Although it has taken just 60 years for humans to put many freshwater lakes on the eutrophication fast track, a new study shows their recovery may take a thousand years under the best of circumstances.
Writing in todays (June 13) online edition of the Proceedings of the National Academy of Sciences (PNAS), University of Wisconsin-Madison limnologist Stephen R. Carpenter reported results of a study that showed that the buildup of phosphorus in soils in lake watersheds is likely to be the source of serious chronic environmental problems for hundreds of years.
"If these results are correct, and I suspect that they are, things could get considerably worse," says Carpenter, a UW-Madison professor of zoology and one of the worlds leading authorities on freshwater lakes. "The buildup of phosphorus in watersheds is very threatening. Sooner or later it is going to hit the lakes and it is going to pose problems."
