Thanks to the official secrecy act, this story is only now coming to light, but I think it is possibly the greatest (for being the most bizarre) news story I have read in a while:
BBC NEWS | UK | Nuclear threat sparked tea worry
"The threat of a nuclear attack on the UK in the 1950s caused concern over the supply of tea, top-secret documents which have now been released reveal.
Government officials planning food supplies said the tea situation would be "very serious" after a nuclear war.
"It would be wrong to consider that even 1oz per head per week could be ensured," they stated.
The papers were released under the Freedom of Information Act by the National Archives at Kew.
Heart and health
The documents said a nuclear conflict would result in the loss of three-quarters of tea stocks."
It goes on but this is the best part of it. I mean, here I was worried that nuclear war would kill, say three-quarters of the world's population and that it would poison our crops, give us radiation sickness, bring on nuclear winter etc. But clearly I had my priorities all wrong. Little did I realise the effect it would have on tea stocks and supplies! Thank god it never broke out

cause I was totally unprepared for that "very serious" tea situation.
