Question

Quizplus · Accepted Answer

Zebra mussels are an invasive exotic species that clog water intake pipes at factories, power plants, and wastewater treatment facilities. They were introduced to North America in the 1980s and have since spread to many waterways beyond the Great Lakes and Hudson River. While they do excrete waste that can contribute to eutrophication, this is not their most significant impact.
