CO2 is not, and has never been, a poison.

HERE

István Markó: Again, CO2 is not, and has never been, a poison. Each of our exhalations, each of our breaths, emits an astronomical quantity of CO2 proportionate to that in the atmosphere (some >40,000 ppm); and it is very clear that the air we expire does not kill anyone standing in front of us. What must be understood, besides, is that CO2 is the elementary food of plants. Without CO2 there would be no plants, and without plants there would be no oxygen and therefore no humans. The equation is as simple as that.
