Well, the period from the death of Earth to its reterraforming by humanity's space-born, genetically-engineered descendants is approximately one thousand years.
So far, we're perfectly on track for that. The spread of antibiotic resistance, the early vaccine resistance, the growing environmental disaster, and the growing instability of nations in areas we can't talk about here is all perfectly on track.
All we need now is the widespread adoption of alternative energy, but with shortcuts taken to get the costs down and production up, and a city-wide experiment with hydrogen fuel cells to cement the growing disaster.
I hope you enjoyed the Golden Age of human civilization. It's all downhill from here.
