As John Laurie (Frazer in Dad's Army) would have said: "We're doomed - DOOMED I tell you!"  

It might not be quite that bad, YET!!!  but in my opinion you'd surely be living in a fool's paradise if you did not make at least some contingency plans for the overseeing of an emergency situation.

At it's worst scenario cattle will have to be put down if footrot sets in.  There will be a dire shortage of staple foods such as bread and milk as whole fields, no farms, face massive crop failure where the topsoil is washed away.  The Government will have to step in more and more with subsidies.  It is already happening to potatoes.  That happened not so long ago when half the vegetables just rotted into the ground, and there were barely enough root vegetables to feed the livestock.  **bleep**, stored for winter feed dragged in till April.  Because of crop failure there was a massive bread and sugar shortage.  I kid ye not - this happened in about 1973.  You queued for everything.  If you saw a queue outside the bakers, you'd join it, not knowing what you were queuing for.  It was grim.  My late father and I had to suppliament potatoes for spaghetti - we ended up enjoying it.  Pasta - cheap, easy to cook and versatile.  Start off with pasta of any type.  Cheap as chips and easy to cook - has a very long shelf life.  Follow this up with porridge - you don't need milk - it can be made with hot water, and is substance in an emergency.  Long life milk, put into a cupboard and forgotton about. or better still, condenced milk - one teaspoon whitens and sweetens tea.  Powedered eggs are already disappearing.

Start NOW - DON'T WAIT UNTILTHE ELEVENTH HOUR.  Prophet of doom?  I hope so
