Jalima - agreed. But the level of rainfall is still the lowest recorded since records began. It’s just not sensible to direct limited resources away from athings we know will be needed to things we think are extremely unlikely to happen.
Meg - entirely logical. I was clearly referring to hugely unlikely natural disasters. As to the potential for an outbreak of ebola, I would say that we have recognised for some time that with international transport easily available, large populations, and the ever increasing risk of localised epidemics of a verity of diseases, the prospect of a pandemic is significant - so expenditure on preparing to combat that risk is money well spent. But I don’t think, for example, that we should spend UK tax money to prepare for the possibility of a drought of proportions exceeding those of any on record. That may happen - but if we have any spare money there are many other things we need to spend it on before we get to that one.
