On top of the concerning environmental conditions, more people are spending more time outdoors due to the ongoing COVID-19 pandemic. Given that most wildfires are caused by human activity, the summer of 2021 has the potential to be worse than any season before it. Exposure to wildfire smoke is associated with a range of acute effects, particularly for those with respiratory diseases. Evidence of longer-term health effects is also starting to emerge. Outdoor air pollution from vehicles and industry can be reduced though new laws and technologies, but that’s not true for wildfire smoke. In addition, we can’t stop breathing when it’s smoky and it’s not practical to relocate to less smoky locations.
