China to Construct Breathing Buildings to Fight Air Pollution

9 February 2017

 - Two ‘vertical forest’ towers, with thousands of trees and other plants growing on their sides and roofs, will be built in the Chinese city of Nanjing. The buildings will help to clean the air in the city of over 8 million.

A vertical-forest building is covered in terraces that contain hundreds, or even thousands, of plants, forming a compact forest in the middle of urban areas, that help to clean dirty city air. Some 3,600 plants will cover the two buildings, the brainchild of Italian architect Stefano Boeri.

The two towers will eat enough carbon dioxide to make 60 kilograms (132 pounds) of oxygen every day. The average person consumes about 140 liters (about.2 kilograms) of oxygen a day. Thus, the two buildings will offset the pollution created by an estimated 300 people.
