Of all the everyday plants of the earth, grass is the least pretentious and the most important to mankind. It clothes the earth in an unmistakable way. Directly or indirectly it provides the bulk of man's food, his meat, his bread, every scrap of his cereal diet. Without grass we would all starve, we and all our animals. And what a dismal place this world would be!
Hal Borland, Sundial of the Seasons, 1964
