We are running out now. The price has been rising for many years. We have no way of conserving it. We are using more each year. You are confident in what technology? Are you thinking that we may as well just let the disparity between supply and demand continue to increase because humanity will sort out the crisis when it gets bad enough to force a solution? How can you be sure that panic will provide the answer? That is like going back to sleep in a burning building with the confidence that the fire brigade will arrive on time.
If we forget about phosphate for a moment, the problem is simply that the sustainable carrying capacity of the planet is finite and the population is now 3 times that.
Now is the time to act against overpopulation before a crisis arrives.
Many of humanities other problems are related to overpopulation. For unemployment and all that goes with it, read overpopulation. As we become increasingly more efficient in manufacturing, how can we be nonchalant about increasing population?
First let me correct you, We are not running out now it will be what 200 years before depletion happens such as Oil will run out way before then. There are obviously ways to conserve the usage of phosphorous and there are technologies in place for such eventualities for almost every resource on this planet even if it is the case where there is massive runoff into the ocean in sewage which is the ultimate fate of much of this phosphorous we could always extract it from the ocean as needed, my point being there is always methods if they become economical to recycle phosphorous. Supply and Demand will sort out the issue as resources are determined as more expense which will lead to the conservation of the material for important uses which the most net profit can be produced as scarcity happens it has a natural way of balancing itself out. There is the issue of overpopulation but I am certain that this planet can support many more than 2.4 billion people as GAHD said this seems to be a number pulled out of a hat, while overpopulation is an issue it is not something that cannot be addressed with population control if the time arises were we actually cannot support a certain population people that cannot survive will not survive. The idea which I presented earlier in this thread will happen regardless because people with less means to survive will suffer the fate of starvation which is why any effort to prevent this lack of phosphorous situation is good, though not as critical as when the Earth runs out of fossil fuels if there is not something like Hydrogen Fusion or Bio-fuels to replace it.
