Italy has built a vertical forest to help combat rapidly escalating air pollution in the region. The 21,000 individual plats on the side of the building absorb carbon dioxide and generate oxygen, as well as help buffer some of Milan's "noise pollution."
Air pollution in San Jose may not be as bad as Los Angeles and is far better than some international cities like Beijing, but it is significant enough to cause serious health issues. It would be great if we can incorporate creative ideas into our future buildings that can help address the issue while at the same time making the architecture look more interesting. Building parks on top of buildings like Vancouver is another green way to help minimize our pollution.
