How have the car and aeroplane affected our way of life?

I think the car and aeroplane has made our life much easier. Firstly, we can save our time and we don't have to spend years for travelling abroad or going somewhere in our city. Secondly, these vehicles can be used by disabled people and it is a great advantage. But the number of cars and aeroplanes has increased rapidly since last years, so it is a serious problem, because of the air pollution. And that is very harmful and dangerous for people and our planet.
