Earth 2100_Asking the Question : Is This the Final Century of our Civilization?

Similarities are drawn between a theory for Easter Island's collapse and the realities modern civilization currently faces.

Earth 2100 - A History Channel Documentary aired by ABC.

 A two hour long documentary drama that explores what a worse-case scenario future might look like if the problems we face as a global civilization aren't effectively solved and handled. 
The problems addressed include: climate change, Overpopulation, and Misuse of Energy Resources.

It seems that some viewers had dismissed the film as alarmist.  This wasn't my impression.  The message I got was a hypothetical -yet potential- worse case scenario IF crucial actions aren't taken in time.  Are we/have we taken those steps since 2010?  I don't know as I have not looked further into the status in my detail.
The message came across as more of an eye opener of some very real consequences for a still unwritten future.
