We're in Canada at the International Association of Wildland Fire Conference this week, and will be pulling some folks aside for some quick conversations about the conference themes and the research being presented and discussed. Our first "rapid fire" episode guest is Sarah Henderson, who works for the BC Centre for Disease Control as the scientific director of Environmental Health Services. Sarah has some fascinating insights into our perceptions of wildfire smoke, some common paradoxes that come up in the ways we talk and think about smoke, as well as some legitimate, scalable solutions for reducing the impacts of wildfire smoke, especially on susceptible populations like those experiencing homelessness, those who don't have the financial means of improving indoor air quality and those with preexisting health conditions that make them particularly vulnerable to smoke's impacts. Thanks to Sarah for taking a moment to chat with us, and hopefully this conversation provides some useful context for those who felt the effects of smoke this summer and fall.
