Ant mass

 Ants - annoying, insignificant, tiny creatures. Annoying, yes. Insignificant, no. They don't look like much in your yard, but they're important in the big scheme of things.

"Lowly ants possess the greatest total mass of all land-dwelling animals . . . 15–25 percent of the total mass of living land animal tissue." Surprising, unexpected. 

Scientist Hugh Ross thinks that the super high number of ants has helped preserve earth's suitability for human life. Their activity takes greenhouse gases out of the atmosphere. The soil is more beneficial for plants when ant hills are near, and ants remove 50+% of the detritus on the forest floor of tropical rain forests.
