Are schools making kids sick?

2. Yes they are

A friend used to pick his grandchildren up from school. He noticed that the school busses idled right in front of the air intakes and front door to the building. He had to find relevant state law and take it to the principal to get that changed.
Where I live, parents must ask to be informed when pesticides are sprayed in the school. Most do not know they have to do this.
Old ventilation systems carry polluted air through the buildings.
Mold is a problem in schools.
Carpets are sometimes a problem.
Strong cleaning products are used.
For all the risks involved, schools cover it up and do not clean up hazardsous situations - they do not want to even hint at liability.
