I'm guessing that man leaning on a tree hasn't been downwind of a cattle farm.phinds said:
A quick Google check shows that there are 1.4 billion cars and 1 billion cows. Assuming that a car is parked (and turned off) for 95% of its life, that amounts to 72 minutes of running time per day. Meanwhile, the cows are happily producing 'emissions' 24/7. Even if you were to compare an average of cows to cars (1B cows/1.4B cars), it would still work out to 17 hours of cow emissions per day as compared to a car's 72 minutes.
