Not optimization of a computer algorithm about the water cycle... Optimization of the physical water cycle itself…! That sounds weird, doesn't it? It's painful to observe most human interventions on earth have resulted in some destruction in the ecosystem. It's hard to say we have contributed to its rejuvenation. Can the proposal presented below serve the restoration of the "default climate behavior" of the earth while having no side effects or negligible, compared to scary risks awaiting us? I have an idea and I need to discuss it with experts of the broader topic. Any insight shared has a potential to affect the direction of our research on natural cooling techniques. An Example Case Let's start with a photograph which is absolutely fa sc in at in g . It is an aerial image from part of the Amazon jungle. It shows formation of clouds on the rainforest as a result of evapotranspiration. The original
