Letter: Why England is short of water

Sir: Contrary to the impression gained by F Mary Poole, Arizona and the rest of the US South-west make a very bad example of water management. The Colorado is no longer mighty - not only has it been tamed and dammed, with many adverse ecological effects, but it now disappears into the Mexican sands before even reaching the Pacific. The water table has been lowered throughout the region, and Las Vegas is in grave danger of running out of water.

The conspicuous consumption of water in this area, with no thought either for the environment or future generations, is an excellent example for us of how not to do it.
