    I've thought for a while that it would be interesting to have micro dehumidifiers on my roof that supplement my water supply from humidity.

    Turn myself into a moisture farmer if you will.

    But then I wonder, would it be a problem if everyone did it? Would it cause humidity to drop in a bad way?

      In humid regions, there is no practical limit that would cause any noticeable effects on the humidity of outdoor air. There is just so much water in the air that even if you were running dehumidifiers across all available land area, the air is still going to feel humid.

        True but in those areas it also tends to rain a lot so it's less necessary. I'm thinking about Mediterranean and desert climates.

          As long as the water is being locally used and locally discharged (i.e. via a drainage field) it shouldn't seriously have an impact. The water would return to the water table and either be used by plants or get wicked back into the air via capillary action from evaporation on the surface.

            I guess technically you’d be adding water to the water table since the water was in the air before you pulled it out.
