empty board?

I don't get why this board has only 1 post. I just saw this documentary and loved it. I've seen quite a few docs and this one was great because it wasn't about bashing the plastic industry (it's easier to criticize) but it was about what we can do to change things. The different stories, ideas and industries were very inspiring. I'm not an incurable optimist and I don't have a lot of faith in humans but from a scientific point of view, i found it intriguing.
