FORUM Water Pressure If every family of four switches its showers from ten minutes to three minutes, the water savings in North America alone would be on the Great Lakes scale. JEANNE LAMBERT GRAHAM Bishop's Mills, Ontario Perfect green lawns in Vegas? Dancing water fountains at the Bellagio? I am counting on the wisdom of our leaders in Canada to never agree to the bulk export of our water to feed the excess and waste of our neighbors to the south. LYDIA REPLANSKY Ottawa, Ontario I would be eager to reduce my rate of consumption if I could be certain that the water saved would be added to the stream flow to support the natural environment of our watershed. But I know that if I reduce my use, the water I save will be sold to new homes in new subdivi sions at below cost to subsidize population growth. Future pop ulation growth guarantees that our water problems will only get worse. ALBERT ALLEN BARTLETT Boulder, Colorado In Singapore, a nation that has little in the way of natural resources, the government is constantly seeking ways to reduce our dependence on freshwater sources. Desalina tion is a step in the right direc tion. However, your article did not address the root of such rtutn t"K;K problems: Human population may hit nine billion by 2050. No matter how resourceful we are, there will come a time when resources will never be replenished. JEFFREY LOW Singapore Most canal irrigation projects fail farmers in developing countries. Addressing the issue will take more effort than the adoption of the simple devices described. Drip irrigation, however successful in some areas, is not a silver bullet.
