In 1973 a reportedly drunk driver flattened a tree in the middle of the Sahara, which sounds unremarkable until you learn it was the only tree for 250 miles around, a 300-year-old acacia so isolated it was marked on maps covering half a continent. https://share.google/ePM21R48Aq0VRqTUb
New trees haven’t been able to grow there for centuries. You’d have to spend a century giving the new tree progressively deeper irrigation until the roots reach the current water table, 40+m deep.
Yeah I realize it would require irrigation but that’s very doable with modern technology.
We could fundraise an electric truck to bring the water or something.
Would need a pretty good fence around it. Sounds like unaware and drunk drivers are great at hitting the only thing around for miles.
