Water has an economic value in all its competing uses and should be recognized as an economic good
The Dublin Statement on Water and Economic Development

In a warming world, will people fight over dwindling water supplies?  Will there be water wars?  What has economics to teach us about this?  As glaciers recede, as lakes and rivers dry up, what then of the laws of supply and demand?  What then of property rights and the free ride principle^*?

The War Of The Wells

Anti-smoking activists have made some ridiculous claims about smoking and the associated health risks. In recent years, studies have suggested that movies encourage teenagers to pick up the habit, any exposure to secondhand smoke is dangerous, and that such a thing as ‘third hand smoke’ exists. But a new study in Environmental Health may be the greatest example of exaggeration on the issue ever.

A new report from the National Research Council suggests that naturally occurring methane hydrate may represent an enormous source of methane, the main component of natural gas, and could ultimately augment conventional natural gas supplies. Although a number of challenges require attention before commercial production can be realized, no technical challenges have been identified as insurmountable.

Moreover, the U.S. Department of Energy's Methane Hydrate Research and Development Program has made considerable progress in the past five years toward understanding and developing methane hydrate as a possible energy resource, the report claims.
