Inspired by this GD thread:
Kix brings up an interesting point:
Is such a thing currently possible? Could we or an adversary (or have we already) engineer a bio-weapon that would introduce a virulent crop blight that could take out all/much of the corn/wheat in the Great Plains? I’m thinking something that could be spread on the sly by spies in a few different areas early in the season, that would then spread and kill the rest.
Granted, we have pretty big-ass surpluses, so even one year’s crop failure wouldn’t mean the death of everyone in the US (though it would obviously strain us and probably necessitate early livestock slaughter for lack of feed), but is such a weapon possible with current technology and expertise?
