Literally. It’s done with fishing line in wet winter air.
We can send rovers to Mars to find water and life, and we can figure out how to harvest water from a bunch of fishing line, so that we can restore our wetlands to the environmentally productive state we now need. In the past, we used this tech to deter deer from non-native hydrangeas, which, as you can see, are even hanging on.
Now is now. Now is time to step out of the practice ring for the big game.
We can do this. This is not a desert. Yet.
