America’s most dangerous crude oil pipeline threatens the future of the Great Lakes. That’s why young voters want it shut down.
Picture this: shimmery sunlight dancing on water. Deep blue crests over seafoam green before dissipating as waves meet the shore. The Chicago skyline gazes from a distance.
Running along Lake Michigan is one of my favorite pastimes at Northwestern University. We pride ourselves on having not one, but two beaches on campus that showcase the lake. The body of water is so wide it feels more like an ocean. The sound of the waves crashing onto the sand reminds me of the beaches back home in the San Francisco Bay Area.
But in the heart of the Great Lakes—where Lake Michigan meets Lake Huron—America’s most dangerous crude oil pipeline threatens 700 miles of coastline and our climate future.
By incorporating pipeline shutdowns in her climate platform, Harris can send a clear message that our future doesn’t rely on fossil fuels and that people can raise their families and thrive in the Great Lakes region.
Growing up in the Bay Area showed me that addressing the climate crisis is my generation’s mission. When I was a junior in high school in 2020, California experienced the worst wildfire in state history. Orange haze blanketed everything. With the air quality index skyrocketing, I did not dare go outside. Friends had to evacuate their homes, and a teacher of mine saw their house burn down. I knew I wanted a career focused on the environment when I realized our wildfires would grow worse every year without action.
Coming here for college, I was excited to explore a new part of the country and catch a break from the wildfire season. People tout the Midwest as a haven from the climate crisis, but environmental issues are aplenty here as well.
As the presidential election date gets closer with states in the Midwest crucial for the Harris-Walz ticket to pick up, looming threats to our Great Lakes should gain wider attention, all because of North America’s most dangerous fossil fuel pipeline. The Great Lakes hold one-fifth of the world’s available fresh water supply, but under it lurks an oil pipeline called Line 5, operated by Canadian oil corporation Enbridge, which could ruin millions of people’s drinking water, mar Lake Michigan’s beauty, and devastate our communities.
Right in the heart of the Great Lakes, the Line 5 oil pipeline is accelerating our climate crisis as we speak. Seventy-one years ago, Enbridge built Line 5 right through Michigan and Wisconsin and in some of the most sensitive areas in the Great Lakes as a shortcut to reach Ontario, Canada. A spill from Line 5 could reach the Lake Michigan shoreline where myself and hundreds of thousands of people live and walk by everyday.
Enbridge has a sordid history when it comes to pipeline infrastructure. They are responsible for one of the largest inland oil spills in United States history from another pipeline they operate in Michigan. They didn’t shut the valve for 17 hours, and remediation efforts took five years. A similar spill from Line 5 would significantly threaten the Great Lakes and the people who call this region home. When burned, the oil in Line 5 contributes more greenhouse gas emissions than the three most polluting coal-fired power plants in the country combined
With a major election this year, young voters across Michigan, Wisconsin, Illinois, and Minnesota will be a crucial voting bloc. For many of us—myself included—it’s going to be our first time voting in a presidential election. Taking action for the environment is at the forefront of my generation’s concerns, which means that delivering a tangible victory to protect our climate and Great Lakes is absolutely necessary. Enbridge’s Line 5 must be shut down and decommissioned. While a Harris-Walz administration can deliver by making this action happen, U.S. President Joe Biden can do so now by revoking this outdated pipeline’s permit.
The Great Lakes aren’t just the source of drinking water for over 40 million people. They’re our identity, creating a major reason why many of us live in the Midwest to begin with. When governments are putting more energy toward keeping fossil fuel pipelines in the Great Lakes than preserving the water we drink from, swim in, and fish from, it gives the impression that our natural resources aren’t worth saving. We cannot afford to be complacent in a time of crisis, and we must do better.
Indigenous Tribes, environmental groups, small businesses, and local residents across the Great Lakes have been fighting Enbridge’s Line 5 for over a decade because of the severe risks it poses to our air, land, water, and health. Enbridge has been operating illegally in Michigan since Gov. Gretchen Whitmer took action to stop the pipeline in 2020. And since 2012, Enbridge has been trespassing on the Bad River Band’s reservation in Wisconsin.
People are taking action against Line 5 by signing petitions, attending rallies in the U.S. and Canada, writing to their legislators, and emailing administration officials like U.S. Secretary of Transportation Pete Buttigieg for a shutdown. Volunteers have organized local businesses, faith communities, and Native Nations to attend teach-ins and community events and share information on Line 5’s dangers.
With Vice President Kamala Harris at the top of the ticket now, shutting down Line 5 should be a key issue in her policy platform. Gov. Whitmer won reelection handily after calling for a shutdown order, which shows that moving away from fossil fuels and decommissioning unsafe pipelines can be a winning electoral issue. Prioritizing a Line 5 shutdown could show that Harris can be one of the most pro-environment presidents in American history—her track record from California and her time in the Senate suggests that she prioritizes environmental policies like this. Shutting down the pipeline can set the stage for a new climate champion government.
A Line 5 shutdown is an achievable, easy win with real advantages. If climate is on the agenda for young voters in key Midwest states, Line 5 should be on the list of the vice president’s campaign priorities. By incorporating pipeline shutdowns in her climate platform, Harris can send a clear message that our future doesn’t rely on fossil fuels and that people can raise their families and thrive in the Great Lakes region. Young voters from the Midwest, like me, are firmly uniting behind one key message: Shut down Line 5.
"We need to take a broad approach to control sources that release PFAS into the atmosphere and into bodies of water," said one researcher, "since they eventually all end up in the lakes."
A first-of-its-kind study published this week shows that levels of toxic per- and polyfluoroalkyl substances, or PFAS, are now so ubiquitous in the environment that they have begun building up in the Great Lakes Basin after entering it through rainwater and the air, contaminating 95% of the United States' fresh surface water supply.
Researchers at Indiana University, Bloomington and Environment and Climate Change Canada published the study Thursday, revealing that "background levels" of PFAS, also called "forever chemicals," are so high that atmospheric counts were consistent throughout the basin.
"The PFAS in rain could be carried from local sources, or have traveled long distances from other regions. Regardless, it is a major source of pollution that contributes to the lakes' levels," reported The Guardian on Saturday.
The levels of PFAS in precipitation did not correlate with whether or not an area in the Great Lakes Basin was heavily industrialized, lead author Chunjie Xia, a postdoctoral associate at Indiana University, told The Hill.
"The levels in precipitation don't depend on the population," said Xia. "They are similar in Chicago, which is heavily populated, and at Eagle Harbor, Michigan, where there's maybe 500 people living in a 25-kilometer radius."
"That tells us the levels are ubiquitous," he said. "This is the first time we've seen that. We've never seen that for other pollutants before."
Within the basin, however, levels of PFAS were higher near urban areas.
Twenty percent of the world's freshwater is held in the Great Lakes Basin, while 10% of the U.S. population and 35% of Canadians live in the region.
In 2023, Duke University and the Environmental Working Group analyzed fish samples collected from the Environmental Protection Agency's monitoring program for the Great Lakes, and found that eating just one locally caught freshwater fish could be the equivalent of drinking PFAS-contaminated water for a month.
Forever chemicals have earned their nickname because they do not naturally break down and can continuously remain in and move through the environment. PFAS are used by dozens of industries to make products heat-, water-, and stain-resistant.
European lawmakers have proposed a ban that could go into effect as early as 2026, but Reuters reported Wednesday that the law could include exemptions for certain industries.
Last month, the Biden administration finalized a rule setting limits on PFAS in drinking water.
"We need to take a broad approach to control sources that release PFAS into the atmosphere and into bodies of water," Marta Venier, a co-author of the new study, told The Guardian, "since they eventually all end up in the lakes."
"Today's decision is another notch in a long history of ignoring the rights of tribal nations," said one Indigenous leader.
Days after climate advocates applauded Michigan Gov. Gretchen Whitmer's signing of a package of clean energy bills that one campaigner said would "translate into better air, water, and health for everyone," state regulators took several steps back from a sustainable future as they approved a key permit for Enbridge's Line 5 expansion project beneath the Great Lakes.
In a 2-0 vote with one member abstaining, the Michigan Public Service Commission (MPSC) approved siting for the project, granting Canadian oil firm Enbridge permission to build a concrete tunnel beneath the Straits of Mackinac—which connect Lake Michigan and Lake Huron—to house a four-mile section of its 645-mile petroleum pipeline.
The company can't break ground on the project without approval from the U.S. Army Corps of Engineers, which isn't expected to announce its decision until 2026, but Indigenous tribes and advocacy groups that have fought for years to stop the pipeline from being built expressed outrage that the commission approved the permit despite well-documented objections.
All federally recognized tribes in Michigan have passed resolutions opposing Line 5, which safety experts have warned puts the Great Lakes at risk for a massive explosion and oil spill.
"Today's decision is another notch in a long history of ignoring the rights of tribal nations," said Whitney Gravelle, president of the Bay Mills Indian Community. "We must act now to protect the peoples of the Great Lakes from an oil spill, to lead our communities out of the fossil fuel era, and to preserve the shared lands and waters in Michigan for all of us."
Tribes have said the project would violate their treaty rights and that Enbridge has not proven it can operate the tunnel safely. The company's Line 6B oil spill in 2010 contaminated nearly 40 miles of the Kalamazoo River.
"Disappointment isn't a big enough word," Rebecca Liebing, attorney for Bay Mills, told Michigan Bridge after the MPSC vote was announced. "There's no ambiguity regarding how the tribes feel about this matter... We're not done fighting."
The lakes hold 84% of North America's surface freshwater, and the Line 5 expansion would be the largest underwater hazardous liquids tunnel ever completed, said the coalition Oil and Water Don't Mix (OWDM).
"With this action, the Michigan Public Service Commission is putting Michigan in uncharted, dangerous territory while ignoring warnings by independent industry experts who testified during the MPSC's proceedings," said Sean McBrearty, a campaign coordinator for OWDM. "Never before has an oil tunnel that also carries other hazardous liquids been built in one of the most ecologically sensitive spots on Earth."
McBrearty pointed out that Enbridge already operates other oil pipelines in the Straits of Mackinac, and said there is "an open question whether Enbridge intends to build the tunnel or is simply using the project as a diversion and delay from shutting down the existing twin oil pipelines."
"Moreover, the Line 5 tunnel will worsen the impacts of the climate crisis by adding 27 million metric tons of polluting and climate altering carbon into the atmosphere, equivalent to 10 coal-fired power plants," said McBrearty, calling on President Joe Biden to revoke the presidential permit for Line 5.
Whitmer campaigned on closing down Line 5, but Enbridge has claimed the governor has no authority to shut down its pipelines because it runs between the U.S. and Canada and is subject to federal regulations.
A spokesperson for the governor told Michigan Bridge that Whitmer is reviewing the MPSC's decision and that her goal "has always been getting the pipelines out of the water as quickly as possible."
Christopher Clark, senior attorney for Earthjustice, which represented Bay Mills as it presented its case objecting to Line 5 to the MPSC, said the commission ignored "the concerns of tribal communities in favor of the profit of a fossil fuel company."
"The evidence before the commission demonstrated that the proposed tunnel would put the Great Lakes region at serious risk and profoundly endanger the identity and lifeways of the Bay Mills Indian Community, a sovereign tribal nation whose relationship to these waters preexists the United States," said Clark. "We will use every open avenue to shut down Line 5 in order to avert an environmental catastrophe and slow the unthinkable impacts of climate change.”"Every single one of us has agency and a responsibility to take action, honor the treaties, and protect Mother Earth," asserted one Oneida Nation leader. "It is the time to be brave and courageous."
Native American women leaders and more than 150 allied advocacy groups from across the United States on Thursday implored the Biden administration to decommission a Canadian-owned oil and gas pipeline that, according to one group, has spilled more than a million gallons of fossil fuels in over 30 incidents during the past 55 years.
In a letter to President Joe Biden, Environmental Protection Agency (EPA) Administrator Michael Regan, and other administration officials, leaders of the Indigenous Women's Treaty Alliance—which is facilitated by the Women's Earth and Climate Action Network (WECAN)—called on the president to "immediately revoke the presidential permit for Canada's deteriorating Enbridge Line 5 pipeline before environmental calamity strikes with oil spills into the Great Lakes."
"We write to you as Indigenous grandmothers, mothers, aunties, daughters, sisters, and relatives. We are of the Great Lakes, where our sacred food manoomin (wild rice) grows on water," the letter states. "We hold a responsibility to protect our water, our ecosystems, and our cultural lifeways for the next seven generations."
Manoomin "is fundamental to the physical, spiritual, and cultural survival of the Bad River Band of Lake Superior Chippewa," the letter's signers explained. "Our sovereignty and treaty-protected rights to hunt, fish, and gather food and medicine are all at risk. Diverse fish populations spawn in the Bad River Watershed. These fish are economically and culturally vital to the Bad River Band, Red Cliff Band of Lake Superior Chippewa, and the entire region."
Treaty rights and manoomin were at the center of Indigenous-led opposition to replacing Line 3, another Enbridge pipeline running from Canada through the Great Lakes region. Despite fierce resistance from Indigenous, climate, and environmental activists, the Biden administration declined to block Line 3's replacement, which went online in October 2021.
"An oil disaster would permanently devastate the exceptional ecology of the watershed, the wild rice, and fish populations," the new letter continued. "At the Bad River Reservation, recent flooding has eroded one riverbank to within 11 feet or less of Line 5's centerline, creating an immediate threat."
Last September, U.S. District Judge William Conley found that Enbridge was trespassing on lands belonging to the Bad River Band of Lake Superior Chippewa in northwestern Wisconsin, and profiting off Line 5 at the tribe's expense. However, Conley said earlier this month that since the tribe cannot prove that an "emergency" exists along the flooded riverbank, he is unlikely to order Enbridge to shut down the pipeline.
"This is a nearly 70-year-old pipeline running almost two decades past its engineered lifespan," the new letter stresses. "Erosion from receding waters or the next rainfall could cause a 'guillotine rupture'—a vertical break causing oil to gush from both sides, poisoning the Bad River watershed and Lake Superior."
As the Oil & Water Don't Mix coalition explained:
Nearly 23 million gallons of oil daily flow through two aging pipelines in the heart of the Great Lakes, just 1.5 miles west of the Mackinac Bridge. Constructed during the Eisenhower administration in 1953, the two 20-inch-in-diameter [pipelines]... lie exposed at the bottom of the Straits of Mackinac—a busy shipping channel...
Line 5 has spilled 33 times and at least 1.1 million gallons along its length since 1968.
The pipelines in the Straits of Mackinac cross one of the most ecologically sensitive areas in the world. The Great Lakes are home to 21% of the world's fresh surface water. The pristine straits area supports bountiful fisheries, provides drinking water to thousands of people, and anchors a thriving tourism industry with historic and beautiful Mackinac Island right in the center.
In November 2020, Michigan Gov. Gretchen Whitmer moved to revoke Line 5's easement, with a shutdown order coming the following May. However, Enbridge ignored Whitmer's order and kept running the pipeline.
"Revoking the presidential permit and forcing Enbridge to cease Line 5's operations is consistent with your administration's directives for climate, nation-to-nation relations, and environmental justice. It is also consistent with the knowledge we share that the Great Lakes—one-fifth of the world's surface freshwater at a time of growing water scarcity—are invaluable treasures that must be protected, regardless of political pressures, special interests, and short-term profits," the new letter argues.
"Water is life," the signers added. "We are... calling on you to protect essential water, as well as wild rice, fisheries, and cultural survival."
Jannan J. Cornstalk, a citizen of Little Traverse Bay Bands of Odawa Indians and director of the Water is Life Festival, said in a statement Thursday that "our very lifeways and cultures hang in the balance as Line 5 continues to operate illegally in Indigenous territories and water."
"These are our lifeways—when that water is healthy enough that rice is growing—that not only benefits our communities, but that benefits everybody up and downstream," Cornstalk added. "Allowing Line 5 to continue to operate is cultural genocide, and the Biden administration must listen and shut down Line 5. That water is our relative, and we will do whatever it takes to protect our water, our sacred relative."
Aurora Conley of the Bad River Ojibwe and Anishinaabe Environmental Protection Alliance said: "I am calling on the Biden administration to shut down Line 5 immediately. Our territories and water are in imminent danger, and we do not want to see irreversible damage to our land, water, and wild rice."
"We do not want our lifeways destroyed," Conley added. "The Ojibwe people are here in Bad River because of the wild rice. A rupture from this oil spill will irreversibly harm the Great Lakes and wild rice beds. This is unacceptable. We will not stand for this. Shut down Line 5 now."
Carrie Chesnik of the Oneida Nation Wisconsin and founder of the Treaty Land Trust, asserted that "we have an opportunity here to shut down the Line 5 pipeline, and protect what we all hold dear."
"We all have the responsibility and agency to act in a good way, to care for the land and waters," she continued. "What our communities have known for a long time is that the water is hurting, Mother Earth is hurting, and pretty soon we won't have clean water for our kids, for future generations."
"As a Haudenosunee woman, an auntie, daughter, and sister, I have an inherent responsibility to the water and our children," Chesnik added. "Every single one of us has agency and a responsibility to take action, honor the treaties, and protect Mother Earth. It is the time to be brave and courageous."
"The extent that PFAS has contaminated fish is staggering," said the lead researcher, advocating for "a single health protective fish consumption advisory for freshwater fish across the country."
Yet another study on Tuesday raised the alarm about the dangers of "forever chemicals," revealing that eating just one locally caught freshwater fish in the continental United States can be equivalent to drinking contaminated water for a month.
Per- and polyfluoroalkyl substances (PFAS) are widely called forever chemicals because they persist in the human body and environment for long periods. Despite public health concerns, the manufactured chemicals have been used in products ranging from firefighting foam and waterproof clothing to nonstick pans and food packaging.
"These test results are breathtaking."
Duke University and the Environmental Working Group (EWG) researchers analyzed data for over 500 fish fillet samples collected across the country from 2013-15 for a pair of U.S. Environmental Protection Agency (EPA) monitoring programs: the National Rivers and Streams Assessment and the Great Lakes Human Health Fish Fillet Tissue Study.
"Identifying sources of PFAS exposure is an urgent public health priority," said study co-author and EWG senior scientist Tasha Stoiber in a statement.
"PFAS contaminate fish across the U.S., with higher levels in the Great Lakes and fish caught in urban areas," she noted. "PFAS do not disappear when products are thrown or flushed away. Our research shows that the most common disposal methods may end up leading to further environmental pollution."
Perfluorooctanesulfonic acid (PFOS) contributed significantly to the high levels in the samples. U.S. manufacturers have largely phased out that PFAS, but it has been used in firefighting foam and was a main component of Scotchgard, a fabric protector by 3M—which announced last month that it plans to exit the PFAS market by the end of 2025.
As the new study states:
The two datasets indicate that an individual's consumption of freshwater fish is potentially a significant source of exposure to perfluorinated compounds. The median level of total targeted PFAS in fish fillets from rivers and streams across the United States was 9,500 ng/kg, with a median level of 11,800 ng/kg in the Great Lakes. PFOS was the largest contributor to total PFAS levels, averaging 74% of the total.
"These test results are breathtaking," said Scott Faber, EWG's senior vice president for government affairs. "Eating one bass is equivalent to drinking PFOS-tainted water for a month."
Specifically, the researchers calculated that eating one 8 oz. serving of fish is equivalent to consuming one month of drinking water with PFOS at 48 parts per trillion (ppt), which is 2,400 times the interim U.S. EPA health advisory.
"People who consume freshwater fish, especially those who catch and eat fish regularly, are at risk of alarming levels of PFAS in their bodies," said co-author and EWG senior scientist David Andrews. "Growing up, I went fishing every week and ate those fish. But now when I see fish, all I think about is PFAS contamination."
The study stresses that "the exposure to chemical pollutants in freshwater fish across the United States is a case of environmental injustice that especially affects communities that depend on fishing for sustenance and for traditional cultural practices."
While the study was published in the journal Environmental Research, EWG's website features an interactive map that details the key findings nationwide.
The researchers found that the median levels of total PFAS in freshwater fish were 278 times higher than those in commercial fish tested by the U.S. Food and Drug Administration from 2019-22.
"It's incredible how different they are," Andrews told The Hill. According to the outlet:
Some commercially caught fish may be less contaminated because they are grown in controlled aquaculture environments, Andrews explained. Meanwhile, large-scale ocean fishing often occurs farther offshore, where PFAS pollution would be more diluted, he added.
Andrews acknowledged, however, that the data on commercially caught fish is much more recent than the freshwater contamination figures.
He also recognized that with the industrial phaseout of PFOS production, the pollution "levels in rivers and streams do seem to be decreasing, which is important."
"At the same time, the levels are still so high that any fish consumption likely impacts [human blood] serum levels," Andrews said. "But they are moving in the right direction, which I think is some good news, at least in terms of the rivers and streams."
Despite some progress—including small steps last year by the EPA—the researchers and others pointed to the findings as evidence of the need for further action on PFAS.
"The extent that PFAS has contaminated fish is staggering," said lead researcher Nadia Barbo, a graduate student at Duke. "There should be a single health protective fish consumption advisory for freshwater fish across the country."
EWG's Faber declared that "for decades, polluters have dumped as much PFAS as they wanted into our rivers, streams, lakes, and bays with impunity. We must turn off the tap of PFAS pollution from industrial discharges, which affect more and more Americans every day."
"The EPA needs to move swiftly to set regulations for the industries most likely to be dumping PFAS into the environment," he added. "Downstream communities especially have suffered the consequences of unregulated PFAS discharges for far too long."
