You can farm without fertilizer, people have done that for a long time. But it is less efficient and if you start having phosphorous problems, fertilizer problems and water problems then, my God, there are 7 billion people in the world and there haven’t always been 7 billion people in the world. We may have gigantic changes again.
Civilization shifts again. Not might, we will. This is something that has been going on since the beginning of time. There will be great investment opportunities; but longer term there are staggering implications.
