Once again, shit could defeat philosophy, learning and politics.
Norwich town hall - where Norwich Council carries out it’s cerebral machinations and deliberations is under attack from pigeon shit.

They are afraid and according to this story, are planning to install wires and posts to prevent the birds from depositing their guano.
Pigeon shit is highly corrosive, especially against the flimsy sandstone that Norwich selected to build its tower of power.
Perhaps next time they will think of something like granite or glass which can take the shit better.
Then again, shit lasts for ever and will prbably secure the final victory to be around long after the human race has disappeared up its own palooka.
