I remember many years ago, when the newspapers published that Mexican women traveled to the country to give birth to their babies, because of the terrible pollution in the City.
At least, some effort is shown to find a solution. From New York Times, by Damien Cave:
“We must cultivate our garden,” Voltaire famously wrote at the end of “Candide,” but even he could not have imagined this: a towering arch of 50,000 plants rising over a traffic-clogged avenue in a metropolis once called “Mexsicko City” because of its pollution.
The vertical garden aims to scrub away both the filth and the image. One of three eco-sculptures installed across the city by a nonprofit called VerdMX, the arch is both art and oxygenator. It catches the eye. And it also helps clean the air.
“The main priority for vertical gardens is to transform the city,” said Fernando Ortiz Monasterio, 30, the architect who designed the sculptures. “It’s a way to intervene in the environment.”(.....)
“Both L.A. and Mexico City have improved but in Mexico City, the change has been a lot more,” said Luisa Molina, a research scientist with the Massachusetts Institute of Technology, who has done extensive pollution comparisons. Mexico “is very advanced not just in terms of Latin America, but around the world. When I go to China, they all want to hear the story of Mexico.”
Partly, it is policy. Starting in the 1980s, Mexico’s government created mandates that reformulated gasoline, closed or moved toxic factories, and banned most drivers from using their cars one day a week. More recently, Mexico City added a popular free bicycle loan program and expanded public transportation systems.
