant impact.
