He says 
Imagine a planet whose inhabitants 
Have only two sexes
She says 
Imagine a planet whose inhabitants 
Oppress themselves
It says 
Imagine a planet whose inhabitants 
Exploit the weak

They look at the stars and laugh

On this planet he says
Imagine beings poisoning their oceans
She says 
Imagine these beings destroying their environment
It says 
Imagine these beings polluting their air

They shake their heads and think how funny

On this world he says
Imagine a race who say 
They're the most intelligent
She says 
Imagine this race annihilating 
The other species
It says 
Imagine this race 
Annihilating themselves

Such suicidal stupidity can only be fiction 
They finally say
