Mr. Speaker, it is presentations like the one the hon. member just made that reduce the credibility of this whole argument.
This debate is about lowering the emission of greenhouse gases. Those greenhouse gases would include mainly water vapour, carbon dioxide and some other much more minor things. When members wander off and talk about water and air pollution, smog in cities and all the rest of it, it takes away from the credibility of this argument. As a matter of fact, the greenhouse industry in Canada pumps carbon dioxide into greenhouses because it makes plants grow much better.
Could the member opposite focus on the issue we are debating, which is the reduction of greenhouse gases?
