I can think of a few hypothesis, but I’d hit all the reasons we already know that people in their 30s are getting cancer first, like: Natural gas burning inside with poor ventilation (solve by pushing electric everything, paid for by carbon tax paid by big oil) ICE car exhaust (solve with EVs, subsidised by carbon tax paid by big oil) Second hand smoke (ban smoking in public and within XX distance of a child, and make support for parents to quit free from cigarette taxes) Microplastics in the water and the air including tyre dust (start regulating this/coming up with a long term plan to reduce it and filter it out, and put a government subsidy on certified and professionally installed under sink microplastic water filter products… paid for by those who put the plastic there in the first place) Poor indoor air quality/high VOX (mandate air flow minimum levels for all new builds and make extraction fans for offices a normal requirement, and give tenants something to lobby against their body corporate to improve airflow in uselessly designed buildings since “sick building syndrome” is real but often impossible to know before you sign the papers)
