I guess we'll have to replace it "Artificial soil: quick and dirty" https://www.newscientist.com/article/mg19526161-700-artifici...
Requires a subscription. 'Replace it' is a little imprecise here, allowing for substitutes. I'm sure some people are trying to make substitutes but we know a lot more about how soil becomes these days and we're able, to an extent, to create it by introducing food to the right food chains. Unfortunately for perennial crops, you have to build that food chain up orders of magnitude more than you do just for annual plant…

We don't have any "responsbility" to anyone or anything but our own desires.
You may not have loyalty, but if you're enjoying the fruits of society there is also responsibility to that society, otherwise one should probably extricate himself from society and see how long he makes it in the woods without it.

I love this comment :) Messing a bit with drops in the ocean is how we got here in the first place. Aggressive farming messes with the environment a bit. There is just so much land, we can't possibly deplete all of it. Did you see how much air we have? Yeah burning dirty stuff pollutes it, but then the wind blows and it's clean again.
> There is just so much land, we can't possibly deplete all of it. Given that we are currently using 40% of the world's land area for agriculture, and that we are using ~0.0003% of the world's water, I don't think this is a fair criticism of my post. Only a fool would think that former isn't something to keep an eye on. > I love this comment :) Messing a bit with drops in the ocean is how we got here in the first pla…

> Modified meme caption: Yea, we destroyed the environment, but for a brief moment, we sure mined a lot of Bitcoin. It's hysterical that Bitcoin is the punching bag, because when economies that are prone to hyper inflation give way, its BTC that is used in many of those same countries. Who also, resort back to subsistence or local Ag. And guess what, destroying your land is kind of antithetical to the whole farming t…
I agree that Bitcoin is too easy a punching bag, but "we found a lot of hashes with leading zeros" didn't have the same brevity to it. I am open to wondering if CO2 emissions are also too easy a punching bag. Crops can go way nonlinear when lacking mined water, lacking fertilizer, and lacking soil/biomes etc. I was not aware that the infrastructure bill favors regenerative Ag.
It's pretty vague, to be honest; but from what I've gathered many of its proponents are using it as a phase-in from the core of the New Green Deal, and is essentially a massive works project.
As a former farmer (Biodynamic) myself and a person that did Supply Chain I think that critical infrastructure doesn't just apply to the roads upon which freight travels on, also having a horrible factory farmed centralized food system is what created shortages during COVID and were revealed for all to see. There is no denying it that this model cannot function with just the slight amount of variance, 3PL continued to work and even improved during COVID in some industries, but none of that mattered in the end.
This incidentally led to crop losses due to a lack of labour, and many unnecessary deaths of workers like at meat packing plants had a shocking enough effect that made CSA memberships (shares in the Farm that grant you boxes of vegetables) the more viable option and revealed something that I knew from experience in the aforementioned industries (also culinary): the less food travels, the more savings can be passed on to the consumer, but also the higher a premium it has to it's targeted demographic.
The reason I highlight this is because critical infrastructure, as in the stuff that is of national security, after COVID has to include manufacturing of things like PPE and medical equipment as well as farming in a far more distributed manner--ventilators were just one of the examples of how far the US had fallen.
And the truth is the Department of Ag already has a lot of sound programs to help young, first time farmers: but a concerted effort to incentivize them with low to no interest loans for farming equipment and livestock for 10+ years would be a boon for so many wanting to get into farming and revitalize so many disenfranchised communities that were displaced in the 80s when mega pharmacorps forced their way that led to this big Ag system.
Simply removing a lot of subsidies to corn, soy farmers and using that to float the low interest loans would pay for itself in added revenue, moreover many farmers markets are now obligated to accept things like WIC and foodstamp programs to be accepted so we can readily pivot a low income community's diet in a decade, as seen in Detroit.
I'd include water/desalination as well, but to be honest I'm not sure that will be explored this go around, but may at a later time.

#276Tangentially related, I want a dataset of all cultivated lands and what crops they are growing? Is there a dataset for it? I mean, I give GPS coordinates and I get back crops growing there.
You want the Cropland Data Layer from USDA/NASS. 30m resolution, updated yearly: - https://nassgeodata.gmu.edu/CropScape/ - https://www.nass.usda.gov/Research_and_Science/Cropland/Rele... - https://developers.google.com/earth-engine/datasets/catalog/...

General data is in government reports. The farmer who owns that GPS coordinate has it, but considers it sensitive data and won't tell you. There are big databases, but they respect the farmers not wanting to share and won't talk. The admins of those database are registered with the SEC as having inside information and so they cannot trade in relavent markets.

I see it as a conjunction of the two. Science is a good tool for getting things done. The how. Money is the motivation for getting them done. The why. You've both got good points. Scientific capability enables fucked because money.
It's very curious to me, the connection between science, mind, learning, and economy. They are all optimization processes; narrowing the gap between the model of the world and the actual world, with science being a method of modeling and validating models, a method of learning. Minds are collections of learned models, and economy is the actualization of those models to accomplish the acquisition and use of resources.…
When it comes to evolution, individual organisms are needed by the thousands.
If we have one superorganism subsuming the whole planet, then what if it turns out this isn't the ideal evolutionary path?
