Humans are using around 129 billion masks per month

We know that personal protective equipment (PPE) such as masks and face shields is important in protecting people against COVID-19.

April 22, 2020

But who’s protecting Mother Earth?

According to a study by the Environmental Science & Technology journal, humans around the globe are using approximately 129 billion disposable face masks and 65 billion plastic gloves every month.

And many of those masks have become litter in streets, beaches and oceans.

That waste is cause for concern for environmentalists like Rebecca Prince-Ruiz.

“There’s been an extraordinary rise in single-use plastics used in PPE,” said Prince-Ruiz, founder and executive director of Plastic Free Foundation, an organization aimed at limiting single-use plastics across the world.

“It’s the issue on top of everyone’s mind.”

Disposable masks are extremely important for front-line workers such as doctors and nurses.

Stopping their use isn’t an option.

But there are small things everyone can do to reduce waste, Prince-Ruiz said, such as wearing reusable masks.

Kids can also encourage adults to reduce their use of plastic gloves.

There are also companies finding creative solutions to this environmental issue. (Continued: CBC Kids)

The future of our watershed is far from assured

Look, it’s another non-COVID-19 editorial! That’s right, we wanted to give you a break from nonstop pandemic news and commentary. We know that can get heavy.

November 26, 2019

So instead, let’s talk about the state of Cootes Paradise, Chedoke Creek and Hamilton’s watershed in general. That’s bound to lighten your mood. Not.

A new report from the City of Hamilton says no special cleanup or monitoring of the Cootes Paradise marsh is called for as a result of the now infamous 24-billion-litre sewage leak known as Sewergate.

Before you utter a collective sigh of relief, let’s be clear: That doesn’t mean the protected marsh area is fine. It’s not. And common sense suggests the extra billions of litres of sewage leaked over more than four years into Chedoke Creek, which drains into the marsh, did not help matters. 

December 7, 2019

According to a report from The Spectator’s Matthew Van Dongen, the report by SLR Consulting concludes there was no lasting damage to the marsh from the sewage spill, but it also observes that it’s hard to know where any specific piece of pollution is coming from, because there are so many sources. Well, that’s a relief.

Hamilton Coun. Maureen Wilson rightfully referred to the situation as a “damning indictment” of how the city has treated Cootes through history, allowing it to become dirty nearly beyond redemption prior to efforts in the last two decades to reclaim the marsh.

Progress has certainly been made, but the reality is that Cootes remains painfully polluted, not only by sewage but also by leachate from old landfill sites and toxic-run-off from highways, parking lots and other sources.

November 27, 2019

Back to the report for a bit. The consultant’s view is not necessarily and final word. The Royal Botanical Gardens, which owns the marsh, is studying the report, and while there is no final determination, there are hints the RBG may not agree with the report’s findings. The RBG’s Nick Kondrat told Van Dongen: “ … our initial assessment is that we strongly believe that additional analysis is required to evaluate the severity of the damage” from the spill.

The provincial Ministry of Environment, Conservation and Parks has also yet to pass judgment, and it may differ from the consultant when it comes. It will also determine whether any aspect of the spill broke the law. If it did, charges against the city could follow.

The Hamilton Spectator

But suppose the provincial ministry report doesn’t amount to much. And suppose the RBG’s findings and recommendations aren’t conclusive. Where does that leave us? 

As much as we like to use the Sewergate label — The Spec did coin the phrase and break the story, after all — the spill and its fallout are not the most important issue at hand. What matters more is where we go from here. 

Are we satisfied with the status quo, with ongoing cleanup efforts that have delivered laudable but not conclusive results?

Cootes is still receiving pollution from so many sources pollutants can’t be traced to any one source. Chedoke Creek’s bed is layered with contaminated sludge. Major weather events, of which we are having more and more, still result in sewage holding tank overflow that leaks into the marsh, harbour and lake. (Hamilton Spectator Editorial)

Single-use plastic is having a resurgence during the pandemic

For those seeking silver linings in the ongoing coronavirus pandemic, the notable drop-off in air pollution has been a recurring bright spot. But while theskies might be clearing up (at least temporarily) while millions of people shelter in place, humans are poisoning the planet in other ways. Increased demand for medical supplies, households stocking up on tons of goods, and fears over COVID-19 spreading across different surfaces has single-use plastics on the rise — and as Wired reports, we’re running out of places to put it.

March 12, 2019

As more plastic waste pours in, the already overwhelmed recycling system is at risk of getting completely buried. Prior to coronavirus, many recycling companies were already struggling to deal with the more than 300 million tons of plastic discarded every year — nearly 50 percent of which is single-use. According to the Earth Institute at Columbia University, only about 10 percent of all discarded plastic products in the United States actually get recycled — a fact the plastic industry knew for years while touting recycling programs that would never be viable. Nearly 75 percent ends up in landfills, where it can sit and erode for hundreds of years, releasing carbon dioxide as it degrades and often making its way into waterways and oceans. It’s likely that as the country produces more plastic waste in this time of crisis, even more will be heading to landfills, as the already inundated recycling firms slow their operations. “Many recyclers, because of health and safety concerns, are also stopping the service,” Tom Szaky, CEO of recycling company TerraCycle, told Wired. “Recycling — that’s been in sort of a crash — is now getting even worse.”

April 24, 2018

Those slowdowns are happening in tandem with a resurgence in single-use plastics. This is happening for a number of reasons, both out of necessity and potentially unfounded fears. Plastic bags have made a comeback during thecoronavirus crisis due to concerns that reusable bags may carry the virus. A number of states and cities have reversed plastic bag bans and some have even instituted restrictions on reusable totes. While it is known that coronavirus can survive longer on certain surfaces, there doesn’t appear to be any evidence that the virus is more viable on a cloth tote than a plastic bag, particularly if the bag is washed after use — though the plastic bag is likely to be discarded after one use, limiting additional exposure. With people worried that the virus can be transmitted through a number of surfaces, the demand for packaged goods is on the rise as well. According to FoodNavigator, demand for packaged goods has skyrocketed in Europe by as much as 111 percent for some items as compared to the previous year.

There is also the fact that the price of oil has dropped dramatically, which makes producing plastic goods cheaper than usual — and they aren’t all that expensive to begin with. Plastics are made from oil, and when the price of oil drops far enough, it can result in it actually being cheaper to produce new plastic products than recycle old ones. And when the demand for recycled goods disappears, more plastic ends up in landfills, slowly eroding and polluting the planet.

Plastic waste doesn’t have the same effect as something like air pollution — we don’t immediately see the damage as it occurs. But the change in our consumption habits will be immediately felt at the landfills that are already being overrun. It will be felt by oceans that are already at risk of having more pieces of plastic than fish by 2050. Even the short burst of uptick in plastic waste could cause significant disruption to the waste and recycling ecosystems. According to Waste Dive, dozens of cities and counties across the country have suspended recycling programs entirely. Rachel Meidl, a fellow at Rice University’s Baker Institute, told Wired, “materials that would normally find its way to recyclers are being channeled to landfills and incinerators.” So before touting that “we are the virus” meme and spouting off to your friends about how the Earth is healing while we’re all trapped indoors, remember that there are a lot of ways we can hurt the planet without ever leaving our couches.

Hamilton city council, staff have kept a 24-billion litre sewage spill secret

A confidential city report shows councillors have known since January that 24 billion litres of untreated sewage escaped undetected over a four-year period from a massive sewer overflow tank into Chedoke Creek, which runs along Highway 403 into Cootes Paradise.

November 23, 2019

The watery sewage — enough to fill 10,000 Olympic-sized swimming pools, or an area of 12 square kilometres to a depth of two metres — seeped out of the tank because a gate had been left partially open for more than four years.

The confidential report to council on Jan. 16, along with a second one on Sept. 4, show city staff have been recommending that details of the spill be kept secret from the public as long as possible because of potential legal action the city could face.

The two reports, obtained by The Hamilton Spectator, state Ontario’s environment ministry is investigating the massive spill, which could lead to charges.

Neither the remediation work or any fine levied would be covered by the city’s insurance, according to the reports.

The Spectator informed the city it had obtained two confidential reports and submitted a number of questions Wednesday morning to councillor Lloyd Ferguson, chair of the public works committee. Late Wednesday morning, council went in camera to discuss The Spectator’s questions.

Several councillors, including Ferguson, declined to comment when they emerged from the in-camera session.

March 28, 2009

About an hour later, in response to The Spectator’s questions, the city put out a press release acknowledging publicly for the first time that approximately 24 billion litres of watery sewage had been discharged because a gate at the King Street West tank had been left partially open for 4.5 years.

“Hamilton city council takes this matter very seriously and today is sharing additional information that has become available based on the city’s investigations,” the press release stated.

Lynda Lukasik, executive director of Environment Hamilton, said the long-standing discharge from the overflow tank “is shocking.”

“That’s a brutal impact on Cootes Paradise and Hamilton Harbour,” said Lukasik. “Those (overflow) tanks are just a Band-Aid solution.”

“The City of Hamilton better have a good plan going forward to make sure it doesn’t happen again,” she added.

The two confidential reports were prepared jointly by the city’s public works department and the legal and risk management services division of the corporate services department.

The reports state the city was unaware that a bypass gate at the King Street West overflow tank across from the Cathedral of Christ the King had been left partially open from Jan. 28, 2014, until July 18, 2018, allowing untreated sewage to flow into the creek for 1,633 days.

During heavy rainfall, a combined sewer overflow tank captures a mix of rainwater and sewage that would previously have flowed untreated into Cootes Paradise, the harbour or the lake. Once the wet weather subsides, the overflow can be pumped from the tank to the main sewage treatment plant at Woodward Avenue. (Hamilton Spectator)

Study sheds light on human consumption of microplastics

A study from the University of Victoria has for the first time compiled research on microplastics to try to estimate just how much people are consuming.

June 1, 2019

Microplastics are pieces of plastic that are just under five millimetres in diameter — or smaller than the size of a sesame seed — that come from the degradation of larger plastic products or the shedding of particles from water bottles, plastic packaging and synthetic clothes.

Garth Covernton, a PhD candidate at University of Victoria’s department of biology, said his team looked at 26 papers assessing the amount of microplastics found in individual food items.

May 2, 2018

The study found that a person’s average microplastic consumption — based on those food items previously analyzed — would likely be somewhere between 70,000 and 121,000 particles per year. While younger girls were at the lower end of the spectrum, adult men were at the high end.

People who consume a lot of bottled water could see that number jump by up to 100,000 particles per year.

The study analyzed the amount of microplastics found in fish, shellfish, sugars, salts, alcohol, water and air, which account for 15 per cent of Americans’ caloric intake.

But the other 85 per cent of what people consume, like beef, poultry, dairy and grains, has still not been examined.

March 6, 2015

Covernton compared the study to early understandings of cigarettes and tobacco: While the numbers they came up with did seem large, they don’t yet know exactly what level of consumption is dangerous.

“We’re at the point where we know microplastics at some dose could be harmful, but we’re not at the point where we can say whether what the average person is encountering is the equivalent of one cigarette in a lifetime, or that chronic exposure, like a pack a day.”

Covernton said the findings demonstrate more work needs to be done to understand how the tiny particles might affect human health. (CBC)
