Remember the canary in the coal mine? If the caged canary died, that was an urgent early warning for miners that the air was too dangerous to breathe and to get above-ground as quickly as possible. Now there’s evidence from Southeast Michigan that the American robin can provide an early warning about dangerous lead levels in the soil. A new study in the journal “Urban Ecosystems” found that high blood lead levels in robins can accurately predict where soil is contaminated. 
Exposure of children to lead is linked to damage to their nervous system and brain, learning and behavioral problems, and speech and hearing problems, according to the Centers for Disease Control and Prevention. There is relatively little knowledge about the health impacts of blood lead levels on songbirds such as robins.

Minnesota debates what counts as carbon-free energy

By |

By Ruth Thornton
A recent decision by Minnesota’s Public Utilities Commission could mean that wood and trash will be considered “carbon-free” energy sources under the state’s new climate law. The law, passed in 2023, requires all electricity to come from carbon-free sources by 2040, with interim goals defined for 2030 and 2035. However, it did not define which energy sources meet that definition and instead tasked the PUC to make that decision with public input. At first glance, the definition of carbon-free energy seems straightforward. But there is disagreement over the details.

The Michigan Department of Natural Resources is looking for deals to create more green space in populated areas as part of an updated public lands strategy. The goal is to equitably provide public access to green space, wildlife habitat and public hunting closer to where people live, department officials say. Efforts in the past two years include acquisitions in Van Buren, Monroe and Ionia counties. 
Those involved buying private land adjacent to public land to consolidate green spaces. 
Scott Whitcomb, the director of the DNR’s Office of Public Lands, said a major pending deal involving Black River Ranch in Sanilac County is expected to close by the end of 2025. That property acquisition will bring in about 8,844 acres, including over 14 miles of the Black River, the East Branch of the Black River, Stewart Creek and three lakes including 150-acre Silver Lake. It will become part of the Pigeon River Country Forest Management Unit.

New book explores the wonders of inland waters

Around 97% of all the water on the planet is in the vast oceans that cover more than two-thirds of its surface. “But Seas are not the only body of water that make Earth special,” ecologist David Strayer writes in his new book. “Beyond the Sea: The Hidden Life in Lakes, Streams, and Wetlands,” presents the lesser-known facts of freshwater ecosystems and how they affect our everyday lives. 
Before retiring in 2016, Strayer spent nearly 50 years studying freshwater ecology, most recently at the Cary Institute of Ecosystem Studies, where he developed an expertise in the nearby Hudson River. The book lays out the good, the bad and the ugly of the world’s inland water bodies, which Strayer reports are home to some 2,600 plant species and 150,000 animal species, about half of which are insects. While celebrating that abundance of life the book doesn’t shy away from the serious threats and challenges that inland waters face, including pollution, invasive species, climate change and the damaging impacts of dams and water diversions.

Wolves could expand across the eastern U.S.—but they might need help

By |

Gray wolves could thrive in the eastern United States well beyond their current range in the Great Lakes region, but they might have a hard time reaching other suitable habitats without human intervention, researchers say. Wolves once had the largest known range of any land mammal but they were nearly exterminated in the United States in the early 1900s after persecution by humans. 

Their population only recovered after they were placed under federal protection in the 1970s. They have since recolonized some areas where they once flourished, including in Minnesota, Wisconsin and the Upper Peninsula of Michigan. 

A 2022 study analyzed which areas in the eastern U.S. still have suitable habitat for wolves and are connected enough to each other so wolves might be able to travel between them. 

To do that, the researchers used survey data collected between 2018 and 2020 by biologists working for the natural resource departments in Minnesota, Wisconsin and Michigan. 

They then modeled the characteristics of the habitats where wolves were found and predicted where else in the eastern U.S. large tracts of suitable areas occur. They also modeled how connected to each other those areas are. They found that six areas had good habitat and were large enough to sustain wolves, but the animals occur in only one of them, the western Great Lakes.

Michigan is part of an effort to build hydrogen infrastructure in the Midwest. 
The Midwest Alliance for Clean Hydrogen (MachH2) has received $22 million from the U.S. Department of Energy to plan several projects, three of which are in Michigan. The alliance, backed by the Michigan Infrastructure Office, wants to expand the Flint Mass Transportation Authority’s fleet of hydrogen fuel buses. 
There are plans to build a hydrogen production facility in Ypsilanti, in partnership with the American Center for Mobility. And the other proposed project would be a hydrogen fuel truck stop in Detroit. Hydrogen is a clean energy alternative to electrifying heavy-duty trucks, according to the alliance. Electrifying big trucks, especially for long-haul travel, is challenging with current technology because of the size, weight, and charge time of electric batteries.

The popularity of a cheaper and environmentally friendly burial alternative is rising in the U.S., but Michigan has yet to legalize it. Human composting transforms the body into soil, according to Earth Funeral, a human composting company with locations in Washington and Nevada.Human. Human composting, which accelerates the natural decomposition process, is legal in 12 states, according to Recompose, another company in the field, with Washington the first to legalize the practice in 2020. 

Similar legislation has been introduced in other states, but not Michigan. Haley Morris of Earth Funeral said Michigan residents still have access to human composting and the company often gets interest from people in Michigan. “We can coordinate if people want to pre-plan, or even if they have lost a loved one and are in immediate need to transport their loved one to one of our facilities in Washington state or Nevada, and have their loved one undergo the natural organic reduction process there,” she said.

Three miles of westbound I-94 in Wayne and Washtenaw counties are already set up for connected and automated vehicles. Now the Department of Transportation wants public feedback on the proposed project, which would include almost 40 miles of I-94 if completed. 

 It’s proposed to eventually span about 39 miles between Ann Arbor and Detroit. The lane would be reserved for connected and automated vehicles, or CAVs for short. Connected vehicles aren’t quite driving themselves yet, but they’re equipped to talk to other vehicles. The department is assessing the project’s impact on the environment and communities around it.

For the third year in a row, Michigan’s recycling rate has hit a record-high, according to the Department of Environment, Great Lakes and Energy. Michigan’s recycling rate has risen from about 14% before 2019 to over 23% now. Officials say they expect the state will reach a 30% recycling rate by 2029. 
According to the most recent figures from the U.S. Environmental Protection Agency, the national recycling rate is currently 32% with a goal to increase that number to 50% by 2030. The state department aims to further expand recycling access with over $5 million in new grants to support projects in Metro Detroit, Genesee County, Lansing, Southwest Oakland County, Isabella County, Van Buren County, Marquette County, Sterling Heights and Madison Heights. Genesee County is set to receive $900,000 to establish its first-ever countywide recycling drop-off center. 
Cody Roblyer, the lead planner for the Genesee County Metropolitan Planning Commission, said the demolition phase will be completed at the previous site of McDonald Dairy Company, directly off I-475 in Flint by early 2025.

Great Lakes region hit hard by steel industry pollution, report finds

By |

 

By Joshua Kim 
Pollution from coal-based steel production causes hundreds of premature deaths each year, with people in  the Great Lakes region bearing much of the burden, according to a recent report. The nonprofit research group Industrious Labs looked at 17 coal-based steel plants and coke facilities operating in the United States and the health and environmental problems they cause in surrounding communities. 
Emissions from these facilities include pollutants linked to significant health and environmental problems, including nitrogen oxides, sulfur dioxide, fine particulate matter and lead. 
Together their pollution is responsible for as many as 892 premature deaths per year, according to Industrious Labs. Those emissions also trigger around 250,000 cases of asthma symptoms annually, are linked to cancer rates 12% to 26% higher than the national average and result in up to $13.2 billion in annual health care costs, the report says. 
The group based its results on an Environmental Protection Agency computer model that uses self-reported industry data. “Communities don’t have access to this type of information,” said Hilary Lewis, the steel director at Industrious Labs. “By doing this report, we are giving people who live closest to these facilities, who are most impacted, who are most likely to be experiencing these health harms, a tool in advocating for cleaner alternatives.”
All but one of the country’s coke plants and all of its operating coal-based steel plants are located in Great Lakes states, according to the report.
