The BBC has a series called Human Planet, which documents the many interactions between humans and nature. It's a look at how people around the world live on the edge of nature, which can sometimes be beautiful and sometimes be tragic. In the same vein as Planet Earth from last year, I'm hoping that it will eventually make its way over the pond via the Discovery Channel, but in the meantime, here's a few pictures and a link to an audio slideshow from photographer Timothy Allen. Definitely worth a look.
