That's quite debatable. What is clear, though, is that the city's current airport is bursting at the seams.

It's a good idea for Mexico City to substantially increase green space. However, it's also a good idea for the city to augment its air transport infrastructure. The AMLO government has made a bold decision, and time will tell how it works out.

I think it is a good idea considering the temporal frame of reference. Payback on projects like these take decades. Furthermore the objectives of whichever local official with any sense of wit and honor most certainly must encompass and protect the needs of local citizens and global directives at the expense of energetically and ecologically expensive tech of arguably dubious merit.
