The average human exhales about 2.3 pounds of carbon dioxide on an average day. (The exact quantity depends on your activity level—a person engaged in vigorous exercise produces up to eight times as much CO2 as his sedentary brethren.)
~7,000,000,000 human beings X 2.3lbs. = 16.1 billion or ~ 8million Tons of CO2 emitted by humans every day.
We are actually made of carbon. Oddly, the atomic number for carbon is 666.
Is 666 the atomic number? I thought it was just 6, which is the number of protons, neutrons and electrons.
