Sterile Earth Era

The Sterile Earth Era is an era of the future.

Causes
What caused Sterile Earth remains a mystery. It might have been caused by Philip Burton, who said he wants to collect Green Energy from the anomalies. In order to do that, he would have to manipulate the anomalies. So, the theory goes that Philip starts manipulating the anomalies, and it causes atmospheric changes that result in a barren lifeless planet. Another cause could be that Connor Temple, in an attempt to stop it, actually causes it.
