Environmental pollution is now becoming more and more serious, I discussed with the students a good bike or bus, and some students to schools far away from home, it is necessary to take the bus, but not too far away from the schools the majority of students choice of walking or riding a bicycle.
I think the bike is better, because they can exercise, but also more environmentally friendly and will not pollute the environment, cycling is a sport, albeit tired.
Therefore, I advocate for everyone or let their bike. Enhance the physical, why!
