What do ferries, gas stoves and home heating systems have in common? Many of them run on natural gas. But what many people don’t know is that natural gas is a health hazard — for families in BC who live beside the LNG-fracking industry that produces it, for people who burn it in their homes, and for the climate change that is devastating our planet. As doctors and nurses who care for patients and communities across western Canada, we say: it's time we talk about the health effects of natural gas.
Natural gas is a flammable mixture of hydrocarbon gases mostly composed of methane. However, despite being branded as "natural," natural gas is a fossil fuel like coal, oil, and gasoline. It fills the air with harmful greenhouse gases and pollutants when it burns.
Liquefied natural gas, or LNG, is natural gas that has been cooled and compressed to around negative 160 degrees Celsius for transportation. Canada's largest natural gas reserves are located in northeast British Columbia, deep underground. These reserves are fuelling an expanding LNG industry.
To access gas deposits in BC, fossil fuel companies must use a polluting and water-intensive technique called hydraulic fracturing, commonly known as "fracking," to crack the earth open.
There are more than 20,000 fracking wells scattered across northeastern BC, with more wells being drilled every day. These wells destroy forests and farmland. In fact, fracking-related access roads, well pads, water hubs, pipelines, compressor stations, gas plants, and waste disposal in BC cover five times as much land as Alberta tar sands mines.
The process of fracking is deeply polluting. It can poison the air, contaminate the water and soil, and imperil the lives of those living close by the well.
Findings from more than 1,700 studies, articles, and reports show that fracking activities are associated with a host of health problems including birth defects, cancer and asthma. It is no wonder that fracking is banned in several countries (including France, Germany, and the UK) and provinces (including Quebec and New Brunswick).
Harmful gases like benzene and radon are released from the rock by fracking. Cough, shortness of breath, and wheezing are therefore some of the most common complaints from residents living near fracked wells. Similarly, the toxic brew of water and chemicals in frack fluid that returns to the surface is often stored in open pits, releasing volatile organic compounds (VOCs) into the air that can cause asthma, COPD, cancer, and other severe illnesses.
Each fracking well can pollute over 10 million litres of fresh water, most of which is permanently removed from the water cycle. Harmful chemicals including BTEX (benzene, toluene, ethylbenzene, xylene) and heavy metals like mercury and lead have contaminated agricultural soils near fracking operations. Multiple chemicals in produced water are known to have carcinogenic and endocrine disrupting properties, and contain radioactive materials.
Fracking chemicals are harmful to pregnant women and their developing babies. Researchers have found endocrine-disrupting chemicals in surface waters near wastewater disposal sites, and evidence for increased levels of a degradation product of the carcinogen benzene in the urine of pregnant women. There is also strong evidence linking fracking to preterm labour and low-birth-weight babies.
BC's Peace region experiences roughly 1,500 small earthquakes a year, most of which are connected to fracking operations. In this part of BC, a total of 439 earthquakes up to 4.6 magnitude were associated with fracking between 2013 and 2019. Fracking can cause earthquakes in two ways:
(1) High-pressure fluid injection during hydraulic fracturing
(2) High-pressure disposal of fracking wastewater (or "produced water") into abandoned wells.
Natural-gas kitchen appliances pollute your home with nitrogen dioxide (NO2), an air contaminant. If you cook with gas and have a child with asthma, your stovetop could be exacerbating their attacks.
In 2015, following an extensive review of the science, Health Canada issued new indoor NO2 safe exposure limits. These limits remain among the strictest in the world. Unfortunately, Health Canada says that most existing Canadian gas ranges do not meet its long-term NO2 exposure standard.
Natural gas furnaces, water heaters, clothes dryers, fireplaces, and cooking appliances also generate a staggering amount of British Columbia's climate pollution. Read more about this problem and its solutions at switchitupbc.ca.
Methane, the main component of natural gas, is a potent greenhouse gas with 86 times the heating impact of carbon dioxide over a 20-year span—in other words, a super pollutant that has enormous short-term impacts on our climate.
While natural gas itself is less carbon intensive than coal when burned, methane leaks at every stage of its extraction and processing. If enough methane leaks during its production, its greenhouse gas advantages are wiped out. Recent studies suggest that methane leakage is double what the government previously estimated, bad enough to make natural gas the climate-heating equivalent of coal—and definitely not a transition fuel. In fact, atmospheric methane levels are higher than they have been in 800,000 years. This is why scientists say controlling methane is one of our best bets for reducing global heating now.
Despite a commitment to a 40% greenhouse gas emission reduction by 2030 and a promise to achieve net-zero by 2050, between 2020–2021 BC’s government spent $1.3 billion on fossil fuel subsidies — 8.3 percent more than the previous year. Rather than decrease over time, these subsidies are estimated to surpass $1.8 billion in 2023-24—more than triple what the previous government spent in 2016-17. It is therefore no surprise that BC’s carbon emissions continue to rise each year.
These ongoing handouts will make it almost impossible for BC to hit its legislated greenhouse gas reduction targets by 2050.
To avoid runaway climate heating, with more droughts, wildfires, floods and harms to human health, fracking and LNG must be scaled back, starting now. We need to have a frank, province-wide conversation about our shared future. Fortunately, some businesses and communities in the north are already well on their way to building a sustainable and healthy economy. We need to bring together all stakeholders — government, Indigenous Nations, health organizations, citizen groups, scientists and business — to work out how we all will thrive in a future without fracking or LNG.
As doctors and nurses working in British Columbia, we ask that the following changes be implemented to guarantee a healthy and sustainable future for our province.
Because natural gas extraction harms the health of people living near fracking wells and intensifies the climate crisis, the BC government should stop all new fracking development.
Natural gas hook-ups should be banned in all new buildings by 2023, with buildings in the north given until 2025 to comply. We must invest in retraining programs for workers to build affordable zero emissions buildings, and retrofit all existing buildings for zero emissions.
Support must be provided to workers and Indigenous communities impacted by LNG production to transition to a clean-energy economy, including financial support for retraining, and a guarantee of good, zero emissions jobs.
The provincial governments must end all fossil fuel subsidies as defined by the World Trade Organization, including direct spending, tax breaks, transfer of risk, and public finance.
Implementing these changes won't be easy. We are up against a massive fossil fuel industry that spends millions each year lobbying our provincial and federal governments. But together we can make a difference in fighting fracking and climate change. Sign our letter to the BC government below and stay updated on our campaign and ways to help out.
