Answer:
This story is set in a future where anything can be done using technology.
Step-by-step explanation:
In my opinion, we are fast approaching an era of driverless, internet-powered cars, homes that can be printed from a 3d printer, fully automated banking, AI Judges e.t.c.
Robots are already taking over human jobs. Those (robots) that have been infused with Artificial Intelligence are currently being tested for commercialization.
When robots are commercialized, they will change the face of how things are done around the globe permanently.
As for trees, there are no commercial plantations anywhere in the world that can satisfy 30% of the worlds demand for wood/coal. This means that deforestation is not yet a thing of the past. Its consequences are looming.
Cheers!
