Mr. Samis, you talked about the need to regulate fine particulate matter. Within the fossil fuel range, of course, there are differences in the fuels you use. There's been much research done on the impact of diesel fuel, with its fine particulate, as a special hazard to human health, be it to heart and lungs or be it because of carcinogens. So don't we have to be very careful when we're speaking about fossil fuels as well in order to understand their impact, in terms of their relative merits, on human health? Simply by lumping them together, we're doing a disservice to our understanding of how to deal with them.
