When you visit one of the Great Lakes, whether it’s a sandy beach or a rocky coastline, it’s hard to imagine how something so big could be affected so profoundly by alien invasive species, or pollution, or climate change.

On Thursday, environmental groups and Native Americans plan to present Enbridge Energy with symbolic eviction notices. They want Enbridge to abide by Governor Gretchen Whitmer’s order to shut down Line 5 in the Straits of Mackinac.

Enbridge Energy technically has one more day to shut down the Line 5 pipeline in the Straits of Mackinac, but even the pipeline’s most vocal opponents acknowledge slim odds that the oil actually stops flowing right away.

There’s been a lot of news about the amount of plastic debris in the oceans. But plastic pollution is also affecting the Great Lakes. A study out of the Rochester Institute of Technology estimates 22 million pounds of plastic debris enters the Great Lakes from the U.S. and Canada each year.

Right now, scientists are on a ship taking samples and measurements of the Great Lakes. They’re trying to determine how the lakes will fare this year and watching for trends.

As Canadian officials lobbied a Michigan Senate committee in March to keep the Line 5 pipeline open, Sen. Winnie Brinks (D-Grand Rapids) grew frustrated with a conversation that, up to that point, had focused mainly on the immediate economic and safety implications of a possible shutdown.

Climate change in the Great Lakes region means more intense storms. Already some towns are finding they’re flooding where they never have before. One city in Michigan is finding the solution is nature.

Midland and other cities were hit hard by a flood caused by heavy rains and the failure of a weak dam.

Climate change is altering lakes so that some fish species could be lost. Ice coverage is declining over the decades.

Intrigued by warming winters, researchers from the University of Michigan set out in 1989 to formally measure changes in the geographical distribution of plants and animals in the dense pine and hardwood forests of northern Michigan.
