Keeping in mind the air pollution has become a menace in China, the city of Nanjing
has decided to build a vertical forest tower, a futuristic housing concept aimed at checking pollution. The forest tower will absorb 25 tonnes of carbon dioxide a year and give out 60kgs of pure oxygen. The construction of the Nanjing Green Towers will be completed in 2018. The building will have 1,100 trees and 2,500 other plants and shrubs. Two similar towers rising 107 and 199 metres above Nanjing will be constructed. The shorter tower will house a Hyatt Hotel, while the taller one will be home to an architectural school, museum, and offices. Italian architect Stefano Boeri has been given the responsibility to execute the project.
