Theory from my friend lemme know what y'all think

lily had Gaia fruit and used it to seperate road poneglyph and Alabasta used to be green before due to Gaia fruit of lilly but after her death it became deserted Cuz the earth lost her goddess Gaia because Gaia is the personification of the earth itself, often acting as a nurse to creatures and a provider of crops, not a desolate, arid force.
