Give an example of how an invasive species can cause ecological or economic harm
What will be an ideal response?
Lacking predators, parasites, and/or competitors in their new environment, invasive species can proliferate and dominate a community. Impacts of invasive species have become more extensive in recent years because of the increased mobility of humans and globalization. An example of an invasive species is the zebra mussel. As adults, zebra mussels can attach to boats and ships (they were carried to the Great Lakes on ships). In their new environment, they did not encounter the predators, competitors, and parasites that limited their population growth in Asia and Europe. Their population grew, and they spread to other areas. They clog up water intake pipes at factories, power plants, and municipal water supplies and wastewater treatment facilities. They damage boat engines, degrade docks, foul fishing gear, and sink buoys. It is estimated that they cost the U.S. economy hundreds of millions of dollars a year.
