Haven't seen anything about this yet, but it's a series done by the same people who did the Planet Earth series which follows how humans have adapted to certain environments around the world. It comes with the great shots and huge production value you can expect, and while I don't have the download links, 7/8 episodes have aired so they should be easy enough to find floating around on the internet.
I like it a lot. There some crazy ass scenes you just didn't get in planet earth/life. The treehouse people were awesome. And the guys that just walked up to wild lion while they were feeding...holy shit. The last episode is out on torrent (whole season is). It covers urban areas. I haven't watched it yet though.
They also cover a sky burial (google it). They don't show the particulars though.
