Response to Gary Kump on carbon dioxide.

Carbon dioxide is not a toxic; you are correct. However, as it increases, it takes up more and more space in the atmosphere. In doing so, it displaces oxygen and other components of the air we breathe. Oxygen then becomes less than the 20.9% humans need.

I’m not sure how much less oxygen we can manage to live with, but I have seen people with COPD (Chronic Obstructive Pulmonary Disease) gasping for air. I would not like to see it become the norm.

Carbon dioxide may not be toxic per se, but its increase can still be hazardous.
