If it is true that there is enough fuel in the full fuel tank of a jumbo jet to drive the average car four times around the world (hat-tip to 20 Mind Blowing Facts You Probably Didn’t Know) I wonder which has more impact on the environment -- driving or flying.
It seems to be a toss-up.
The distance from here to Durban is 600 km, which we could just about make on a tank of fuel. So if 300 people drove to Durban they would travel 180000 km. Four times round the world is 160300 km so for 300 people on a jumbo jet that is about 535 km, so that seems better than going by car.
But that assumes one person, one car. So if there are three people in a car, it would tip the scales in favour of the car.
But then a jumbo jet wouldn't use a full tank of fuel to go to Durban.
Oh, I give up.
