Permanent Drought and Water Efficiency

The dried-out forests of South Lake Tahoe are ablaze today with hundreds of homes destroyed and hundreds more in danger. Meantime, a historically Western problem is moving East. Grass that used to be underwater caused massive fires last month in Florida's Lake Okeechobee; there's drought in about one-third of the country, including 40% of Alaska and parts on Minnesota. However, not all water shortages are caused by Mother Nature. With drought increasingly a fact of life, we talk about shortages caused by the way we use water. Are water restrictions and higher prices in store?
