Great Lakes near ecological breakdown: scientists
Thu Dec 8, 2005 2:16 PM ET



By Andrew Stern

CHICAGO (Reuters) - Stresses from polluted rivers to invasive species threaten to trigger an ecological breakdown in the Great Lakes, a group of scientists hoping to sway U.S. environmental policy said on Thursday.

Seventy-five scientists who study the world's largest collective body of fresh water released their report on the myriad problems that need cleanup or restoration ahead of two key policy announcements next week.

"This is just a critical period for the Great Lakes," Andy Buchsbaum, director of the National Wildlife Federation's Great Lakes office, said about next week's announcements.

A task force comprising federal agencies, Congress, local government officials and regional Indian tribes is scheduled to release its much-anticipated final plan for preserving the Great Lakes requested by U.S. President George W. Bush in 2004.

The body's preliminary report in July recommended $20 billion in federal, state and private funding over 15 years to upgrade antiquated municipal sewer systems, restore 500,000 acres of wetlands, clean polluted harbors and bays, and pay for other efforts.

But a federal oversight group subsequently suggested to the White House that the budget was too tight to allow additional funding. Federal spending on Great Lakes cleanup over the past decade was $800 million, according to the Government Accountability Office.

After the task force releases its plan on Monday, governors representing U.S. states and Canadian provinces that border the Great Lakes will announce revisions to century-old rules that restrict water withdrawals and diversions from the lakes. More than 30 million people rely on the Great Lakes for drinking water, and large-scale diversions to far-off states or countries have been forbidden.

Threats to the Great Lakes are converging, scientists who worked on the report said.

"There's widespread agreement that the Great Lakes are under tremendous stress," said Alfred Beeton of the University of Michigan. "Toxic substances ... overfishing, invasive species, changes in hydrology affecting rivers -- now we can add the effects of global climate change.

"These have been dealt with individually. What we need to do is look at the ecosystem -- the combination of stresses," Beeton said. "Historical sources of stress have combined with new ones and we have arrived at a tipping point. What we mean is that ecosystem changes will occur rapidly and unexpectedly."

The report emphasized the need for large-scale ecosystem restoration and not piecemeal efforts, coauthor Don Scavia said. Particularly important was preserving or restoring shoreline "buffer zones," such as wetlands and lake tributaries to help the lakes heal themselves.

"These are the key areas for filtering the contaminants that enter the lakes. It's also where most of the wildlife habitat is," Scavia said.

Shoreline pollution that fouls Great Lakes beaches is extending into the middle of some of the five Great Lakes, sudden drops in oxygen levels in the water threaten native species, and native fish have been crowded out by invasive species that have changed the character of the lakes, the scientists added.

Not sure of the polution issues but i do know of the invasdive fish species.The asian and silver carp are threatneing lake michigan natural balance as well as many of its offshoot industries such as fishing. Its gotten so bad that they are actualyl meetign to discuss the issueand hwo to stop it. They have started electrifying the canals tha t connec t the missisippi tot he lake butt hats ntoteh best solution as it allows the carp in roe form to sneak through. Yet anothe r possible solution is to create dead zones....areas without any oxygen which will basically make the wildlife in these areas die and create a death border betweent eh uneffected and effected areas.
 
My original hometown, where my mother still lives, is very close to Lake Michigan. A few years back it was at the lowest level I have ever seen it, but then the subsequent years it went back to normal. I'm certainly no expert on the subject, but last time I was at the lake this summer it sure seemed like the same old lake I used to spend my childhood in. I don't fish, so I can't comment on that. Where I'm from, which scarily enough is the area where Syntaxx-Wrath is *shudder*, the water is beautiful and you certainly can't tell if it's polluted.
 
Let me put it to you this way. I see alot of signs to not eat the fish. Has to make you think. I mean would you pee in your milk and drink it? Then why dump in our lakes? Us as humans have a major issue of living within our environment. Instead we destroy it and not live within balance. Now do I mean go be a tree hugger? No but I mean we have to as a collective species watch what we do and the effect it has on the whole.

Thats why ive always agreed with the qoute in the Matrix, that Human Beings are more classified as a virus then a mammel
 
I wouldn't go that far. After all, with the same brain power, opposable thumbs, and stature any other mammal might do the exact same things we're doing.

But a higher level of being should be smarter. If everyone jumps off the bridge don't make it the right thing to do.
