Against the backdrop of man-driven deforestation pushing some species to extinction, my world needs a viable basis for the survival and thriving of tigers after an apocalypse. It would seem counter-intuitive given large predators are often the most vulnerable due to large territory needs and a slow reproductive cycle (making it more difficult to pass on the genes for a better chance at desirable adaptations).
In our version of Earth, poaching and deforestation appear to be serious challenges to the survival of the tiger species. However, the thriving of the tigers cannot come at the expense of killing off all humans.
So, instead of all of humanity suddenly died from a lethal human-only virus, or nanobot gray ooze, I want to maximize the amount of humans in this world so that the emphasis is on what needs to happen to tigers to survive in urban environments indefinitely.
The immutable constants:
- No forests left (all of earth's land is a metropolis)
- Tigers have to survive
- Many humans still exist
Basic world summary:
- Concentration of human populations (size of societies): sparse
- Level of technology (must assume there was once modern civilization): answer configurable
- Some level of plant life (can assume there is some plant-life to keep ecosystem going, but don't think giant forests)
I can accept that there are no givens, but I definitely need to maximize the tiger's chances in a post-deforestation world. This means I'll need an evolutionary narrative, including but not limited to: new adaptations, new hunting strategies and other behavioral modifications.
What evolutionary narrative would satisfy the stated requirement of having tigers survive indefinitely in a post-deforestation world?
