Very good article, very interesting facts, and a very good point about bicycles. I couldn't agree more to this piece of article, knowing bikes are eco-friendly machines that can be use EVERYWHERE. I believe if we use more bikes in society the less Carbon will be polluted in the air. Bikes are very popular in other countries, for example in my country Chile the southern part the majority of my family members use bikes to get around such as stores, school and doctors appointments. Whenever I go I can feel the fresh air going in my lungs. In today society many find bikes are embarrassing to use as a transportation, unless you use a car you feel important, but we can change that mind set of people if we all work together and create a movement. Carbon can not win the future!
