This is the place for discussing the potential collapse of modern civilization and the environment.

Collapse, in this context, refers to the significant loss of an established level or complexity towards a much simpler state. It can occur differently within many areas, orderly or chaotically, and be willing or unwilling. It does not necessarily imply human extinction or a singular, global event. Although, the longer the duration, the more it resembles a ‘decline’ instead of collapse.

Another reason to suspect we are going to face "sudden" "unanticipated" harvest declines and subsequent famines in short to mid-term future.

There is still plenty of potassium its just about cost of extraction and shipping.

The phosphorus supply is much more concentrated mostly in morrocco & western sahara , we high graded the low contaminant stuff already and are getting nastier P with more heavy metals. Africa is almost wholly P deficient and population is supposed to rise by 3+billion, yet they have the highest fertilizer costs in the world because supply chains and transport dont penetrate cost effectively with roadblocks every 100km across much of the continent that require bribes. so paradoxically the continent with like 80% of global P reserves and the most desperate need gets the least. Even governments and corporations doing land grabs have had trouble getting production up to standard and the costs of inputs in africa .
