There might be some value to digging large canals to be filled with ocean water. Without using energy to desalinate, a new body of water in the middle of a desert could cause the dry air to begin evaporating the water, which effectively desalinates it. Then the rain clouds could redistribute the unsalted water to the surrounding dry land.

Of course there’s the issue that researchers say rain water all over the earth now has harmful chemicals. I guess we’ll have to make due as best we can while cutting down on actual pollution, and while ignoring the whole global warming CO2 hoax.
