[MCN] EPA waterways protection rule has scientific basis

[Lance Olsen]

Recent news reports cite environmentalists' support of the recent EPA 
rules on water protection in the United States. True enough, but 
reference to environmentalists' support ducks the issue of 
scientists' own support of better protection for the waters of the 
United States.

Among the world's scientific journals, Science is in the top echelon. 
I have the pdf of a Science article, written by scientists, for 
scientists, on the importance of water protection like that now 
proposed in the new EPA rules.

If you'd like to see that article for yourself, just send me a note 
off-list, at lance at wildrockies.org

"Localized ecological systems are known to shift abruptly and 
irreversibly from one state to another when they are forced across 
critical thresholds. Here we review evidence that the global 
ecosystem as a whole can react in the same way and is approaching a 
planetary-scale critical transition as a result of human influence."
