Peregrine and Eagles Today

January 15, 2018

The Dynamic Great Lakes Blog

A peregrine falcon hovers

Over rolling Lake Michigan waves

Waves that carry something

the falcon is interested in

as it hangs steady in the wind.

On the sandy shore two eagles

Pick up carrion—dead white fish with silver fins.

It’s good to see a peregrine and eagles

Along the lakeshore today.

I thank my good man

For making it that way.

–Barbara Spring

Norm Spring won the Michigan Environmental Hall of Fame Award for his work in banning DDT and thereby bringing back the American Bald Eagle and the peregrine falcon to the shore of the Great Lakes.????????????????

Praise for The Dynamic Great Lakes


In her cautionary book, environmental activist and professor Spring enthusiastically explores the Great Lakes, and clearly explains why they should be protected. —Book Sense Nov 22 2003


This is intriguing stuff for adults, but the straightforward presentation also lends itself to use in schools. —Peter Wild U.S. Water News


Every library should have this book. —Stan Lievense, retired fish biologist MDNR


Worth reading if for no other reason than that the writing is masterfully done…reminded me a little of Rachel Carson’s Silent Spring. —Jonathon David Masters,


This is an impressive little book. Not quite 110 pages long, it’s a read of about an hour or so. The author has, however, managed to jam it full of facts and information about the Great Lakes. The author also sprinkles a strong environmental ethic throughout the book coupled with the belief that the democratic process can make a difference. —Bob Gross, The Oakland Press


Spring’s handy 108-page primer about the Great Lakes provides the curious with a solid overview of the lakes including their history, physical characteristics, denizens and the threats facing them, particularly from invasive species and pollution. —Dave LeMieux, The Muskegon Chronicle


The view of planet Earth as seen from a satellite in outer space shows the continents, deep blue oceans and white swirling clouds of vapor. The five Great Lakes show their distinct, interconnected shapes; unique bodies of fresh water.

Of all the planets our satellite cameras and telescopes have probed, only Earth looks inviting or habitable. A famous photograph taken from the moon shows Earth rising against a barren moonscape where nothing lives. In the foreground we see jagged rock, but rising in the distance is Earth with its liquid medium: water. Water and life are inseparable. Where there is life, there is water; where there is water, there is life.

All nations as well as all living things share the water and air supply that is the planet’s life support system; therefore we all share a responsibility for the cleanliness of the air, water, land and its living webs of life. Air and water never stop to show a passport, but circulate freely around the globe. The great swirling airstreams and water systems we can see from a satellite circulate continually.

If we thought of the Earth as an apple, a layer of life- supporting air, soil and water would only be as thick as the apple’s skin. Life on Earth is only possible as long as our limited life support system works.

We are all challenged to use our knowledge, creativity and common sense to keep the Great Lakes great. Can you think of ways to think globally and act locally.  excerpt from The Dynamic Great Lakes.

Rip Currents

September 12, 2017

The Dynamic Great Lakes Blog

Rip currents form offshore in a narrow channel. These currents can extend 1,000 feet, reach 100 feet in width, and travel up to 5 mph. This is slower than you can run, but faster than you or even an Olympic swimmer can swim. They are most prevalent after storms; some lasting a few hours, some (especially on the oceans) permanently.

■Don’t fight the current.

■Swim parallel to the shore to get out of the current. Rip currents are rarely more than 30 feet wide.

■If you can’t escape, float calmly until the current dissipates, then swim diagonally back to the shore.

■If you need help, call or wave for assistance.

Recognize a Rip Current:

■Murky water from sediments stirred up by the current.

■Different waves – larger and choppier.

■Foam or objects that move steadily offshore.
