Wow I never realized how much a bicycle could impact someone's life, this women in Zambias whole life changed after she started using the bicycle she now has 2x the income, what a beautiful thing! Bicycle can be use for more than just exercise even though that is one of its great contributions but it can be a way someone can get to work and that what's so great about the bicycle. It has so many functions and can make our lives better. Our society is so focused on doing things as fast as we can, never stopping which is a reason we use our cars but our cars are causing so much pollution, it's interesting to see we can cut down on co2 emission by 11% just by riding our bicycle. Bicycles deserve at least one day to be celebrated which is why I support the article for the UN to recognize and have a national bicycle day!
