facing our Great Lakes?
But if I could magically fix just one thing, I would eradicate the invasive mussels in our great lakes. Specifically, the quagga mussels (in photos) that have so completely colonized four of the lakes and are eroding the foundation of the food web.
THIS ARTICLE gives more details about how the quaggas have thrived in our Great Lakes. It is estimated that there are over 400 TRILLION quaggas in Lake Michigan alone.
From the article:
The havoc they have created includes an increase in toxic algae, a loss of tiny plants and animals that fish feed on, a decline in prey fish, and skinnier game and commercial fish.
But they represent a lesson for the future.
Of the 186 invasive species in the Great Lakes, two-thirds came from ships in the St. Lawrence Seaway, which pick up ballast water in foreign ports and discharge it into the Great Lakes. "We need to cut off the tap," said Kerfoot.
