More Progress Needed on Attacking the Threat of Microplastics in the Great Lakes

A January 2021 story by the Capital News Service headlined “Microplastics threaten Great Lakes, and not just the water” was one of the first I have seen recently about the threat of microplastics to our precious fresh waters. However, microplastics have been reported in the Great Lakes for more than 15 years. Researchers started to get interested in microplastics around 2012, but outside the scientific community, microplastic pollution in the Great Lakes hasn’t gained much interest. How much has been done to reduce microplastics? How much has been done to make the general public aware of this serious and growing threat?

Microplastics Invading the Food Chain

The Great Lakes face many challenges. Some are well-known, such as Asian carp, but some are almost invisible, such as microplastics. Small plastic detritus, termed “microplastics” or “microfibers,” are a widespread contaminant in aquatic ecosystems including the Great Lakes. Research reported in Environmental Science and Technology suggests that marine microplastic debris can have a negative impact upon zooplankton function and health.

Where do plastic bags and bottles go to die?

The U.S. Geological Survey estimates there are 112,000 particles of plastic per square mile of Great Lakes water. While the specific, causal effects plastics may have on human health are yet unknown and currently being researched, animal studies suggest that plastics and plastic byproducts affect digestive, respiratory, endocrine, reproductive, and immune systems.

Plastic-Free Picnics

Picnics with Less (or Zero) Plastic You may be surprised at how much trash we generate from what might seem a  low-impact picnic. Reducing picnic waste—especially plastics—is particularly important at a time when scientists are sounding the alarm about the buildup of small particles, or microplastics, in the Great Lakes Zero-Waste Picnic vs Typical Picnic… Read more »

Progress and Hope for the Environment

Ten years to save the planet from climate change. PFAS, microplastics, and invasive species. Wetland destruction and failing, polluting septic systems.  Sometimes it seems as though the only environmental news is bad news. Here’s an antidote, borne in a glass half-full.

Helping Great Lakes Communities Address Microplastic Pollution

Microplastics are plastics that measure no more than 5 millimeters long and reflect a growing environmental and public health concern. They come from a variety of sources. Some are intentionally manufactured. These are found in industrial or health and beauty products, the latter often used for scouring or exfoliation purposes.

The Geography of Hope Is Anchored in Our Precious Great Lakes

In his 1960 Wilderness Letter, conservationist and author Wallace Stegner famously coined the phrase “geography of hope,” referring to the impulse that led Americans to the wilderness idea. Now, in 2022, comes another prophet of hope, Maude Barlow. A lifelong and world-renowned champion of water, Maude has authored a book built on her career of activism. Its title, appropriately, is “Still Hopeful: Lessons from a Lifetime of Activism.” FLOW will host a livestream book event featuring Maude Barlow on Wednesday, June 15.
