A new bid to safeguard Mississippi River amid growing environmental concerns

By Madeline Heim, Milwaukee Journal Sentinel

A proposal to create a federal funding program to protect the Mississippi River is back in front of Congress.

Democratic Sen. Tammy Baldwin of Wisconsin announced Wednesday that she plans to introduce the Mississippi River Restoration and Resilience Initiative in the Senate. Democratic Rep. Betty McCollum of Minnesota will bring the same bill forward in the House.

The proposal is nearly the same as one introduced by McCollum in 2021. It’s modeled after programs that protect other major bodies of waters across the U.S., like the Great Lakes Restoration Initiative and the Chesapeake Bay Program.

Advocates for the Mississippi River argue that the river is long overdue to have its own such program. Millions of Americans rely on it for drinking water, commerce and recreation, and its floodplains provide food and habitat for hundreds of fish and wildlife species. But it’s facing a multitude of challenges, from extreme weather to habitat loss to persistent agricultural and industrial pollution. That pollution contributes to the dead zone in the Gulf of Mexico, which last year was almost as big as Yellowstone Park.

Even in the past few years, the river has experienced the impacts of a changing climate, said Kelly McGinnis, executive director of the Mississippi River Network. Last spring, communities along the upper river saw near-record floodwaters, bookended by severe droughts that slowed shipping traffic to a crawl.

“If anything, since (this legislation) was first introduced, the conditions of the world we live in just keep showing us that there is an urgent need to address these problems, and they’re not solving themselves,” McGinnis said.

Evidence mounts linking air pollution to Parkinson’s disease

By Grace van Deelen

New research adds to evidence that people living in areas with high air pollution are at a higher risk of developing Parkinson’s disease, a progressive neurological disorder.

The research found a nationwide association between incidents of Parkinson’s and annual average particulate matter air pollution, also known as PM 2.5. Researchers found that at the highest annual exposure level, participants were 25% more likely to develop Parkinson’s disease, compared to those with the lowest exposure.

The findings are expected to be presented at the American Academy of Neurology’s meeting in April and published in the journal Neurology. The work was funded by grants from the US Department of Defense, the National Institutes of Health National Institute of Environmental Health Sciences, and the Michael J. Fox Foundation for Parkinson’s Research.

“It’s a very compelling story that we see,” said Brittany Krzyzanowski, a scientist at the Barrow Neurological Institute and lead author on the new study.

Researchers used data from over 22 million Americans, 83,674 of whom had reported a Parkinson’s diagnosis. They analyzed that data alongside geographical data showing the amount of PM 2.5 in the atmosphere. PM 2.5 is a type of air pollution that comes from vehicle exhaust, forest and grass fires, and other industrial processes, meaning that communities near highways and industrial areas are most likely to have high exposure.

The link between the disease and PM 2.5 has been suggested in numerous other studies, including a 2022 review of existing research that found air pollution to be “an emerging risk factor in the development of Parkinson’s disease.”

As well, a 2018 study of more than 2 million Ontario adults found that long-term exposure to PM 2.5 was associated with a 4% increase in instances of Parkinson’s, while a 2020 study of 63 million US adults found an association between PM 2.5 exposure and hospitalization for Parkinson’s.
