Did anyone see this last night?

ABC aired a show about the potential for catastrophic civilization disruption due to climate change, over population and resource depletion.

This is the ABC news article about it:

Personally, I thought the beginning of it was pretty good, but I didn't watch the whole thing. I had to be up really early this morning, so I turned it off and went to bed at one point. It was thought provoking and some things I hadn't thought about (like population migration)...but I honestly thought the timeline was too stretched out.

What did you think of it?
