Take just the top inch of soil, the world squirming right under my palms. In the top inch of forest soil, biologists found “an average of 1,356 living creatures present in each square foot, including 865 mites, 265 spring tails, 22 millipedes, 19 adult beetles and various numbers of 12 other forms…. Had an estimate also been made of the microscopic population, it might have ranged up to two billion bacteria and many millions of fungi, protozoa and algae—in a mere teaspoonful of soil.”
