A Green Revolution
 
The CityTree, developed by the German start-up Green City Solutions, is an innovative and multifunctional solution to tackle the growing problem of air pollution in urban areas. These mobile "green walls" are made of plants that absorb fine particulate matter, significantly improving air quality in cities. Standing at around 4 meters tall, each CityTree is covered with a special type of moss that can filter pollutants from the air, making it more effective than traditional street trees.
 
What sets CityTrees apart from regular urban greenery is their modular design. They are mobile, allowing them to be placed in various parts of the city, and their surfaces can act as Wi-Fi hotspots
 
and advertising platforms. QR codes on the structure allow people to learn more about the plants and their environmental benefits.
 
In addition to being a sustainable urban greening solution, the CityTree also gathers data via sensors. This data can be used to monitor air quality and provide real-time information to improve urban planning and environmental efforts.
 
With their ability to filter air and their mobile nature, CityTrees offer an exciting opportunity for large cities facing challenges with air pollution. They are already making a positive impact in places like Hong Kong, where air quality is a pressing issue, and they are poised to help other cities around the world combat the harmful effects of pollution, enhancing.
