Algae attack

The Chicago Tribune reported today that algae has bloomed out of control on the bottom of Lake Michigan in the past three years, largely due to exotic zebra and quagga mussels. It's sad to hear that the whole native food chain is being altered and that the lake bottom is no longer all boulders and gravel but instead cloaked in algae.
