Atmosphere needs to stay in balance
Re: Letters – Stop staring at my soft drink, and carbon dioxide is not pollution, Oct. 27.
Letter-writers Colin Alexander and David Wieland asked why carbon dioxide is treated as a pollutant in the fight to protect against extreme climate change.
CO2, water vapor, nitrogen and oxygen are all part of the atmosphere and necessary for life as we know it. But none of us would survive in a room full of CO2, just as we would drown in a room full of water or risk immolation in a room full of oxygen.
