See You at the End of the World

The sea-green wall
Of life will end.
We’re sure it will.
Each salt wave breaks;

All the foam sinks
In sand and dries
To leave bleached wrack
That falls to bits,

So the whole sea,
The whole green wall
Will fall and fade
To rocks and shells.

I don’t think so.
Oh, it will go,
But it won’t end.
Prove me wrong, then.
