A Feature of being Big is that Rhinos eat a great deal, all vegetable. We spend all day and night (with occasional breaks) chewing grass and leaves. We keep busy, not only eating, but processing.
Plants need healthy soil; they can’t just grow without fuel. So, when We Rhinos are done processing, We deposit a lot of Fertilizer. We are done with it, and the plants can employ it. Great and efficient system.
Big Critters with Big Appetites are Herbal Supporters. Everybody wins.
