(Re: "Liberals Should Stop Talking and Start Acting Like a World Leader on the Kyoto Protocol" Embassy Nov. 23) The NDP, and especially Jack Layton, keeps pushing for Kyoto because "it will clean up the air in our cities." That is utter nonsense. Unless all other components, such as oxygen, were removed from our atmosphere, carbon dioxide has not and cannot kill anyone. What can and does kill people are the other things present in our city air such as the particulate matter and industrial pollutants which have no business being there. It is good to inform people, but it is wrong to fill them with misinformation.
