No animal sounds break the stillness.
All creatures were taken, along with humankind, by the same radiation poison that eventually blanketed the globe. Mother Nature is slowly repossessing, with global warming cooling, with coral reefs and forests thriving.
But it is a silent world. A silent planet. Only the sounds of nature persist. Winds whistle and waves crash around and beside empty roads and buildings. Cities crumble with decay. No development, no expansion, no maintenance of what remains. No machines buzz or conveyor belts rattle, no pumps surge, no clocks tick. No servers humming. All digital technology dead. All forms of energy generation long gone. All stored energy depleted. Power stations and processing plants, silent. A dead and decaying world. A barren planet.
Hard to imagine; and not one single living soul remains for the telling of it.
This must be fiction.
