If you could, you would see deserted streets, buildings, and whole towns.  Cars stopped and rusting along unused roads.  Nature was reclaiming the world, one that got a science lesson.

Regardless of your religious beliefs, the lesson proved evolution to be true in the worst possible way.  One country developed a genetic weapon that targeted a certain group, one prevalent in a specific part of the world. It turned out to be a gene/chromosome group all humans shared — evolutionarily-speaking.  It turned out to be inescapable.

It's not a dystopian nightmare when there is no one to dream about it.
