Two years ago, Mexico City had the 4th-worst air quality of any city, according to That’s changing, due to new policies — and perhaps helped a bit by vertical gardens!

“Many cities have green reputations,” Damien Cave writes in the New York Times. “Mexico City is a brave new world. The laughingstock has become the leader as the air has gone from legendarily bad to much improved.”

Among the new gardens: 3 giant oxygen-producing sculptures by the non-profit VerdMX. For an energetic Mexican video with some great images, go here!
