This new normal of near-constant wildfire smoke annoys me as much as the next person. But it serves as a reminder that we share one fragile atmosphere that we're collectively screwing up. Fruitless to waste all this energy pointing fingers like children when we should be joining hands to fix this. It's like nature's warning signal.
Whether it be wildfire smoke, a global pandemic, or heat waves, nature know no geopolitical borders. So maybe instead of squabbling over whose smoke is whose, we could acknowledge that we're all in this smoldering mess together. We only have one planet to live on, and we only have one atmosphere to breathe from.
(just food for thought)
