Biking is the best form of transport. It keeps up your fitness and helps the planet because it reduces the need to build disposable cars. In my opinion, it would be good for people to use public transport, so less cars are on the road.

I do travel in a car, so the emission from diesel engines contributes to production of ground level ozone damaging crops and other vegetation. 

I don’t think long distance travelling should be restricted. Some people like me, live in the country maybe even an hour away from town, so how would they get their supplies?
