heh - I'm going to go out on a limb and guess that it takes more vehicle volume to move 35 billion tons of feathers. As Vehicle volume is correlated to vehicle weight, moving feathers will be more expensive :P but in all seriousness, the correspondence to rocks is beneficial as it's not obvious just how much mass industry moves in 2023. If you add in waste rock at quarries the numbers rise precipitously. A single shovel bucket can move 20 tons.
