Mexico City is elevating urban ecology to new heights with an initiative called "via verde" or green way. The project aims to transform hundreds of pillars supporting flyovers and elevated roads into vertical gardens to reduce pollution while improving the cityscape, says director Fernando Ortiz Monasterio.
"We live in a very grey city. Very grey and we forget because we have become used to that being our urban landscape. As soon as we find a park, a green landscape, we realize our mood changes." The gardens are actually walls made out of metal frames and cloth that are placed on . . .
