Worlds tears and where do they go?

So many peoples tears throughout the world,
if all collected could fill our oceans in just one days fold....
imagine the salt mines if tears were collected,
dried out and crystallized.
what would we use the salt of a whole worlds happiness,
anguish,
joy and pain for?
would we use as an emotional natural drug,
to take is a roulette of feelings or a mixture of all.
imagine the power as peoples thoughts and feelings surge through you,
destroy and kill or all happinesss and love,
all of this from the tears of the world.
would we melt the snow,
sleet and ice in peoples alltogether warm and joyfull tears that some produced.
would each type of tear be seperated,
each one for their own special type of use?
where do our tears go? 
Do they evaporate into the earths atomosphere or soaked back into our skin or clothes or tissue that we dispose of.....
rivers wasted on tissues and thrown away.....
when tears are falling and the sun is shining,
why do no rainbows form?
Do they go up into the clouds?
and rain back down to drench our souls in what was already withdrawn from our living forms?....
we could have different tear pools for different types of mood?
sounds extravagant but when u think how much each of our faces do leak,
where do they go and what do they form?
salt plains is surely the way to go.......
