Do you think mold is somthing we need to worry about in school

Personally, I think it is. Not only that mold is very unattractive and would not represent your school well, it can cause issues with your respiratory system. It can cause a lot of problems with children that have asthma and allergies or maybe they are sensitive to it. Even for the children who do not have those two, it can cause Illness and infections.
