Ant expert E.O. Wilson, a professor at Harvard University, once estimated the total biomass of ants on Earth is equal to that of humans.
"Ants are changing the environment," said lead study author Ronald Dorn, a geologist at Arizona State University in Tempe.
Dorn has discovered that certain ant species "weather" minerals in order to secrete calcium carbonate ? better known as limestone. When ants make limestone, the process traps and removes a tiny bit of carbon dioxide gas from the atmosphere.
