it is also a fraction of golf courses which you again ignore. this is just typical "don't do anything!!" ism. there's no argument here.. even if data centres used .00001 millilitre of water you would say the same thing.
But (as I pointed out elsewhere in this discussion [0]) why should I have to mention everything that uses water in a way I think is detrimental in order to be allowed to talk about why I think this thing uses water in a way that is detrimental?
your logic will extend to just doing nothing at all because it will take resources from other things that you value.
Of course making the world a better place for everyone is very against western and American exceptionalism and freedom.
