the co2 in your tank has likely been co2 for millions of years (unless you believe the Earth is 6,000 years old, then by all means, replace the word "millions" with "thousands"). It's one atom of carbon and two atoms of oxygen. Our atmosphere contains co2, and plants live off of it. If co2 spoiled, life on Earth likely would have never existed.

Sometimes when I reflect back on all the beer I drink I feel ashamed.
Then I look into the glass and think about the workers in the brewery
and all of their hopes and dreams. If I didn't drink this beer, they might
be out of work and their dreams would be shattered. Then I say to myself,
"It is better that I drink this beer and let their dreams come true than
be selfish and worry about my liver."
