Air Quality in Schools

According to USA Today article:
PS84 on Berry and Grand in Williamsburg rated 38th % meaning 48,790 of 127,809 schools have worse air.
PS132 on Manhattan Ave. rated 33rd %, 41,477 of 127,809 schools have worse air.
The Earth School in the East Village ranked 38th%, 48,611 of 127,809 schools have worse air.
Peshtigo Elementary School that I went to growing up to ranked 59%, 76,270 of 127,809 schools have worse air.
St Mary's Catholic School that I also attended ranked 60%, 76,496 of 127,809 schools have worse air.
Notre Dame Catholic School where Hayden's grandma is the art teacher in Green Bay, Wisconsin ranked 3%, 2,723 of 127,809 schools have worse air.

I wonder if Green Bay, WI has as bad of asthma rates as Brooklyn. I would think they would be much worse by the air quality test. Asthma is heavily promoted in Brooklyn Schools so their rates are probably higher because of the recruitment process that's done. Schools/doctors should teach/practice the Buteyko Breathing Method instead of promoting disease and pushing the use of pharmaceutical drugs for larger profits. If I remember correctly I read an article in the past where the US did a study on asthma patients using this method and 97% of the asthma patients didn't need their medication after holding their breath and breathing slower. The body/blood wants more CO2 and less Oxygen!! :)
