I try to use public transportation whenever I can. I take the bus to college and walk home. When my mum wants to give me a lift, I always refuse, as I can get there quickly by bus. Also the buses in my town are electric so they are environmentally friendly!

They don't produce any pollution and help you to keep fit at the same time.
