I don’t have time to read the article, but it occurs to the Pope needs to review his basic sciences. Last time I checked, CO2 is necessary for plant life and our lungs are destined to exhale it. If he doesn’t understand it’s a bad idea to rework God's creation, maybe he’ll respond to, “It’s not nice to mess with Mother Nature?”
It goes without saying that carbonated beverages will be banned from Vatican City and all religious will take a vow to abstain from their consumption. For those who wish to make great spiritual progress in the new religion, burping, farting, coughing, sneezing, and nose-blowing are to be eliminated. The Pope and his Cardinals illumine the way ahead by abstaining from exhaling altogether.
