text: But that not it! the most advange to this topic is that your helping the envoriment! why you may ask? well like as said in source 3 paragraph 24 " Its a good opportunity to take away lower air pollution" thats some evidence i found because has  Carlos Arturo Plaza was riding his bike thats what he said. So he said bascilly that when you use a car your polluting the environment but when you done use a car then not polluting th environment is a advange. So therefore helping your environment is a advange to this topic, and the most important one!
