Picking up on something that Alec wrote about flooding and now being not a good time to be in insurance, I always think that the Monster Raving Loony Party had the right idea in their 2001 UK election manifesto.
Under a Loony government any prospective home purchaser be issued with a full description of such dictionary terms as ‘floodplain’, ‘coastal erosion’ and ‘exposed headland’. This will save time explaining why they have no house anymore after nature takes charge of the environment. In addition to this policy, building on floodplains in future will be restricted to large houseboats with recoiling tethers like dog leads. These houses will be able to float up with the floodwater and land safely again in the same place when the water subsides.
