Sometimes we are truly thankful for each day we manage to stay on top of the ground. If we lived a few thousand years ago, in or near the desert, we might prefer to get out of the hot sun by working underground. Digging tunnels that carried water from place to place would be like working in air conditioned comfort. Now the ancient me is thinking: “The longer I make the tunnel, the longer this cushy job will last!
Conserving water is one thing we’re forced to think about during a drought. And, sometimes it helps to consider the extremes when we’re searching for sustainable solutions. For example, there are golf courses on the Arabian Desert where the sprinkler system uses several times the usual amount of water, so that at least some of it will hit the ground before it evaporates. Yet, in ancient Ninevah and Babylon, there were pockets of innovation that produced aqueducts, various water elevators, and the earliest examples of that water culture we’ve come to know as hydroponics.
