These are choices that governments make about how much to restrict pollution—and you've claimed the $6.4 billion, which we'll accept as a model. When other choices are made to allow pollution to increase, then there are also consequences to those choices. It's curious to me that the government hasn't sought out what the health impacts are of allowing the oil sands to increase by that much.
I have a question about the science, and this might be for Madame Séguin. There was a statement made by Mr. Blagden earlier that there are no direct health impacts associated to greenhouse gas emissions. I'm having a hard time understanding the validity of that statement.
