Well, for example, we measure water quality across the country, and we measure air quality, the emissions in a variety of constructs, looking for what particles might be in the atmosphere. We also monitor the numbers of species, numbers of caribou, whatever it might be.
We monitor all facets of water, air, and biodiversity. In a number of circumstances, we do it in conjunction with the provinces, and there might even be funding going back and forth, but yes, we're pretty much in all areas of monitoring. There are some areas of special concern. Oil sands was an area we talked about earlier, and the Great Lakes, other lakes.
