Phosphorus: The finite supply of it is why Jeremy Grantham predicts a grim future for much of the world's population. As production of the critical ingredient for fertilizer drops, so will crop yields, which will threaten the ability to feed the world's population. Grantham thinks the finite supply of fertilizer and limits of crop yields already are starting to affect food prices.

    Agriculture yields continue to increase in developed countries - think about the potential in developing and 3rd world countries!


    The biggest threat to human health is fresh water availability.

    Malthus 2012. Higher food prices have more to do with farm tariffs, droughts, and US ethanol policy than a lack of fertilizers. As farmers in the third world get more productive, prices will ease. Its Econ 101:High prices cure high prices.

    I agree - so what if we start to get short on phosphorus; will we, have enough water - will drought ridden farmers even need the phosphorus when they have no water; let's focus on climate change and weather patters for the overall good of humanity.

    Just stop feeding the plants that need phosphorus to animals.


    Problem solved, temporarily.


    Until we run out of water. That should come from the oceans, which are rising. Yes, because of global warming.


    We humans WILL find some way to eradicate ourselves, probably through over-population.


    Just give us time.
