Bolshoi dancers by Mark Andrew Heathcote

I believe the world is changing its core beliefs
it's moving from iron changing into a zinc alloy.
It's now moving from zinc alloys to a mercury core
and what's more, the temperature is rising 
the temperature is rapidly-rising for sure
and potentially, what's more, there is no guarantor.

No promise the Bolshoi dancers shall dance anymore
no, promise that the world will be here at all
to ballet-dance on its axis 
to figure skate like a dying black swan
once, we're all dead and gone.
Once, we’re drowned in the bottom-of-this-mercury pond?
