Is There an Eco in Here?

I landed at the Ft. Lauderdale airport yesterday and there was a sign that said that to decrease water use, the airport has changed its thermostat from 74 to 78. Call me hopelessly brown, but it seems to me that they can attract more money to pay for more water via tourism if their airport is comfortable rather than politically correct. Water can be recycled, pulled out of the ocean and the air. The economic value of the savings is summarized by the market price for more water which is still measured in hundreds of dollars per acre foot. An acre foot is enough water to cover an acre one foot deep, or 325,851, gallons putting the price of water in gallons per cent. Skimping on use is pain for no gain. Or is masochism the main point of being Green?
