Have you ever wondered exactly how many ants live on Earth? The research published today provides an approximate answer. We conservatively estimate our planet harbours about 20 quadrillion ants. That's 20 thousand million millions, or in numerical form, 20,000,000,000,000,000 (20 with 15 zeroes). We further estimate the world's ants collectively constitute about 12 million tonnes of dry carbon.
