Boojho wishes to contribute in reducing air pollution. Which vehicle should he use for going to school?

Boojho should use a school bus if he wants to help reduce air pollution.

By using the school bus, the number of vehicles being used will reduce. Instead of 20 cars or 20 scooters one bus would carry 20 children.

20 cars or scooters would have caused a lot of pollution which got reduced because of one school bus being used.
