As the world is moving towards economic scarcity and limited resources for the coming generation, I feel that converting from individual cars to mass transit systems is very beneficial, not only in terms of pollution but it will helps reduce the traffic congestion as well.
Apart from that, cars can consume a lot of fuel which ultimately leaves an individual with a less disposal income, hence using a mass transit system can be really be beneficial if an individual is trying to save his/her money on travelling charges.
