Where Most Prepping Falls Short:

[NorthernRaider]

Though our population has risen in excess of 20 million since the end of WW2 when we struggled to feed our people today we have far more advanced agricultural systems and much more productive land, BUT (always a but isn't there?) Modern agriculture is utterly reliant on chemical fertilisers and pesticides made from oil, the plant and agricultural equipment is utterly reliant on oil products.

Our WAR reserves of fuel will support the MILITARY for nearly 90 days but that same fuel if redirected to the entire nations food production industry would only last a week or two.

God knows which horrible scenario is likely to come to pass, the best we can do is try and use as broad a brush as possible with our preps.
