After East Asia & Pacific on the rise blogger and World Bank conservationist Tony Whitten recently questioned the morality  of jetting off to Asia so often for work, this chart  from GOOD Magazine  – comparing (sort of) the efficiency of different modes of transportation – caught my eye.
Since the people who made the chart are considering gallons of fuel used per passenger to travel a long distance, Tony’s frequently used airplanes are far from being the worst offenders on the list, which is led by gas-guzzling SUVs and cruise ships. When it comes to realistically traveling 350 miles, your most efficient choices – in the following order, according to this chart – are to travel by bus, train, or (you guessed it) airplane.
If that doesn't cut it for you, however, and you are feeling particularly energetic, they made a conversion to human energy. In such a case, GOOD estimates, a person would have to consume approximately 16 Whoppers  to complete the trip by bike and 48 of the mouth-watering cheeseburgers to trek the distance on foot (To be safe, I'll take a similar stance as GOOD in "neither endorsing or denouncing the consumption of Whoppers").
As an aside, I would have liked to figure out how many of the burgers it would take to fuel the number of air miles logged by World Bank Group's Washington, DC, staff (as Tony discovered , it equals at least 400 million miles each year) – were they to travel by foot. But seeing as my math skills were never too great, maybe one of you, dear readers, can help me figure out their equation?
