So we're at a new resource shortage. Global peak phosphorus happened in 1989. Phosphorus can be recovered though, so it isn't too critical, but it is definitely bad for growing grain. We consistently as a planet consume more grain every year than we produce. Eventually those fat stockpiles are gonna hit bottom, and then shit hits the fan. We have already seen tortilla riots in Mexico, and commodities shortages and export controls in nearly half the world.You can find a debunking of “peak phosphorus” here. (By the way, considering that the stockpiles we're drawing down were probably the result of farm price supports, the alleged food shortage might simply be the result of moving away from a silly policy.)
The really odd thing is that the current alleged phosphorus crisis was apparently passed around from loon to loon for years without coming in contact with reality. A few years ago, I even saw a claim that Coca Cola will use up the world's supply of phosphorus in 40 years:
one exampel, just Coca Cola will whit in 40 years used all fosfor on the earthI knew the left side of Nuts R Us hated Coca Cola, but this is ridiculous.
