The Archivist of Third Chance by Ashley Shelby (novelette)

After a generations-long mass extinction event results in a starving population unaware that animals ever existed, Third Chance Nutrient Solutions’ vertical space farms are growing more than produce. When the company’s Archivist—the only employee in full possession of the history of the demise of Earth’s animal kingdom—discovers the company’s secret plans to rebuild the dead species and restart the cycle of enslavement and pain that caused the extinctions, he will sacrifice everything in order to destroy the project.
