In the Great Lakes, freighters that altered the isolated waters injected nonnative species into the lakes. These species include alewives, sea lampreys, and zebra mussels, which have ruined food webs.
Another issue, toxic runoff and algae blooms causing fluctuations in the water have been attributed to climate change. But, the native white fish and trout are repopulation and gaining control of balancing many food webs.
This issue is yet another indication of how human actions have an affect on ecosystems. Invasive species easily have populations that can boom out of control, and yet it could be easily prevented.
