For starters there are too many cars on the roads. People find it too easy to jump into their cars - sometimes it's just to pop down to the local supermarket.
If the public transport prices were much cheaper would you use them? I would!
Get into walking
We could get buses that take people into town and back home again, to run more regularly.
People should get more into walking. Parents should club together and drive a group of children to school, which would reduce the amount of cars on the roads.
Another idea I have had is that we should have cycling clubs. This will teach you how to cycle safely and it will also keep you fit.
