bike riders have an "increased heart rate and respiration," the act of riding a bike "results in greater emissions of carbon dioxide from the rider."
"Since CO2 is deemed to be a greenhouse gas and a pollutant, bicyclists are actually polluting when they ride,"

yeah...no

Drivers still breathe, make them pay a carbon dioxide tax too.

Do people try to be this stupid or does it just come naturally for them? Ugh.
