Living in a busy city has made some of us almost unable to distinguish the fact that there is pollution in the air. We have grown immune to the stale air that we breath. However the World Health Organization has revealed statistics that one in eight deaths in 2012 was caused due to air pollution.

Architects around the world are working with scientists coming up with ways to make buildings that can actually help lower the air pollution experienced by people inside the buildings. The Manuel Gea Gonzalez Hospital has a smog eating facade that is covered with titanium dioxide which works as a catalyst to break down pollutants into less harmful components.

This allows the air within this hospital in Mexico City to be less polluted than that outside. Inspired by this development London is also set to use titanium dioxide in similar roles. There is a Palazzo in Milan, Italy which is also likely to have a air cleansing exterior.

Although scientists are skeptical about these measures reducing global air pollution, there is a big trend of using innovative technologies to deal with the issue. The ongoing science projects in the field are doubtless going to help reduce air pollution in the future.
