Ancient termite megapolis as large as Britain found in Brazil, by Bard Wilkinson.

Researchers have discovered a gigantic complex of 200 million termite mounds in northeastern Brazil, which may be up to 4,000 years old and covers an area about the size of Great Britain.

Although visible on Google Earth, the conical mounds, some of which rise up to 10 feet high, are largely hidden from view at ground level in semiarid, thorny-scrub forests, according to research published this month in Current Biology. …

The amount of soil excavated is … equivalent to 4,000 Great Pyramids of Giza …

The mounds, more of which are still being built, came to scientists’ attention when some of the lands were cleared for pasture in recent decades. …

The mounds are not nests but rather the result of the insects’ slow and steady excavation of a network of interconnected underground tunnels, which resulted in waste building up in cones on the surface.

I’ll bet this Britain-sized city doesn’t practice immigration or diversity.
