Hosted by Lauren Spates, episode 2 looks at the impact of more-fierce fire and flood on our immune system, our lungs and our brain. We talk to scientists, doctors and other experts who say it’s misleading to think that you’re safe from the effects of wildfire smoke if you live far away, because smoke knows no boundaries. It’s also misleading to think that once the smoke is gone, you’re safe, because invisible toxic particles are left behind. We ask what exactly happens when we — and our children — inhale wildfire smoke and carbon dioxide, and what can we do to protect ourselves?
