Are We Running Out of Phosphorus?

Phosphorus is 100% necessary for all life. Plants, humans cannot survive without phosphorus. Without having an ammonium nitrate phosphate fertilizer, the plant isn't going to grow and it's not going to do any good to humans. The amount that we mine from the earth is between 80 and 85 million tons annually. We're mining almost 30 times the amount that humans excrete.
