    "author": "Hans Segura",
    "description": "Nearly half the rain that falls on the Amazon has already fallen there before. Hans Segura follows a water molecule through evaporation, transport, and towering afternoon storms to show how the forest recycles its own rainfall. This short explains why that self-watering loop makes the Amazon both resilient and fragile, and what deforestation does to the engine that keeps it wet.",

This loop sustains the wet season and buffers droughts, but it also means forest loss reduces rainfall over the remaining forest, pushing parts of the basin toward a drier, more flammable state."
