"Dangerous indoor pollution could be tackled with air purifiers but costs are too high for many, researchers say"

"Toxic pollution from wildfires has infiltrated the homes of more than a billion people a year over the last two decades, according to new research.

The climate crisis is driving up the risk of wildfires by increasing heatwaves and droughts, making the issue of wildfire smoke a “pressing global issue”, scientists said.

The tiny particles produced by wildfires can travel thousands of miles and are known to be more toxic than urban air pollution, due to higher concentrations of chemicals that cause inflammation. Wildfire pollution has been linked to early deaths, worsened heart and breathing diseases and premature births."
