Well next to the bus you can also use a tram as public transport,which is more ecological. It makes the city cleaner. And a lot of people actually uses the trams so they help reduce CO2. They also walk a lot because it is faster sometimes to go on foot then to use a bus or a tram. In the heart of Krakow you can use a traditional cab(carriage).
The second day there we were learning about ecology around the world. We were introduced different ways of producing energy and a lot of them were ecology friendly to the environment.
Later that day we were talking about how can we help reduce CO2 and then we watch a short interview about ecological footprint and learned that people still don't known much about ecological footprint.
