@lowqualityfacts ok, I'll be the boring facts guy here:
the average salinity of sea water is 35g/l
all the oceans combined hold about 1.5 * 10^21 l of water.
that means, the salt dissolved in the oceans is about
5.6E19kg or 56.000.000.000.000.000 tons of salt. That is jst over 11 billion times five million tons.
Take your time, United Nations, we've got a few billion years
The moon weighs about 7.35*10^22 kg which is just about 1300 times the weight of all the salt on earth.
