According to the book The Forest, “as many as 1,350 creatures... may be found in an area a foot [30 cm] square and an inch [2.5 cm] deep, and that does not include the billions of microscopic organisms in every handful of earth. ”
Raamatu „The Forest ” järgi„ võib 30 ruutsentimeetri suuruselt alalt kuni 2,5 sentimeetri sügavuselt leida koguni 1350 elusolendit, arvestamata veel miljardeid mikroorganisme igas peotäies mullas ”.
