It’s well known that vehicular traffic is deadly no matter where it is and how much of it exists. Even with all the evidence cities in North America put cars first with the occasional protections like bike lanes and pedestrian crossings. What we also need to talk about is the threat cars bring to our lungs.
The Canadian Association of Physicians for the Environment have released a report outlining how many health gains come from eliminating cars from our streets. Electric cars aren’t the solution because they are still only focused on single occupants and give off particulate matter when braking.
Recommendations for achieving those benefits include stronger fuel content and vehicle-type rules, restrictions on idling and the use of vegetation barriers along busy roads. Cities can also implement low-emission zones that favour electric vehicles, bicycles and public transit. Ventilation systems in buildings, which became a focus during the pandemic, can play an important role in preventing traffic-related pollutants from infiltrating indoor spaces.
But like many pollution issues of the past century, effective solutions typically require governments to motivate change.
“Problems like this just cannot be tackled at the individual level,” Dr. Green said. “If an individual is concerned about this issue, then they need to demand that their politicians take action.”
