Many people have strong views about allowing ONLY public transport in cities. There are arguments both for and against it.
On the one hand, using only public transport in cities is good for the city, because there would be less pollution and the environment would improve. Another advantage is the traffic; if we only use public transport in cities, traffic will reduce and it will be easier move in the city.
On the other hand, allowing ONLY public transport in cities has disadvantages too: local residents would have less comfort for moving in their city, because we would not use our private vehicles. It would take longer to get to different places
To sum up, I believe that we have to look after our environment; using only public transport in cities would be a good idea to do so. I think that we should not think only about ourselves and we should improve our planet.
