RE: E-M:/ Now Eagles

Just a quick note.  The main reason for bald eagle reproductive failures along GL shorelines has been the accumulation of PCBs in the birds over time. This is not at all a new phenomenon and in some areas, is improving.  Short of issuing fish consumption advisories for eagles, I am not sure what we can do to get the remaining PCBs out of the lake, land, etc. The biggest lesson here is that prevention is the best solution.  About 85% of the PCBs that have entered the environment remain there and cycle through the food chain.  Another lesson is that knowing how PCBs affect eagles, we need to look at our own fish consumption/standards and ensure that the GL have uniform standards.  That's probably a good issue to bring to the Task Force.

In regards to Jack Smiley's comment about bald eagle reproductive failures along the Great Lakes. 

This is a very important issue that ought to be brought up to the Senate Task Force for the Great Lakes.  This task force is taking people's testimony in regards to how we would like to see our Lakes protected.  They have been holding citizen's hearings all across the state recently.  Bob Wilson is the Policy Advisor (and the one who was taking all the notes at our public hearing here in MArquette) for this task force and would be able to pass along your comments to the Senators.  I urge you to write him with these concerns (he's heard enough from me lately).

Thanks, Natasha Lapinski
