He doesn't mention pandemics

Let us unite, 

let us hold each other tightly, 

let us merge our hearts, 

let us create — 

so long as the warmth of this earth endures, 

so long as no earthquakes, cataclysms, 

icebergs or comets come to destroy us — 

let us create for Earth a brain and a heart, 

let us give a human meaning to the superhuman struggle.
