For generations, cod fishing was a way of life in Newfoundland and Labrador, the easternmost province in Canada. But in 1992, after cod stocks in the north Atlantic plummeted, the federal government imposed a moratorium on cod fishing. It was to last for 32 years until it was lifted in June 2024.
The decision was controversial and in this week’s episode of The Conversation Weekly podcast we speak to a fisheries expert to shed light on what’s happened. It offers a cautionary tale for those politicians trying to balance the complex demands of protecting ecosystems that also support substantial economies. https://embed.acast.com/60087127b9687759d637bade/6735d6305ff3c5f14422c352
Newfoundland is a sleepy place with colourful wooden houses and icebergs that pass by its northern shores in early summer. The island is perched out in the north Atlantic near the grand banks, some of the most prolific fishing waters in the world.
Fishing has been the backbone of the economy for centuries, and so when the Canadian government imposed a cod moratorium in 1992 it had a huge impact, with an estimated 30,000 people in Newfoundland and Labrador out of work overnight. Some cod fishing was permitted in inshore waters from the late 1990s in boats less than 20 metres long, but all commercial offshore trawler fishing was prohibited.
A number of factors led to the decline of the cod population, but the most significant was overfishing, explains Tyler Eddy, a research scientist in fisheries science at Memorial University of Newfoundland.
When they started to put the brakes on the fishing it was already too late, the population had been already reduced to a low level.
The expectation was that the moratorium would last for a few years, enough for the cod stocks to recover. But that didn’t happen, explained Eddy.

Moving goalposts
There was a little uptick in 2016, but the recovery stalled. Then, in 2023, a new historical dataset tracking how many baby cod made it to adulthood back in the boom years of the 1960s was introduced into the annual assessment of the cod stocks.
The effect, explains Eddy, who was one of the scientists involved in the decision, was to reduce what experts believed the cod population could recover to. It also lowered the reference points for whether a stock is in the critical, cautious or healthy zone.
It would be as if a car was doing 80km/hour and the speed limit used to be 60km/hour, so it was over the speed limit. Now the speed limit is changing to 80km so the car is actually doing within the speed limit. The car hasn’t changed speed at all, it’s just the reference point has changed.
And this is what happened: the 2024 assessment of cod stocks using this new dataset put cod in the cautious zone, rather than the critical zone.
In June, the Canadian government used this shift to justify lifting the moratorium. It increased the total allowable catch for the year from 13,000 to 18,000 tonnes and reopened some cod fishing in offshore waters in 2024, including to some international trawlers.
It’s since emerged that this decision went against the scientific advice of officials within Fisheries and Oceans Canada, the department which manages fishing. They had recommended maintaining the existing level of total allowable catch and continuing to limit it to inshore fishers.
A spokesperson for Fisheries and Oceans Canada told The Conversation that it makes fishery decisions informed by the best available science and a range of other factors, including socioeconomic considerations.
Newfoundland is now waiting until early 2025 when the next stock assessment of the Atlantic cod takes place, to see what the impact will be. Eddy explained how finely balanced the situation is:
Even though we are in the cautious zone, we’re just barely in the cautious zone … we’ve just barely crossed this threshold, and there’s actually a probability that we could still be within the critical zone. And if we look at the projections for the next three years, I think there’s a two-thirds to three-quarter chance that we’re going to end up back in the critical zone.

Volcanoes inspire awe with spectacular eruptions and incandescent rivers of lava, but often their deadliest hazard is what quietly falls from the sky.
When a large volcano erupts, as Mount Spurr appears close to doing about 80 miles from Anchorage, Alaska, it can release enormous volumes of ash. Fine ash can infiltrate the lungs of people and animals who breathe it in, poison crops and disrupt aquatic life. Thick deposits of ash can collapse roofs, cripple utilities and disrupt transport networks.
Ash may lack the visual impact of flowing lava, but as a geologist who studies disasters, I’m aware that ash travels farther, lasts longer and leaves deep scars.

Volcanic ash: What it is, and why it matters
Volcanic ash forms when viscous magma – molten rock from deep beneath Earth’s surface – erupts, exploding into shards of rock, mineral and glass carried in a near-supersonic stream of hot gas.
Towering clouds of ash rise several miles into the atmosphere, where the ash is captured by high-altitude winds that can carry it hundreds or even thousands of miles.
As the volcanic ash settles back to Earth, it accumulates in layers that typically decrease in thickness with distance from the eruption source. Near the vent, the ash may be several feet deep, but communities farther away may see only a dusting.
When Mount Spurr erupted in 1992, a dark column of ash and gas shot into the atmosphere from the volcano’s Crater Peak vent. Wind patterns determine where the ash will fall.U.S. Geological Survey
Breathing danger: Health risks from ash
Breathing volcanic ash can irritate the throat and lungs, trigger asthma attacks and aggravate chronic respiratory conditions such as COPD.
The finest particles pose the greatest risk because they can penetrate deep into the lungs and cause death by asphyxiation in the worst cases. Mild, short-term symptoms often resolve with rest. However, the long-term consequences of ash exposure can include silicosis, a lung disease and a possible cause of cancer.
The danger increases in dry regions where fallen ash can be kicked up into the air again by wind or human activity.
Risks to pets and livestock
Humans aren’t the only ones at risk. Animals experience similar respiratory symptoms to humans.
Domestic pets can develop respiratory distress, eye inflammation and paw irritation from exposure to ash.

Livestock face greater dangers. If grazing animals eat volcanic ash, it can damage their teeth, block their intestines and poison them.
During the 2010 Eyjafjallajökull eruption in Iceland, farmers were advised to shelter sheep and cattle because the ash contained fluoride concentrations above the recognized safety threshold of 400 parts per million. Animals that remained exposed became sick and some died.
Harm to crops, soil and water
Soil and crops can also be damaged. Volcanic ash alters the acidity of soil and introduces harmful elements such as arsenic and sulfur into the environment.
While the ash can add nutrients such as potassium and phosphorus that enhance fertility, the immediate impact is mostly harmful.
Ash can smother crops, block sunlight and clog the tiny stomata, or pores, in leaves that allow plants to exchange gases with the atmosphere. It can also introduce toxins that render food unmarketable. Vegetables, fruit trees and vines are particularly vulnerable, but even sturdy cereals and grasses can die if ash remains on leaves or poisons emerging shoots.
Following the 1991 Mount Pinatubo eruption, vast tracts of farmland in central Luzon in the Philippines were rendered unproductive for years due to acidic ash and buried topsoil. If multiple ashfalls occur in a growing season, crop failure becomes a near certainty. It was the cause of a historic famine that followed the eruption of Mount Tambora in 1815.
Ash from a 1953 eruption of Mount Spurr included very fine grains, like powder. The ash cloud reached about 70,000 feet high and left Anchorage under a blanket of ash up to a quarter-inch deep, according to a U.S. Geological Survey report at the time.James St. John via Wikimedia Commons, CC BYElectron microscope images of ash show how sharp the shards are.

Ash can also contaminate surface water by introducing toxins and increasing the water’s acidity. The toxins can leach into groundwater, contaminating wells. Fine ash particles can also settle in waterways and smother aquatic plants and animals. During the 2008 Chaitén eruption in Chile, ash contamination led to widespread fish deaths in the Río Blanco.
Ash can ground airplanes, gum up infrastructure
Ash clouds are extremely dangerous to aircraft. The glassy ash particles melt when sucked into jet turbines, clog fuel systems and can stall engines in midair.
In 1982, British Airways Flight 9 lost power in all four engines after flying through an ash cloud. A similar incident occurred in 1989 to KLM Flight 867 over Alaska. In 2010, Iceland’s Eyjafjallajökull eruption grounded more than 100,000 flights across Europe, disrupting travel for over 10 million passengers and costing the global economy billions of dollars.
Volcanic ash can also wreak havoc on infrastructure by clogging water supplies, short-circuiting electrical systems and collapsing roofs under its weight. It can disrupt transportation, communication, rescue and power networks, as the 1991 eruption of Mount Pinatubo in the Philippines dramatically demonstrated.
What to do during ashfall
During an ashfall event, the most effective strategy to stay safe is to stay indoors as much as possible and avoid inhaling ash particles.
Anyone who must go outside should wear a properly fitted N95 or P2 mask. Cloth masks provide little protection against fine ash. Rainwater tanks, troughs and open wells should be covered and monitored for contamination. Livestock should be moved to clean pastures or given uncontaminated fodder.
The challenges Alaska is facing if Mount Spurr erupts.
To reduce structural damage, ash should be cleared from roofs and gutters promptly, especially before rainfall.
Older adults, children and people who are sick are at greatest risk, particularly those living in poorly ventilated homes. Rural communities that are dependent on agriculture and livestock are disproportionately affected by ashfall, as are low-income people who lack access to clean water, protective masks or safe shelter.
Communities can stay informed about ash risks through official alerts, including those from the Volcanic Ash Advisory Centers, which monitor ash dispersion and issue timely warnings. The International Volcanic Health Hazard Network also offers guidelines on personal protection, emergency planning and ash cleanup.
The long tail of ash
Volcanic ash may fall quietly, but its effects are widespread, persistent and potentially deadly. It poses a chronic threat to health, agriculture, infrastructure and aquatic systems.
Recognizing the risk is a crucial first step to protecting lives. Effective planning and public awareness can further help reduce the damage.

Unmasking the Deception: The $300 Million Fraud Case Surrounding Arizona Athletic Grounds
Randy and Chad Miller face serious fraud charges after allegedly defrauding investors out of $300 million in their failed sports complex, revealing a cautionary tale for investors.

In a tale that intertwines ambition with deceit, the shocking story of Randy and Chad Miller, the father-son duo behind what was once touted as the largest sports and entertainment complex in the United States, has taken a dark turn. Opening the sprawling Bell Bank Park—which boasts an impressive 194 fields and courts—in East Mesa just three years ago, the Millers had big dreams. But now, they find themselves embroiled in a federal indictment that claims they defrauded investors out of nearly $300 million.
A Grand Vision Becomes a Nightmare
The original vision for the sports complex, which has since been rebranded as Arizona Athletic Grounds, was ambitious. Randy Miller, the mastermind behind the project, had long dreamed of creating a hub for sports and entertainment that would attract families, athletes, and fans from across the nation. After years of planning and investment, the facility finally opened its doors, seemingly fulfilling a lifelong dream.
However, dreams of grandeur have turned into a nightmare, as the Millers face serious allegations of using the facility as a front for an elaborate fraud scheme. With the company declaring bankruptcy in 2023—reporting debts of a staggering $366 million—investors and stakeholders are left reeling.
The Allegations: A Web of Fraud and Deceit
According to the federal indictment, Randy and Chad Miller allegedly enriched themselves at the expense of investors, using funds raised from municipal bonds for personal luxuries rather than for the intended purpose of constructing and operating the sports complex. The FBI claims they employed fraudulent documents and misrepresented the financial viability of the project to lure in unsuspecting investors.
From lavish purchases of luxury vehicles to alleged misappropriation of funds for personal expenses, their actions paint a picture of greed and entitlement. Not only did the Millers reportedly pay themselves significantly beyond disclosed salaries, but they also misled investors with false financial projections and forged documentation purporting to show interest from customers.
A Cautionary Tale for Investors
This case serves as a cautionary tale about the complexities of investing in large-scale projects. The Millers poured their aspirations into the Arizona Athletic Grounds but masked disappointing financial realities with misleading projections and falsified documents. The initial feasibility study performed in 2016 indicated the project would generate significantly lower revenues than anticipated—a warning sign that went ignored in pursuit of ambition.
In a staggering twist, the project opened to a far cry from its projected success, generating less than $28 million in its first year compared to the nearly $96 million touted to investors. With bankruptcy filings showing that investors recouped a paltry sum of less than $2.5 million from their $284 million investment, many are left to ponder how their trust could be so easily manipulated.
Legal Ramifications and Future Implications
As the case unfolds, Randy and Chad Miller are facing severe legal consequences, including charges for wire fraud, securities fraud, and aggravated identity theft. If convicted, they could spend decades in prison, a sobering reality for the once-celebrated entrepreneurs. The U.S. Securities and Exchange Commission is also pursuing parallel action, further complicating matters for the Millers.

This incident not only reflects the pitfalls that entrepreneurs can face but also highlights the responsibilities of investors to conduct thorough due diligence before committing funds to any venture. The tale of the Millers serves as a stark reminder of the importance of integrity, transparency, and community trust in business practices.
Conclusion
As this saga continues to unfold, the story of the Arizona Athletic Grounds serves as a reflection on ambition gone awry. It’s a stark reminder that behind every grand vision lies the essential need for honesty and ethical conduct. The community of East Mesa, once hopeful for a thriving sports destination, now faces the challenge of moving forward, learning from the past, and rebuilding trust in local business ventures. We can only hope that the lessons from this cautionary tale resonate not just within the realm of sports and entertainment but across all industries that forge the backbone of our economy.
