A study by the Polytechnic University found that students who travel to school by school bus has worse lungs than those who walk to school.
Carbon dioxide on school buses exceeds the guidelines set by the government, possibly due to the number of children packed into the bus. Dangerous pollutants found on some of the buses more than double the guidelines set by the World Health Organization. To top it all off, ventilation and buses running on diesel fuel worsens the problem.
So get your kids to skip the bus and walk to school—more exercise is always good anyway.
