The potential disaster would occur if alien invasive species of fish were to cross from the canal into Lake Michigan.
I also plan to write at least one Environmental Graffiti article at some point, with a focus on the invasive species rather than the canal.
As always, I also publicized this article in my DeHaan Services blog; today's entry is "Will a Blockade Prevent an Ecological Disaster?".
First, use an eye-catching image to publicize your articles. Admittedly, I chose another picture to lead the Suite 101 article, because potential readers at that site might make the connection more quickly.
Second, plan for multiple articles based on a single unit of research. It saves time and gives a greater reward.
Just be absolutely sure to change the focus for each article; do not plagiarize yourself.
