I've written about peak phosphorus a bit before at least here, today I'm not gonna write about it myself but gonna recommend this post over at the Collapse of Industrial Civilization blog as he does it much better than me. It's quite a long post but I it's worth it, do watch the videos as well!
Here's a sneak peak:
Phosphorus is a critical resource as there is no living thing without it.
…Just like oil, phosphorus cannot be replaced or artificially manufactured. It can only be recycled through the application of organic matter. However, since urban areas started to use flush toilets, phosphorus was no longer returned to the soil, but washed out into water systems. The use of the local organic matter was then replaced by phosphate rock, which has to be mined or drilled out from the deep soil.
