I hate to point this out, but obviously no one thinks about this.
Prior to the 1980s...insulation of homes was marginal or 2-star at best. But the environmentalists came and said that it’d be really helpful to turbo-charge our home insulation and get the better windows/doors. So when we heated or cooled....it stayed in.
Well...not only did the heat stay in...but the radon stayed in as well. Unless you have some exhaust fan rigged up and regularly air out the heavily insulated home...it’ll continue to build up. We can go to any area where radon was somewhat common before fracking came along, and then look for areas without any fracking (there are plenty of these areas)....and find heavier concentrations of radon.
This is NOT rocket science. If you do something....there’s a consequence, and it’s not all a good thing.
You’ve probably just nailed it.
Back in the 80s the libs decided to save the forests by eliminating the use of paper shopping bags. Many of us argued at the time that bags can be made of recycled material, but replacing them with plastic would be disaster for land fills. Now they have their panties in a wad because of the non biodegradable plastic that has clogged the composting process in landfills. But the good news is they've moved past it all to personalized shopping bags - some even made with hemp.
