Explain Like I'm Five
Some people in a place called Los Angeles have really big walls made of bushes to keep their homes private. But in a different place called Austin, some smart people made a new way to have privacy and make the environment better too! They made vertical gardens called VertiFlow, which are like big cylinders made of old cans that hold water for plants to grow on. These gardens are not expensive like the big walls in LA and they also help clean the air and make less noise. People in Austin can even help make their own gardens and learn about taking care of the environment. The people who made these gardens want everyone to work together to make the world a better place!
