Air-pollution has been a critical issue for lots of metropolitan. Recently, Beijing was just swamped with smog and observed increasing cases of respiratory related diseases. Authorities are finding different solutions to curb the level of pollution.
Milan, the fashion center of the world, is one of the most polluted cities in Europe. In 2003, a medical study pointed out that breathing air in Milan is similar to smoking a pack of cigarettes each day.
Milan has limited space for greenery. The city turned to architect Stefano Boeri to create the world’s first vertical forests, incorporated into the “Bosco Verticale” apartment towers, currently under construction and nearing completion.
The design would serve multiple functions. In addition to producing oxygen, mitigating smog, and providing an ecosystem for insects and birds, the trees and plants on the terraces will help to cool the apartments and reduce the energy costs for air-conditioning, especially when summers in Milan can get hotter than 38 degrees Celsius.
