Public transportation is one of the most feasible solutions for protecting the environment. It reduces the number of private cars hence the decrease of air polluting gases. Considering this, many governments have implemented initiatives that will encourage citizens to use more buses, trams, metros, etc. In my city, Izmir, the metro is the most commonly used transportation. This is because it is faster than other forms of travelling. Although it has some disadvantages compared to the metro, buses are also used very often by individuals living in Izmir.
