These days, literally everyone is talking about cities and building them.

I hear of “smart cities”, “sustainable cities”, “clean cities”, “cities for all”!

My mind, however hasn’t fully thought about one self-sustainable city in the world.

Do you know of any of these places that have everything moving smoothly by themselves, without any interruption?

What does the term “self-sustainable” mean, anyway?

And, are you living in a city or near one?
