So i started to walk from school to home instead of taking the bus, which is about 3 miles. Later on, i noticed that almost every car that passed by me have these brownish color gas coming out of their car, so when i walk, i inhale it into my lungs(which is terrible to even think about, for me)
So should i start taking the bus again or keep walking?
