Man is of a higher order in the scale of life than the plant because he is detached from the soil and can move his body about at will, whereas the plant is attached to the soil and must remain in one position during its entire life. When man eats, he conveys the food to his mouth by the use of his hands and instruments but when the plant eats, it buries its mouth into the Soil and keeps it there as long as it lives. Through a number of roots the plant draws into itself, by the power of Suction such substances as it requires for nourishment from the soil. Man has been nurtured with the essence of plants for millions of years and without them he could not live at all. The substances that make up the structures of plants are the same substances that make up the structure of man.
Plants are the parasites of the Earth and man is a parasite of plants.
Primitive man subsisted upon plant life in its natural state from which he grew a strong and powerful body, to which chronic diseases were unknown. With his teeth he could chew up wood, and without the aid of tooth brushes he retained all of his teeth as long as he lived. But some early experimenter who was more theoretical than practical began to play with fire and introduced the art of cooking foods with excessive heat. This early experimenter did not know that when he exposed food to a higher temperature than that in which it was ripened that the structure of the food would become disorganized and the elements of life would pass out of it. Cooked foods have been the cause of nearly all of the ailments which infect our present civilization.
