Thanks for your answer! I feel like that makes sense on a global scale, but mightn’t local and regional scales be more impacted? We already know that the transpiration from forests affects rain patterns, and the forests don’t need to be huge either.

Also, some ecosystems might be particularly vulnerable. For example, redwood trees actually absorb most of their water through their leaves from fog and mist. Could a local humidity harvesting plant potentially pull enough water from the air that the osmotic pressure is reduced below what redwoods need to absorb water? I suspect the answer is actually no for this particular examole, but my point is that powerful technologies like these must be thought through, especially if someone is claiming zero side effects. The time is long past for humanity to learn a little caution with potential climate changing technologies.
