I have read several articles in The Times about the gas cloud that has killed many people in Cameroon, Africa. That gas, carbon dioxide, has been labeled as "poisonous." I submit to you that carbon dioxide is not poisonous.
When one dies in an atmosphere of high concentration of carbon dioxide, he has not been poisoned by the carbon dioxide; he dies from lack of oxygen, and has suffocated or asphyxiated, just as if he had been strangled, or if he had drowned.
