Earth 2100 is a television program that was presented by the American Broadcasting Company (ABC) network on June 2, 2009, and was aired on the History Channel in January 2010 and was shown through the year. Hosted by ABC journalist Bob Woodruff, the two-hour special explored what "a worst-case" future might look like if humans do not take action on current or impending problems that could threaten civilization. The problems addressed in the program include current climate change, overpopulation, and misuse of energy resources. The events following the life of a fictitious storyteller, "Lucy" (told through the use of motion comics, or limited animation), as she describes how the events affect her life. The program included predictions of a dystopian Earth in the years 2015, 2030, 2050, 2085, and 2100 by scientists, historians, social anthropologists, and economists, including Jared Diamond, Thomas Homer-Dixon, Peter Gleick, James Howard Kunstler, Heidi Cullen, Alex Steffen, and Joseph Tainter. It ended with a quote from writer Alex Steffen, saying "Kids born today will see us navigate past the first greatest test of humanity, which is: Can we actually be smart enough to live on a planet without destroying it?" According to Executive Producer Michael Bicks, "this program was developed to show the worst-case scenario for human civilization. Again, we are not saying that these events will happen — rather, that if we fail to seriously address the complex problems of climate change, resource depletion and overpopulation, they are much more likely to happen."
