This seems like a "Correlation is not causation" weak article. Every few years there is a new likely cause for the increase in childhood asthma. There have been mites, cats, dogs, birds, mold, PM2.5, formaldehyde, fragrances, plasticizers, ventilation and more. There needs to be an all-cause asthma index similar to the (Disability Adjusted Life Years (DALYs) so one can compare the risk factor of a pet bird to a gas stove, or the gigantic PM increase from cooking on an electric stove in a house.

I largely agree with you. PH is terrible at communicating risk, and I hope this is built out.

Causality in public health is built on a lot of things and I think this case has it: Biological plausibility, dose response, consistency. I included this in a draft but took it out in the end. Maybe a framing towards this in the future would be more beneficial
