Planet Fanfic Suggestion

What so many love
In dystopias
Of the post-plague kinds,

Post-holocaust kinds,
Is the elbow room,
The world to yourself.

Less pleasant are those
Apocalypses
Where Earth’s a prison

Some dictator built,
Some all-powerful
One-party world state,

No buildings at all,
No feral nature,
Just hordes of humans

Like Australian mice
Pouring from a barn
They’ve emptied of grain,

A tide of squirming
Life turned cannibal
That can’t stop eating.

Are there few of you
And plenty of food?
That would be Eden,

No matter how hard
All the gardening.
Mobbed masses of you

Crawling all over
Each other for food?
Not a bestseller.
