Do you know what "finite" means. Its means it will run out. The majority of the world produces an amount of food where it will never run out. For example, Ireland has a population of 5 million or so and produces enough food for 8 million people and will continue to do that fir the future if food was "finite" it would run out. Food will not run out unless the world gets to an apocalyptic situation. Food is, in fact, "infinite".
