As the Rio+20 Agenda unfolds, an image of contrasts comes to mind, that of fire which brought about the so-called Arab Spring and of the majority (of nations) who are frozen and stuck in the Winter of Rio. Robert Frost describes the contrast nicely in his Fire and Ice
Some say the world will end in fire
Some say in ice.
From what I’ve tasted of desire
I hold with those who favour fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
