That's a good question. As you know, first of all, we're doing our own analysis of what it would take to operationalize two billion trees. It is incremental, so that would be over and above the existing forest cover that exists in Canada today.
I would say that Canada is a world leader in the sustainable management of our forests. If it happens to be in areas that have been disturbed by wildland fire, or pests such as the mountain pine beetle, for instance, it would qualify as incremental because, in Canada, if you cut a tree, if you harvest a tree, you have to replace it, but not if it's destroyed by insects or by fire. Sixty or 70 years down the road, there may be a harvesting, and by law there would be a renewal of that tree that was cut.
