Air quality is massively impacted by wildfires.
For a start, whatever is burned will produce fine particles in the atmosphere that can then enter the human body causing short term and long term health impacts.
It's usually vegetation that burns - trees, bushes, wood etc - and when these are burned pollutants like carbon monoxide, carbon dioxide and nitrogen oxides are released.
High pressure can often create a temperature inversion.
This is where a layer of warmer air acts as a lid on a top of cooler air, trapping pollutants near the surface of the Earth, where of course, we breathe the air.
Wind patterns could then disperse the pollutants across a much wider area than the actual fire itself.
There aren't only impacts on public health but also on agriculture, crops are damaged and lakes and rivers can turn more acidic damaging their ecosystems.
