"The worst crisis of all time, in my view, is the critical global shortage of fresh water," says " Larry Edelson. In Money & Markets, the resource expert offers four water sector plays.

"The world's water crisis is now getting worse by the day. And the global financial and credit crisis is merely one reason why. Another is the ongoing modernization of major parts of the world, which is increasing demand for water, while at the same time polluting it.

"Yet another is major droughts around the world, including in our own back yard, where 60% of the U.S. is officially experiencing a drought.

"New technologies and techniques for better water supply management and improved conservation on the demand side could potentially avert a worldwide disaster. And as a long-term investment, water is one of my favorites. For both its tremendous social cause as well as its profit potential.

"Aqua's first quarter results were by no means a disaster. But they lagged both last year's total and Wall Street estimates.

"Management blamed the slowing economy's impact on housing starts in what had been fast-growing systems, rising bad debt, lower commercial sales, delays in fully digesting acquisitions in the South and longer-than-expected timetables needed to win rate increases.
