If you hike to the top of Peterson Creek Park on any given day, more so on a cold one, you’ll see a blanket of yellowish, dirty air draped over the valley.
This is not new or unexpected. The surface inversion well-known to these parts increases the effects of air pollution. Whatever is released into that cold air trapped close to the surface, be it vehicle exhaust, mill emissions, or wood smoke, it all stagnates and makes our breathing air a lot worse than it should be.
There is no clear answer as to what is in the yellow plume. Winter smog is a terrible beast made worse by inversion phenomena, but knowing what we breathe in would be good. You can’t fix something if you don’t know where to start or how complex the issue.
It would be nice to know how much each polluting source adds to that yellowish layer. There is no heads-up information about mill emissions or slash pile burning. That affects some people more than others. It is unsettling to be exposed to air pollution by various industries in or around town, and not know when that will happen. Of course, when it does, people notice, but there is something to be said about habituation. Except that in case of our breathing air, it is not in our benefit at all to accept it as is.
On top of notifications about mill emissions and slash burning, there should be information sessions on how air quality is made worse by the inversion and a low venting index. If psychologically it is easy to shrug off the memory of many socked-in days when a better day comes along, and the valley air looks clean, our bodies react differently, as the perilous effects on health are compounded.
Air pollution is a real enemy to human health, and an increasing body of scientific evidence points to it. Short- and long-term effects of air pollution are real and, for the latter, deadly in many cases. The reluctance to recognize them as such have to do, I am willing to say, with the invisible nature of this threat. Should dirty water pour out of out taps, few if any would want to drink it. The air we breathe should be no different. It is true that industrial pollution accounts for much of the bad air in town. But some of the dirty yellow plume is caused by residential activity, be it driving or wood burning.
City traffic has been increasing over the years and that means an increased volume of exhaust gases. Adding to that is the unnecessary idling. There is no need to idle cars for more than 30 seconds on a cold day. Nor is idling while stopping to chat, or while running into a store for some quick shopping, or to keep warm while waiting. Just more toxic gases.
As for wood smoke, whether from residential use or slash pile burning (an environmentally unsound and health-costly solution for all the logging leftovers,) it tends to linger for a long time, which is exactly why in areas where inversion is present wood burning should be reconsidered. A recent study by a team at McGill University concluded that wood smoke increases the risk of heart attack in people over 65 by 19 percent. Residential wood heat accounts for 15 percent of PM2.5 in British Columbia, likely higher in areas like Kamloops where inversion is present.
Wood smoke is a mix of approximately 200 compounds, including particulate matter of various sizes, powerful cancer-causing and mutagenic agents. When it comes to particulate matter, the smaller it is, the deeper in the cells of respiratory tract they get. Not exactly what we want to have in our immediate environment for months at a time. As always, children and unborn babies are at highest risk due to their developing bodies. As for the elderly and those who with chronic respiratory diseases, life becomes a few times more dangerous just by breathing, and the constant irritation of the respiratory tract makes them prone to longer and more debilitating seasonal infections.
Interior Health recommends that wood burning should be done on those days when the venting index is good, which is close to 100. On a regular ‘socked-in’ day, the said index is a mere 10, which is classified as poor. Venting indexes can be found at http://www.env.gov.bc.ca/epd/epdpa/venting/venting.html. It’s an eye-opener for sure, along with air monitors present around town (www.purpleair.com.) Tomorrow is forecasted to have a good venting index, by the way.
I know I am not the only one wondering about this. And I know that when there’s a will, a solution, or many, are found. We ought to find the will to reconsider the way we think about our air, and we ought to change our habits to help keep our air clean. At the same time, we ought to be able to get the industrial polluters to realize that pushing potentially harmful gases and particulate matter into our breathing space is no longer an option. Accountability is not a volatile concept.
Summers will be smokier, we are told. If some of that will be unavoidable, long-term exposure during other seasons can and should be avoided for all the right reasons. The most important one being that nothing matters if breathing is impacted.
It was on Tuesday evening last week that I deleted (again) all the promotional emails from my inbox; there were a few hundred of them. It is now Saturday afternoon and another load of 234 promotional emails are going to meet the same fate. Many of them have to do with the Black Friday sale, which I choose to stay out of for obvious reasons.
For all the times I had doubts about my hammering on the issue of climate change and bringing up various wrongs that suffocate the blue skies and kill the fish, well, the latest news chases away any feelings of inadequacy on the matter. Not that it will sweeten the deal. On the contrary.
I know the conversation about our world suffocating is a few shades darker than many others, plus acknowledging it’s true means committing to live simpler, with less stuff and basically give up some things we collectively file under ‘comfort’ or ‘I deserve it.’ Which we are not quite ready to do. Not yet. Then we go and take another bite of the big pie that promises a feeling of fullness but never delivers. We keep on trying though because we have this short-term memory loss or at least we act like we do.
I think we ought to get some vows happening, you know. How about when a child is born, you must produce a vow that will include (aside from the promise to love the child unconditionally,) a line or two or ten sounding like ‘I promise, to the best of my abilities, to leave as small a carbon, garbage and slavery footprint as I can, when buying things which by the way I know not to buy new save for a few, because I know how much stuff is out there already.’ Then we should renew that vow every year or every couple of years. It might just work. Awareness, you know?
I think we still have a chance. We are the lucky ones though. On this side of the world (and others too,) things get bad occasionally when a storm hits or some monster wildfire, but overall we shake it off and we patch it up by reaching into the emergency fund pockets. There are places around the world though that have so rough already it’s a downer to just read about it, let alone live it. But they do, because they have no choice.
One of the simplest and profound joys of every day is stepping outside in early morning to hike with my dog. I will call it overwhelming gratefulness because that is the best way to describe how perfect a dusty trail that separates meadows of dry, yellow grasses, climbs into a sky so blue it defies the very definition of the colour blue itself. It makes gratefulness for the smallest things even more of a daily concept I should heed before I do anything else.
I sit at the top of the stairs with a plateful of Italian plums after working in the garden. The harvest so far includes four squashes of variable sizes, one gigantic zucchini, a bucket of red and orange tomatoes, and a bowl of shelled beans, red and white. The red ones are plumper, according to lil’ boy, whom I half-buried in a dry pile of bean bushes for the purpose of shelling.
I pulled out bunches of overgrown red and golden dry grasses, disturbing the marigolds and causing a storm of fragrance to clutch to my nose. Their smell is strongly pushing its way into my memory, stomping on everything, leaving but my dad’s slender figure, crouched over weeds and marigolds in our garden. He would work and tell stories, or joke about this or that, or answer many of my many questions about the garden.
I sit at the top of the stairs realizing, plum after plum, that I ache for those times of gardening with my parents. My sister is the only other keeper of these precious times… I sit and remember, plum by plum. It’s no use to get teary but I do. I miss fall gardening with faint smells of leaf smoke from the piles everyone gathered at the end of September.
It’s a progression of sorts, I know that much. Summer to fall to winter and spring again. This is where you get to try again next season. People transition to memories and to more memories. That is the part that leads to the inelegance of my gaze, all teary and bending under the weight of all that cannot be again. It’s the part I process by sitting at the top of our back stairs, looking over the dry hills poking into the blue, and, eating plum after plum, dusty hands and all, I make peace, once again, with the fall, the garden where my parents visit only as memories and my stubbornness to let go.
The afternoon air hugs me warm and fragrant. I walk through short, stubby grass back to the garden. There are still the thick, dark kale bushes to care for and a whole bunch of green tomatoes to ripen. There’s the rosemary and lavender bushes; they will survive the winter. As for marigolds… I’ll plant some again next spring.
