The phosphorus crisis: A growing concern for sustainable food | Daniel Magnone | TEDxBrayfordPool

[@rpbajb]

Isaac Asimov wrote about phosphorous' absolute limit to growth back in the 50's or 60's.

[@Alexander_Kale]

And he did so without constantly pointing out his profession or how he wants to save the world. But then again, Mr. Asimov was a wiser man than most...

Thank you so much for talking about your studies and research. Excellent argument on food security.

I have farmed organically for 40 years. I have never applied phosphorus. Soil test proves an abundance of phosphorus. Maybe you need to look into this.

[@yousafabbas6914]

@@tidtidy4159 how to make it available?

[@vecstrandedonabarrenplanet7343]

Mankind will have to reinvent all waste recycling systems, both solid and liquid, to create human based fertilizers, and return those nutrients to the farm's soil. Same goes for cattle manure and urine, with fertilizers based off of them as well. Don't forget about the food waste we produce either. The effiency of farming without our industrial fertilizers is that of the 1800's, meaning I don't expect a sustainable carrying capacity beyond 100 million Humans at MAX.

Basically, phosphorous, nitrogen and potassium are the nutrients needed in our ecosystem nowadays. And sadly, this nutrients became unavailable to us, thus came the topic on crisis about this basic nutrients needed by living organisms. I believe that it is also important to consider possible solutions in this problem particularly Nitrogen, potassium and phosphorous. How can we resolve this problem?

[@ryanbeard1119]

Organic matter insteady of inorganic concintrations of these elements

[@RealEstateInsider247]

Lack of nitrogen, potassium and phosphorous is not a problem at all. Misunderstanding of the problem (like this Ted Talk) is the problem. I explain a bit in another comment.

[@Ms123kill]

perhaps not nitrogen or potassium but phosphorus for sure

[@QANGOR]

When more or less is the FINITE PHOSPHORUS supposed to be depleted?

100 years ignoring Morocco's supplies, 300 including. Morocco is a superpower in waiting...

[@ryanhill1303]

thanks dan loved it👍👍😃

[@teagzy07]

While he's looking at a way he can help which is very insignificant mind you we need to go to the source of the problem actually mining and using phosphorus we need to do stuff like use organic fertilizer and actually solve the problem instead of slow it down

[@nahm0002]

You give a TedX talk as a geochemist to talk about vegan diet and food waste ? Anybody can do that. Where are the phosphorus deposits, how can we recycle it, what should we grow.

[@RealEstateInsider247]

There is no shortage of phosphorus. See my other comment. It is a just matter of time before every concerned person is aware of this.

[@JCrow-kz4nw]

We have 40 to 80 years worth unless we get lucky and find new reserves. Technological recovery is going to involve the Second Law as are many possible recoveries. Ahem.

[@wobblybobengland]

Second law of motion or thermodynamics?

[@suphaters]

@@wobblybobengland TY. That's what I wondered too.

[@Alexander_Kale]

No, we don't. We have in between 40 and 300 years left at CURRENT prices, depending on when our demand peaks. And after that, we don't run out of Phosphorus, far from it. At that point, we will continue mining Phosphorus, the price will just go up when we move to the next set of deposits.

[@marcozolo3536]

@@Alexander_Kale So are you factoring in the influx of supplies from space? Because 40 to 300 years is a long time for markets to adjust to space mining.

[@Alexander_Kale]

@@marcozolo3536 Not entirely sure what you mean here. The deposits I mentioned are all terrestrial and chances are, mining stuff in space will remain more expensive than anything we can do down here for quite a while

[@JacobBanuelos]

I thought it was an interesitng talk, it is a pitty the sound is terrible (it is far away with lots of echo), but they should change the title to how I became a vegetarian. It does not talk AT ALL about the phosphorus crisis, and he being a geologist, I thought it was going to become interesting. Pitty

From “phosphorus is essential for plant growth” to not eating meat 🤔🥴 there’s a better way to raise meat.

[@stillwatersfarm8499]

Lost me when you said meat won’t fill you up, lol. Some of us find we consume *far* less food when we eat meat.

[@fkrabberod]

@Still Water Farm , He was making a comment about how 70% of phosphorous in his diet came from meat, but meat did not equate 70% of what fills him up throughout a day. In other words, there are alternative ways of filling yourself up that does not have such an intensive use of phosphorous

[@stillwatersfarm8499]

@@fkrabberod Yes, I watched the same video you did. My point is it takes less food volume to reach satiety with meat than with plants.

Big brain time: the answer to all our farming needs can and very well may be aquaponics. Someone SS this and share in 10- 60 years when the world realizes. Thank me later 😜
