Ecologists from the University of Michigan say invasive zebra and quagga mussels are causing dramatic changes to the ecosystems in northern Lake Michigan and Lake Huron. Their report says action must come soon to stop the spread of the mussels in the Great Lakes.
Donald Scavia is the Director of the University of Michigan Graham Environmental Sustainability Institute. He's one of the authors of a new report that says the changes are happening quickly and require more attention than they are getting now:
“Our management strategies need to be able to be reviewed and modified every couple of years rather than every couple of decades.”
Scavia said the zebra mussels make it difficult to predict the conditions of the Great Lakes from year to year.
