Water

Turn on the tap
and the water flows.
Does anyone know 
where the water goes?

Turn on the tap
and the water comes
does anyone know
where the water's from?

Water is clean
and water is cool,
living in rivers
and raining in pools.

Yet water can trickle 
and wells can dry up
till there's nothing left
to fill the cup.

Today there is water
when we turn the tap on.
But what will we do 
when the water is gone
