Finish the sentence with something that seems like a human innovation no-brainer
For instance, my finish would be:
”...convert salt water to fresh water, economically?”
We’ve had since the beginning of time.
Imagine the consequence when human exploration/travel/transportation was largely by sea.
What if humans were consuming all the fresh water in the Western US?
Wouldn’t it be prudent to get things settled out here on Earth – war, pestilence, and famine wise – before we worry about extraterrestrial exploration?
