Imagine a planet whose inhabitants
Have only two sexes
She says
Imagine a planet whose inhabitants
Oppress themselves

Imagine a planet whose inhabitants
Exploit the weak

On this planet he says
Imagine beings poisoning their oceans

The other species
It says
Imagine this race
Annihilating themselves
Such suicidal stupitity can only be fiction
