Greening of Austin: City Walls Become Gardens for Environment

In the future, the city of Austin in Texas became very green! They passed a new law that said all the walls in the city had to have gardens on them. This made the city very pretty and helped the environment too! The gardens made the air cleaner and brought lots of animals to the city. People were very happy about it and started growing their own gardens too. Other cities saw how great it was and started making their own gardens too.
