Greater Mexico City is the third largest metropolitan area in the world and the largest in the Western Hemisphere with a population of over 22 million people. The city is home to much of Mexico’s economy, industry and culture.
However, it is also horribly polluted, contributing 1.5 percent of the world’s greenhouse gas emissions. The city is so polluted, in fact, that 4,000 people die every year as a direct result of the toxic chemicals that float in the air over much of the city. The Mexico City Human Rights Commission declared that the state of the city was a “violation of the right to a healthy environment.”
The good news is that the city’s leadership appears to be finally making a push to clean up their act. A new project has been launched called Sustainable Housing Units, which seeks to create a vegetative urban environment to help clean up the city's air.
The project will place vertical gardens, rain water filters and solar panels in newly constructed housing towers. The first of these will be in the La Valenciana area of the Iztapalapa zone. The city has installed 10 solar-powered water systems here, and has also transformed 700 square meters of wall space (approximately 60 x 105 ft) into a rich vertical garden with rocky soils for water filtration.
Marco Antonio Hernández, who worked with the company that installed the new green building additions, has confirmed that the government is funding 30 similar projects in other zones of the city. When it comes to Mexico City, the air quality can hardly get worse, but it appears that the city is at least beginning to make a sincere effort to make it better.
