Whenever possible I use public transportation system not only because it is cheap but also due to environmental factors. If everybody starts using their own vehicle it will increase air pollution beyond limits accelerating carbon footprint. Moreover by using public mode we are saving fuel which is the need of the hour. Our roads are flooded with vehicles which often cause traffic congestion and if we decide to use public transport it can be controlled to a great extent. Moreover, as we depend more on public transportation this results in the growth of this sector and thereby increases employment opportunities in this field. So there are innumerable benefits in using public transportation system. How often do you use public transportation facility?
