There’s a fairly annoying radio advertisement doing the rounds at the moment, in which two cars talk to each other. One is a bit of a wide boy, and the other is a responsible car that informs the other that cars are humans “third biggest source of CO2 emissions”.
Which leads me to wonder: if cars are the third biggest source of human CO2 emissions, what is at number one and two? My suggestions are (1) things required to sustain humans (e.g. cooking food, boiling water to drink tea); and (2) farting (if that’s the case for cows, then…).
What do you think?
