Comox Valley Students ‘Stand up, Fight Back’ for Climate Action

By Gavin MacRae

A jovial yet determined crowd of student strikers and adult supporters over 250 strong marched through downtown Courtenay Friday, to demand action on climate change.

The protest started with a rally at Courtenay City Hall.

The crowd cheered as speakers said it was time to “stand up and fight back” against fossil fuel interests and insufficient government action.

“We are here today under a unified cause to protest climate change,” said Nalan Goosen, a co-organizer of the event.

Speaking through a megaphone, Goosen said investments in the tar sands and other fossil fuel infrastructure make Canadian banks culpable for climate change.

To showcase this, the demonstration traced a serpentine route through the downtown to pause and protest at CIBC, Bank of Montreal, and Scotia Bank.

Outside CIBC the crowd chanted, “No more coal, no more oil, keep the carbon in the soil!”

At Bank of Montreal the rallying cry was, “What do we want? Climate Action! When do we want it? Now!”

Finally, the Scotia Bank received, “Corporate greed we must fight, polluting earth is not a right!”

The crowd also made a stop at the office of MLA Ronna-Rae Leonard, where she and MP Gord Johns spoke with the demonstrators.
Both politicians gave short impromptu speeches on the importance of protecting the environment.

Students put questions to Leonard and Johns about increasing climate education in the school system, protecting old-growth forest and marine areas and fighting the Trans Mountain pipeline.

The answers met with some applause, and Goosen said he was hopeful Leonard would bring the demonstrators’ concerns about old-growth logging to Doug Donaldson, BC’s Minister of Forests. Goosen was also hopeful Johns would echo the students’ concern over the climate crisis in Ottawa.

The protest ended with a return to City Hall.

Students said all but two schools in Comox and Courtenay were represented among the protesters.

“The turnout was amazing,” said Mackai Sharp, a co-organizer of the protest. “The last two events had under 35 people.”

Sharp and Goosen are leaders of the Comox Valley-based Youth Environmental Action, which planned the protest. The group has a separate arm for adults named Adult Allies for Youth Environmental Action.

”This will not be our last protest, said Goosen. “We don’t have very long to solve the climate crisis, so this movement of youth empowerment is essential to our health and survival.”

How ocean acidification is reshaping marine food webs

By Gavin MacRae

The depths of the ocean are slowing climate change, but at a cost. Seawater acidity is increasing as the oceans absorb carbon dioxide from fossil fuels.

Average surface ocean pH is now 30 percent more acidic than in pre-industrial times. In a business-as-usual scenario, by 2100, ocean water could be over one-and-a-half times more acidic.

The effects of ocean acidification can be grouped into “known knowns, known unknowns, and unknown unknowns,” says Wiley Evans, a chemical oceanographer leading ocean acidification research for the Hakai Institute. Evans is riffing on an old Donald Rumsfeld quote because, although the underlying chemistry is straightforward, the full consequences of ocean acidification are uncharted.

“A lot of what is unknown is at the species level,” he says. Only a handful of organisms have been thoroughly tested for their response to rising acidity. “And then there’s the ecosystem response – how impacts on one organism is going to affect the whole food web, and the ecosystems that those organisms reside in. So pretty quickly it snowballs into a lot of unknowns.”

Biologists, chemical and physical oceanographers, geneticists, and other experts are now working together to investigate these unknowns. Research into ocean carbonate chemistry has been done since the 1970s, but only in 2003 did the term ocean acidification come into use. It’s now an “exploding field,” says Evans. “It really is interdisciplinary, it relies on the physics and the biology, and the ecosystem level [research], and so ecologists and modellers and everyone is really working together to try and understand the breadth of the problem.”

The dynamic ocean environment makes the research complex. “The pH of the ocean changes constantly,” says Mark Spalding, president of the Ocean Foundation, an environmental organization based in Washington, DC. “It fluctuates daily, it fluctuates seasonally, it fluctuates with El Niño events, it fluctuates when you have an upwelling from the deep ocean.”

Ocean acidity also differs by location. Natural factors dominate the exchange of atmospheric carbon dioxide into the ocean, but just as with atmospheric carbon, additional emissions have tipped the scales.

Ocean acidification also has to be disentangled from other co-occurring climate change stressors such as warming water and deoxygenation. Each effect is worrying on its own; combined, these multiple stressors are greater than the sum of their parts.

Despite this complexity, ocean acidification is caused by simple chemical reactions.

“It’s pretty much just like high school level chemistry,” says Evans. “As you increase carbon dioxide in the atmosphere, it’s not all going to stay there, it’s going to want to move into an area of lower concentration, and CO2 gas will dissolve into seawater.”

When carbon dioxide in the air reacts with seawater it forms carbonic acid. This carbonic acid then breaks down into bicarbonate and a hydrogen ion.

The pH of a solution (how acidic or basic it is) is determined by the concentration of hydrogen ions – the more hydrogen ions, the more acidic. Ocean water hasn’t become an actual acid, but its alkalinity is declining.

Surplus hydrogen ions then bond with carbonate ions also found in seawater to form more bicarbonate.

Impact on shellfish

Many types of shelled organisms build their shells by combining carbonate ions with calcium to form calcium carbonate. But because some of the carbonate ions have already bonded with hydrogen ions, shellfish, mullusks, corals, and other shelled creatures face a scarcity of carbonate ions with which to build their shells.

“The first time we really noticed this was happening was with oysters in the Pacific Northwest of the United States,” says Spalding. “The largest oyster farming business in the world … saw a dramatic loss in production as a result of some acidic events.”

Since then, ocean acidification has become an ongoing concern for shellfish farmers, particularly for operations in developing countries lacking the technology to monitor and react to pH changes.

Shellfish are most vulnerable to acidity as tiny, newly hatched larvae, when they have to exert a tremendous amount of energy to build their first shell. The scarcity of carbonate can either prove fatal, or the shellfish “end up with very deformed shells and thinner shells, and become more susceptible to predators,” says Spalding.

The same threat applies to urchins, snails, seastars, and corals, although the exact chemical process can vary. In a study conducted near a volcanic seep which emulated future CO2 levels, “triton shell” sea snails were found to have their shell thickness halved, and in some cases so dissolved their body tissue was exposed.

The most urgent example of shell corrosion may be to creatures near the base of the food chain called pteropods, commonly known as sea butterflies.

“They look like minuscule snails with wings,” says Spalding, “and they’re having a very, very hard time forming their shells.”

Field observations have recently confirmed that pteropod shells in an area of increased acidity in the Gulf of Alaska are dissolving.

“If the ocean continues to have its chemistry change … we could have a rippling effect where the food resource for other animals in the ocean, and up the food chain, has a rippling collapse,” says Spalding.

For corals, ocean acidification is only one ingredient: “warmer waters, thanks to climate change, nutrient pollution, oxygen deprivation, and then you add in ocean acidification, and you’ve got a horrible recipe for collapse of coral systems,” says Spalding. “The current predictions are losses of 90 percent or more of our coral reefs by 2030.”

At rock bottom on the marine food chain are diatoms – microscopic, single-celled algaes encased in shells of transparent silica. They live near the surface of the ocean, transforming sunlight to sugars via photosynthesis. When they die, a percentage fall to the ocean floor, sequestering carbon.

Iron uptake in diatoms

Diatoms are immensely important to the marine food web, and to all life on earth – cycling about 20 percent of the oxygen we breathe. Research published in Nature in 2018 suggests ocean acidification could threaten diatom populations – but not by hindering shell formation. Increased acidity, for an unknown reason, prevents the uptake of iron that diatoms need to proliferate.

Diatom numbers are already in decline, and rising surface ocean temperatures are suspected. A crash in diatom populations could cripple the ocean’s ability to cycle carbon dioxide, accelerating further climate change.

Fish are not off the hook in the struggle to adapt to a more acidic environment, either. Tests conducted in the National Oceanic and Atmospheric Administration’s Fisheries research lab showed salmon exposed to future pH levels were less responsive to the smell of salmon skin extract, which would normally warn the fish of a predator attack and prompt them to hide or flee.

Testing of the salmons’ nose and brain tissue indicated that the fish could still detect the scent, but were not interpreting and acting on the trigger.

Other behaviours relying on scent – reproduction, navigation, and finding food – are also likely affected. Similar research has shown elevated CO2 concentrations to blunt prey detection in sharks, and affect the ability of reef fish to discern healthy reef habitat.

Some species are predicted to benefit from ocean acidification, but this isn’t necessarily a good thing. Research from the Canary Islands suggests the algae Vicicitus globosus, found from temperate regions to the tropics, will thrive in rising CO2 levels. Toxic blooms of V.globosus are already known to cause fish kills, and now, researchers say, “may pose an emergent threat to coastal communities, aquaculture and fisheries.”

Krill probably OK

Other organisms may shrug off ocean acidification altogether. Krill are small crustaceans found in all oceans, and an essential food source for marine mammals and seabirds in the Southern Ocean.

In a 2018 study published in Communications Biology, adult Antarctic krill, in acidity simulating near-future conditions, were able to go about their business undisturbed. The krill’s resilience is attributed to a special structure in their gills able to balance body fluid pH. Krill eggs and embryos, however, don’t have this ability, so the results are not definitive.

The sum of these effects (and several more) put future food security in doubt. Evans says that the capacity of the oceans to feed us could be threatened when we need it most.

“We need to divest from cattle production, as they’re major contributors to CO2 emissions, and we’ll be relying more on aquaculture and fishing … and so we essentially could be in a bottleneck, where some of these species that we’re going to try and grow are going to have difficulty,” he said.

Ocean acidification may have caused events in the earth’s history that go well beyond concerns over food security. Research published in Science in 2015 puts forward the theory that modern day ocean acidification has chilling parallels with the Permo-Triassic mass extinction, also known by its cheerful nickname, the Great Dying.

Around 252 million years ago, volcanoes belched huge quantities of carbon dioxide into the atmosphere over tens-of-thousands of years. This in turn triggered a spike in ocean acidity that the research suggests killed up to 96% of marine life. During the Great Dying, CO2 levels in the ocean shot up about as quickly as they are today.

“Climate change is physics, and ocean acidification is chemistry,” says Spalding, “but they’re both the same carbon dioxide molecules. Our ocean is our biggest sink for our carbon emissions, but there are limits. It can only take so much.”

WHAT IS OCEAN ACIDIFICATION?

For more than 200 years, or since the industrial revolution, the concentration of carbon dioxide (CO2) in the atmosphere has increased due to the burning of fossil fuels and land use change. The ocean absorbs about 30 percent of the CO2 that is released in the atmosphere, and as levels of atmospheric CO2 increase, so do the levels in the ocean.

When CO2 is absorbed by seawater, a series of chemical reactions occur resulting in the increased concentration of hydrogen ions. This increase causes the seawater to become more acidic and causes carbonate ions to be relatively less abundant.

Carbonate ions are an important building block of structures such as sea shells and coral skeletons. Decreases in carbonate ions can make building and maintaining shells and other calcium carbonate structures difficult for calcifying organisms such as oysters, clams, sea urchins, shallow water corals, deep sea corals, and calcareous plankton.

These changes in ocean chemistry can affect the behavior of non-calcifying organisms as well. Certain fish’s ability to detect predators is decreased in more acidic waters. When these organisms are at risk, the entire food web may also be at risk.

Ocean acidification is affecting the entire world’s oceans, including coastal estuaries and waterways. Many economies are dependent on fish and shellfish and people worldwide rely on food from the ocean as their primary source of protein.

Comox Valley man working AVICC to ban groundwater extraction

By Gavin MacRae

Vancouver Island Groundwater Rights Update Water rights advocate Bruce Gibbons is on a mission to end licensing of groundwater extraction for bottled water on Vancouver Island. And if that goes well, for all of BC.

Gibbons is burning shoe leather and working the phone to encourage all 53 districts and municipalities in the Association of Vancouver Island Coastal Communities (AVICC) to support an upcoming motion requesting the provincial government stop issuing well licenses to bottle water. If the motion passes, it heads to a province-wide vote at the Union of British Columbia Municipalities.

Gibbons said preventing groundwater bottling is a “no brainer” for many coastal communities, and several town councils have voted to support the AVICC motion on-the-spot after listening to his presentation.

The other half of Gibbons’ two-pronged approach is to ensure that there is a back-up if the AVICC motion fails. Gibbons discovered most towns need to amend the language of their bylaws if they want to prevent commercial bottling of groundwater, and he’s encouraging them
to do so

“When people wrote bylaws for their communities, they weren’t thinking of bottling water, so in most cases it’s not an actual conscious decision to allow it or not allow it,” he said. “[Communities] look at their bylaws and say ‘well it looks like if it came down to a decision, this
particular bylaw would allow it because it doesn’t expressly prohibit it,’ so they’re finding themselves in a position where they need to revise their bylaws to expressly prohibit bottled water.”

According to Gibbons, a dozen AVICC communities now have bylaws on the books that specifically forbid bottling groundwater. Twenty five AVICC communities have bylaws that doallow groundwater bottling (several of these are working to amend their bylaws). The bylaw
status of the remaining communities is unknown.

AVICC communities have been largely supportive of Gibbons urging a review of old bylaws. The exception has been Langford, where Gibbons said planning officials were uncooperative and appeared confused by his request.

“It was just a really weird experience with them. It wasn’t so much that they didn’t believe in what I was doing. They just didn’t get it.”
He’s shaken off the minor failure and said regardless which way the AVICC vote goes, water rights in BC are advancing, and his campaign is worthwhile.

“When you get involved in something like this, you realize how many people there are who really devote a lot of time and energy to protecting our environment and the world we live in. It takes a lot of time and energy, but it’s a very positive thing.”

WHAT IS THE ECOLOGICAL ACCOUNTING PROCESS (EAP)?

Ecological Accounting Process — “The EAP approach begins by first recognizing the importance of a stream in a natural state and then asking: how can we maintain those ecological values while allowing the stream to be used for drainage,” says Jim Dumont, Engineering Applications Authority with the Partnership for Water Sustainability in BC.

Comox Valley hears “Voices from the Sacrifice Zone’

By Gavin MacRae

ITwas a long rap sheet, but speakers from the Canadian Association of Physicians for the Environment detailed the dangers of fracking to people in the Peace region of BC, this Sunday at the Florence Filberg Lounge.

Voices from the Sacrifice Zone was hosted by the Watershed Sentinel.

Frenetic natural gas development using fracking – an extraction procedure where high-pressure water, sand, and a cocktail of proprietary (and not publicly known) chemicals are pumped into gas wells to stimulate production – have rural residents of the Peace region “enmeshed like a spider’s web,” said event moderator Dr. Warren Bell.

The impacts of fracking are hard to miss: round-the-clock flaring of excess gas, open-pit wastewater ponds the size of small lakes, and the constant drone of diesel-powered equipment. Other effects are insidious, such as increased rates of terminal cancers and lung diseases.

Karen Leven, an environmental scientist from Dawson Creek, opened the event. She said 28,000 wells have been drilled in the Peace region since 2005. Future LNG capacity in BC is expected to prompt 100,000 more wells, and 85% of them will rely on fracking.

Leven described a region under siege from fracking activity, with few controls on the pace of development, and environmental recommendations ignored. People are “basically totally powerless” to control or stop fracking in their neighbourhoods, said Leven.

Fracking degrades surface and groundwater and air quality, impacts fish and wildlife, spikes methane emissions, and puts residents at risk of gas explosions and earthquakes, she said.

Leven said the disparity between environmental regulations in the mining industry versus oil and gas is “night and day.”

Retention ponds for mining operations must be double-lined, and spills are closely monitored and reported. Retention ponds for fracking wastewater are not required to be lined, said Leven. The wastewater is allowed to percolate into the ground. (A 2016 study published in Nature found fracking fluid can contain arsenic, benzene, formaldehyde, lead, mercury, and scores of other chemicals).

“The industry needs to prove to the public that they are not causing harm”

Gas has been touted as green energy which would help to reduce greenhouse gas emissions, said Levin, but when the effects of escaped methane emissions are factored, natural gas is a potent cause of climate change, disguised as a solution.

Married couple Pat and Jim Strasky operate a grain farm in the region. The view from their their farmhouse is dominated by multiple fracking sites, often flaring excess gas. An unlined, 70-acre fracking wastewater pond sits nearby, with a mountainous earth backdrop from its excavation. Jim struggles to move farming equipment down roads worn to muddy, rutted tracks from oil and gas trucks that can require 5000 trips per frack. Complaints about the road degradation are ignored.

“If there’s a frack on, there will be 100 trucks in 24 hours,” said Pat. “They’ll go by the house, day and night.”

During fracking, large-diameter water hoses can stretch for kilometres through culverts, in ditches, and over roads, immobilizing farming equipment.

“It’s incredible, the amount of material they pump down those holes, between the water and the frack sand, and the chemicals to got with it.”

The land for wellpads and other infrastructure has been pruned from the Agricultural Land Reserve, and Jim figured about 12% of their farmland had reduced yield.

Dr. Ulrike Meyer, a physician in Dawson Creek, talked about the health risks of living in the Sacrifice Zone. Cancer rates and respiratory conditions in the region are elevated – including pulmonary fibrosis, that Meyer suspects is linked to the silica from fracking fluid. Meyer said fracking can also bring naturally occurring radioactive material up from deep below the ground, but the link between the radioactive material and cancer rates is to-date unproven.

Assigning definitive blame to fracking is elusive because studies and data are scarce, said Meyer, but individual case studies are compelling.

One of her patients suffered from fainting spells and cognitive decline. Near his house sat a fracking wastewater holding tank the size of a swimming pool. In winter, propane heaters prevented the water from freezing, and steam would waft off the tank toward his house. When the tank was eventually removed, his health quickly rebounded. The current regulated back-set for wastewater tanks is 100m from a residence, and Meyer called on that to be extended to 1600m.

Testing of pregnant woman in Dawson Creek showed levels of benzene, a carcinogen and known endocrine disruptor, three times higher than normal. Levels of barium, strontium, manganese, and aluminum were also “way higher than the rest of the Canadian population,” said Meyer. A study by UBC showed the same metals are in the region’s water at elevated levels, and contamination from fracking is suspected.

Another effect of fracking are “boomtown” problems – lower education levels, and increased drug use, sexually transmitted diseases, and crime.

“The industry needs to prove to the public that they are not causing harm,” said Meyer. She called for a full public inquiry on the effects of fracking to human health, drinking water, and the environment.

The event ended on an upbeat note with Don Pettit, a renewable energy expert in the Peace Region, speaking on how to move past fossil fuels and the problems they create. “We are now in the midst of the most dramatic and important energy transition in human history. The shift to the new clean energies of wind, solar, conservation, and energy efficiency provides clear answers to our global problems,” said Pettit.

“We know what the problems are, we know how to fix them, and the tools to do so are in our hands.”

5 REASONS TO
BAN FRACKING

1 — Fracking threatens water sources. A fracking project requires anywhere from 10 million to 90 million litres of water per project, the equivalent of roughly 4 to 36 Olympic-sized swimming pools. There is no method to safely dispose of fracking wastewater. The injection of fracking wastewater into the ground has been linked to earthquakes.

2 — Fracking makes climate change worse. Some industry and government officials are promoting fracked natural gas as a “clean, green fuel,” but studies show that this type of gas can produce as much greenhouse gas emissions as coal.

3 — Fracking puts public health at risk. Fracking companies are not required to disclose how many – or even what kinds – of chemicals they use. Studies have shown that many of the chemicals (the ones we do know about) cause serious health problems such as cancer or organ damage.

4 — We need green jobs. Fracking is a threat to farming, tourism and other sustainable industries. Rather than continuing to frack for natural gas or oil, we should look for sustainable solutions to transition off of fossil fuels.

5 — Fracking opens the door to other mega projects. Fracking projects can lead to a network of fracked gas pipelines, Liquefied Natural Gas (LNG) terminals, export projects, and LNG super tankers that impact our watersheds and climate and the health and safety of our communities.

Strathcona groundwater motion headed to AVICC vote

Strathcona groundwater motion headed to AVICC vote

By Gavin MacRae

The Strathcona Regional District has unanimously passed a motion requesting the province cease licensing groundwater for commercial water bottling and bulk water exports.

Currently, the motion applies only to the Strathcona Regional District, but will be heard again at an April meeting of the Association of Vancouver Island and Coastal Communities (AVICC).

If it is passed there, the motion will become island-wide, and again move upward to be considered as a unified request by the Union of British Columbia Municipalities. There is potential for all BC municipalities and districts to send an unambiguous message that would “put huge pressure on the provincial government to change the Water Sustainability Act (WSA),” said Brenda Leigh, Strathcona Regional District Area D director, and architect of the board’s Jan. 24 motion.

“There’s 29 regional districts in British Columbia, and a lot of them have been impacted by corporate extraction of their water supply,” said Leigh. “This is very important because the commodification of water in Canada means that we’re putting our water sources at risk.”

A 2018 struggle between the Ministry of Forests, Lands, Natural Resource and Rural Development (FLNRORD), and the Comox Valley Regional District (CVRD) highlighted the friction between regional districts and the BC government over groundwater extraction for profit. The dispute began when FLNRORD approved a license for the commercial sale of groundwater, without public notification and against the wishes of the CVRD and K’omoks First Nation. Public opposition to the license was formidable, and the CVRD ultimately denied a zoning amendment necessary for the water to be processed, effectively rendering the license unusable.

Leigh said her motion is rooted in general principle, and not in reaction to the CVRD dispute. 

Changes to the WSA would negate the need for district-level efforts to control commercial water extraction with zoning decisions, said Leigh. “First things first – we need to get the province on our side, and make sure they’re protecting our water. They have the power to do that.”

Leigh was critical of the “first in time, first in right” principle guiding groundwater licensing in BC. “First in time, first in right, is about giving licenses to corporations to bottle the water, or sell it by bulk, and that is putting our aquifers at risk unless the local government knows how
it’s going to impact their citizens,” she said.

Some areas in Leigh’s district rely totally on groundwater. In recent summers, drought conditions in August have forced the district to tap emergency reservoirs. She anticipates climate change will exacerbate the problem in the future.

“It’s sort of a perfect storm,” she said.

GROUNDWATER: OVERUSE AND DEPLETION

Groundwater is the largest source of usable, fresh water in the world. In many parts of the world, especially where surface water supplies are not available, domestic, agricultural, and industrial water needs can only be met by using the water beneath the ground.

The U.S. Geological Survey compares the water stored in the ground to money kept in a bank account. If the money is withdrawn at a faster rate than new money is deposited, there will eventually be account-supply problems. Pumping water out of the ground at a faster rate than it is replenished over the long-term causes similar problems.

Groundwater depletion is primarily caused by sustained groundwater pumping. Some of the negative effects of groundwater depletion:

Lowering of the Water Table
Excessive pumping can lower the groundwater table, and cause wells to no longer be able to reach groundwater.

Increased Costs
As the water table lowers, the water must be pumped farther to reach the surface, using more energy. In extreme cases, using such a well can be cost prohibitive.

Reduced Surface Water Supplies
Groundwater and surface water are connected. When groundwater is overused, the lakes, streams, and rivers connected to groundwater can also have their supply diminished.

Land Subsidence
Land subsidence occurs when there is a loss of support below ground. This is most often caused by human activities, mainly from the overuse of groundwater, when the soil collapses, compacts, and drops.

Water Quality Concerns
Excessive pumping in coastal areas can cause saltwater to move inland and upward, resulting in saltwater contamination of the water supply.
