In an attempt to curb the production of toxic gasses, China is building a city centred around 40 000 trees.
The new Liuzhou Forest City is planned to host 30,000 people and will be home to roughly a million plants from over 100 species, as well as 40,000 trees being planted in facades over almost every surface imaginable.
The trees and plants will absorb almost 10,000 tons of CO2, 57 tons of pollutants per year and produce approximately 900 tons of oxygen annually. They will also decrease the average air temperature, create noise barriers and improve the biodiversity of living species, generating the habitat for birds, insects and small animals that inhabit the Liuzhou territory.
The new Liuzhou Forest City will connect to the existing Liuzhou via a series of fast rail services and electric cars; it will also reportedly house a number of schools and two hospitals. The city aims to be self-sustainable with regards to power, thanks to geothermal and solar energy resources.
