Transportation

1) Use a bike
Riding a bike produces zero emissions.
2) Carpool
By carpooling, we can drastically reduce the amount of emissions we produce overall from our motor vehicles.
3) Take a bus
Same concept as carpooling, by traveling together, we can greatly reduce our car emissions.
4) Take a walk
If you live close enough to school, why not walk to school?

There are many other creative ways to modify our transportation means in order to reduce the smog in our air.
