It is not necessary to always use public transport, sometimes you can walk or cycle, it is cheap and healthy. If it is absolutely necessary to use public transport, use the bus, the metro or the train because with a single transport a lot of people can go compared to the car, because not so many people can go and it is also cheaper.
Almost 30% of the total CO2 emission in the EU (European Union) are caused by our mobility, when driving a car, taking the train or flying. Emissions produced by transport are not only irreversible in warming the planet, but also one of the main causes of air pollution. As a result, it affects our health. Sustainable transport can save you money, improve your health and reduce your enviromental footprint as well.
