Biking and walking are not only good for you physically, but they are good for the environment too! Unlike cars, buses, or planes, biking and walking are zero emission activities!  You won’t be polluting the air if you decide to walk or bike around a city. In fact, there are people who only use zero emission forms of transportation while they are traveling, even while going from country to country. Now that’s what I call responsible tourism!
