Please, correct my linking expressions The Problems of 21st-century Urban Living In cities everywhere, there is growing concern about the effect of motor vehicles on the inhabitants' quality of life. Some people want to prohibit cars from urban areas, and to a great extent I agree. Firstly (1) these vehicles poison the air with their exhaust fumes, contributing to the clouds of smog that hang over many cities, especially in sunny weather. Then / Secondly / Besides (2) , the sounds of engines and car horns destroys the peace of our neighbourhoods, even at night. In addition / Thirdly / Also / As well as that (3) , the huge amount of traffic nowadays makes cities less pleasant places to live. For instance, crossing busy roads often takes ages. Moreover / Besides (4) they can be dangerous, especially for children, and for old or disabled people, (5) as well. In my opinion / I sure / I think / I believe that (6) , there are often alternatives to travelling by car, such as the tube, buses or trams. Also (7) , if there were no cars, far more people would cycle to work, or they could walk there in the fresh air. So (8) , urban areas without cars would be much better places to live. As long as other means of transport are available, therefore, I believe our cities should become totally car-free.
