It can all rot

Let the paving and asphalt break up,
Let the lofty spires fall,
Let the timbers rot and girders rust,
Concrete crumble, brick work moulder,
You need do nothing at all -
Just let it be.

Let our world fade from memory,
A bad dream from which the world awoke.

Red and Blue and 3d, too...

An image of depth for those who might see,
'Tis but a tree...
