land change from history --- The agricultural revolution has added a lot to this. In the book Sapiens Yuval Harari mentions how we made the land a place for grains: "How did wheat convince Homo sapiens to exchange a rather good life for a more miserable existence? What did it offer in return? It did not offer a better diet. Remember, humans are omnivorous apes who thrive on a wide variety of foods. Grains made up only a small fraction of the human diet before the Agricultural Revolution. A diet based on cereals is poor in minerals and vitamins, hard to digest, and really bad for your teeth and gums."
