How Many Poem by Mark Heathcote

If a stone sinks,
From where was it raised?
If the salts in the sea
Came from you and me
How many grains of sand once were we?
How many bees
Did it take, to pollinate these giant redwood trees?
How many crushed chirping cicada insects once were we?
How many weeds and undeveloped sapling seeds were we?
"So they've had their moments and graced the sun".
I guess those whose waves, had to roll-undone
Have been left to leave but few or none:
There in any case of firing a starting pistol gun.
