Ted Talks- Shadow Cities

TED Talks are interesting things. I've probably watched 50 or more in the last year or so.

Today, I watched this one, by Robert Neuwirth, about "Shadow Cities". It's very neat, lots of pictures of squatter villages, lots of information about squatter villages around the world: Rio, Turkey, Kenya, etc. Only about 14-15 min, definitely worth watching.

He has some statistics in there:
* Today 1 in 6 people, on the planet, are squatters (about a billion people worldwide).
* By 2030, 1 in four people. (2 billion squatters of roughly 8 billion people total)
* By 2050, "better than" 1 in 3 people. (3 billion squatters out of almost 9 billion people total)

Those numbers aren't just interesting because of their predictions of squatting/squatters; but for their predictions of the worldwide population.
