Massive Air Purifier
A massive air purifier shaped installation will be built in public places in New York City, such as 14st Union Square. There will be a door on the wall of the installation, and audiences can get into it. Inside of the air purifier, a tree is planted and a information board will be placed with the tree- the information board says that trees clean the air and produce as much oxygen in a season as 10 people inhale in a year- basically a tree performs as 10 air purifiers. The installation intends to provoke public curiosity and buzz and encourage the audiences to plant trees with Million Tree NYC.
