So Magical Energy can come either from within (Ki) or from the environment (Mana), and has no particular trait in its natural state, but is rather a potential that takes form via bonding with a catalyst, most famously natural elements thus giving birth to elemental magic ?

And large-scale spells are fuled by the Ki present in the atmosphere, and thus compromised or even nullified by atmospheric interferences ? Seems like high-level Air mages/espers would have major advantage against most magic-reliant opponents, as they could radically impair their foes' magical abilities while channeling massive amount of mana from the atmosphere to power their own spells.

Last but not least, since most magical energy is processed Ki and Ki is an etheral natural resource, wouldn't large-scale spells cause heavy environmental damage independently from their specific nature, since they inevitably deplete large quantities of Ki in the surrounding area, which explicitely takes a lot of time to replenish ? Magical Energy sounds like a fantastic counterpart of real-life oil and industrialization somehow, with great power and prosperity directly fueled by environmental destruction, making it a relatively short-lived and exponentially self-destructive path on the long run.

In short, how does Destiny City and the world at large handle the global resource management of Ki ?
