I think it's an interesting and fascinating article, but I was misled by the "tool tip text" that showed up when my cursor hovered over the link to this page (taken from the subtitle of the article).

The similarities offer a look at just how ever-growing societies could collapse.

Where did the author get that idea? Ant culture has evolved along with their physical characteristics to handle the problems of proliferation and massive population density. They seem to be doing just fine. The article ends with a suggestion that ants "are arguably among the most successful organisms on the planet."

She seems to have an agenda that wasn't supported by the facts... it hasn't happened with the ants, but is rather drawn from a hypothesis from David Queller and Joan Strassmann at Washington University.
