Have we passed peak diamonds? Just as a prior blog outlined the concept of peak oil, gas, metals etc, the recent news not suggests that diamond miners are decreasing their exploration investments because the number of new finds is decreasing each year, and those found are far more expensive to extract than the current values. Sounds like oil? We find less each year, it is more expensive and current oilfield yields are on the decrease. Phosphorous is similarly situated which is why there is much research taking place to find means to recover phosphorous from ag lands and wastewater effluent – recover phosphorous meant to be resold to ag interests as fertilizer as the price of phosphorous continues to increase as a result so increasing demand and decreasing supplies.
We are also being told that while peak diamonds have passed perhaps chocolate will become scarcer and the demand for chocolate is outstripping the supply, and the available land for cropping is being out competed by more lucrative crops in South America. At some point the available land for many crops will be exhausted. It is then that we reach peak agriculture?
