FFVII-Life
Explain please.
As I reckon the Theme is Painfully clear throughout the game, Shinra's Midgar being the best example of Technology taking over nature. The ending of Midgar getting destroyed and hundreds of years later nature started growing where Midgar once was should be seen as relevant.
Remember the whole planet is crying stuff? Bugenhagens whole planet thing? Thats definitely the theme, not Life. Life is FFIX, I mean Every character has a theme towards Life.
