Those pesky ants - so smart they build underground cities

Ants – the bane of every islanders life. But did you know that collectively they can build subterranean cities so immense that each one would amount to the equivalent of man building the Great Wall of China. A group of excavators poured cement into a disused ant colony and dug away the ground so we could see the intricate paths and enclosures that they create as a group. They might still annoy us in those summer months but watch this video clip from myamazingearth.com and they might earn a little more respect than you might give them now.
