Doh!

Will Greenies never learn? First they were told that DiHydrogen Monoxide was a deadly killer (Water to you and me), now they’re being led to believe that wearing a breathing mask filter will save the planet from their CO2 emissions.

“Every human being exhales about 2.5 pounds of CO2 per day and 7 billion people equals 14 billion(ish) pounds of CO2 daily that is exhaled. So this mask would filter CO2 from your breath. Which is kind of cool, because it would reduce your personal carbon footprint on the earth.”
Would you be willing to wear that for a few hours a day? While you sleep? How about your children? Pets?
Alas, science.

Makes you wonder about the gullibility of some people
