As bad as this is, in say 50-100 years time, it might be a really horrible issue for mid-western USA....
Things are worse other places.
Australia as a exsample.
Time frame there is even shorter.
The outcome? they will have to stop certain farming sectors that rely on underground water sources, as there's soon to be none.
Also I suspect water prices will rise to the point, that you dont want to "water the grass" outsides.
Food & Water prices going up, as a result of global warming is also a issue.
