I guess to be a bit more precise, one of the things we see, for example, in water quality monitoring...we know we're having an impact with some of the programs we're doing, but all the time we're moving along, activity is taking place. We're always trying to measure against what would happen if we were to do nothing. We would see activity increasing, and there might be more nutrients going into the water. Our actions can reduce that, and we're seeing that effect.
I would still caution against an overly simple view of the world that said it's not having an impact. We know things are going on out there, and we are trying to do a better job of monitoring. We're seeing some areas of improvement, but we are also seeing some areas where activity is increasing, and we know we need to put further efforts.... For example, in the area of algae, we know....
So despite some of the things we're doing, we would like to see more improvement.
