If you don't believe me, simply do a Google search of
"carbon dioxide" "poison", and see for yourself...

OK. From that Google search:

http://www-formal.stanford.edu/jmc/progress/co2.html
"Carbon monoxide CO, unlike CO2, is a bad poison. ... Carbon monoxide binds
very strongly to the iron in the hemoglobin in the blood. ... Because carbon
monoxide binds to hemoglobin so strongly, you can be poisoned by carbon
monoxide even at very low concentrations..."

http://www.factmonster.com/ce6/sci/A0810371.html
"It [carbon dioxide] does not burn, and under normal conditions it is
stable, inert and nontoxic. ... Although it [carbon dioxide] is not a
poison, it can cause death by suffocation if inhaled in large amounts."

http://www.prn2.usm.my/mainsite/bull...995/nst13.html
"Chemical asphyxiants - Carbon monoxide, hydrogen, cyanide, nitrites,
hydrogen sulphides. ... Simple asphyxiants are physiolocigal inert. ...
Victims exposed to them will suffer from lack of oxygen. Carbon dioxide and
methane are classic examples of simple asphyxiant. Chemical asphyxiants, on
the other hand, interfere with the body's ability to utilise oxygen, They
either prevent oxygen delivery (such as carbon monoxide and hydrogen
sulphide)..."

There are many others saying that CO is a poison while CO2 is not.
