Climate change as a matter of fact: Mexico City

As noted in the video:

1. The population of Mexico City is 21,000,000
2. 70% of water consumed here is from subterranean aquifers.
3. 23% of water is pumped from outside the city.

Mexico City, Parched and Sinking, Faces a Water Crisis.  (The New York Times, 2/17/2017)

It is a cycle made worse by climate change. More heat and drought mean more evaporation and yet more demand for water, adding pressure to tap distant reservoirs at staggering costs or further drain underground aquifers and hasten the city’s collapse.

Much is being written about climate change and the impact of rising seas on waterfront populations. But coasts are not the only places affected. Mexico City — high in the mountains, in the center of the country — is a glaring example. The world has a lot invested in crowded capitals like this one, with vast numbers of people, huge economies and the stability of a hemisphere at risk.
