> More capacity => More journeys => More fatalities. Dead people aren't dead "per traveller mile" they're just dead. This is overly simplistic - it’s not useful to quote “number dead” without considering the quantity. By just the “number dead” metric, bull fighting or skydiving would be safer than a game of football. It only really makes sense when you consider (deaths from football / games of football played) vs (deaths from bull fights / number of bull fights) which is when we find that bull fights are actually more dangerous! We could also say the same with surgeries: the more surgeries that are carried out the more deaths by surgery there are, but it doesn’t follow that this means that we should stop doing surgeries.
