As we head into another scorching summer, many health professionals anxiously anticipate a surge in heat-related and respiratory illnesses, driven by our warming climate. As temperatures rise, so too does the amount of ground level ozone in our cities and neighbourhoods. The biggest risk this poses for us is the irritation to our airways, making it harder for many people to breathe easily.
It’s not just a problem for children and the elderly – even healthy young people can experience respiratory difficulties from ground level ozone. But the most threatening components of air pollution are those we cannot see. Tiny dirty particles – measuring about 1/30 of a human hair in diameter – can pass into our bloodstream via our lungs, where they risk causing heart attacks and strokes in otherwise healthy people.
While our politicians continue to delay effective action on climate change, people’s health and well-being is being put at risk. Lives are being lost.
