(Sep 10, 2020) The success of the Clean Air Act in reducing acid deposition in Adirondack lakes is an under-reported good news story. Many lakes once devoid of life can now support healthy fish populations and other aquatic life. But as Curt Stager discusses with Martha Foley, the life that returns to recolonize the water is not the same as what was lost. Sediment cores show that the original algae and plankton varieties that form the base of the food chain and were unchanged for hundreds of years are being replaced by different varieties. A balance has been restored, but it's a new balance, tipped perhaps by warming, and by invasive species.
