In the video, researchers pump 10 tons of concrete down an ant hole and then slowly, carefully excavate the site to see what an ant colony looks like. The result is an intricate structure, equivalent in labor to humans building the Great Wall of China.
And then you think, "Oh, and we just pumped 10 tons of concrete down it. Oh. We're … kind of assholes sometimes, aren't we?" Sorry ants. Sants.
