People need water. Plants need water. Fish need water. Wildlife needs water.
It doesn’t always fall from the sky, let alone when you want it to and in the right quantity.

Billions of people are going to leave a mark. We should tread as lightly as we can, but acknowledge that we are supported by infrastructure that is out of sight and out of mind.
