The Giver- How they solved "our worlds" problems

One problem we have today in our world is car pollution. There are so many cars that now there's pollution everywhere. In The Giver they have solved out car problem by giving everyone bicycles instead. In The Giver you don't you don't get you bicycle untill your an "8" so before that you must ride with you mother or father. I think this is a very good improvment because our world would not be polluted this way and we can also save more gasoline and money.
