Extremely wrong how? There's a great an well sourced section in Vaclav Smil's How to Feed the World about this very topic. I also cited a specific erosion figure. But I guess that doesn't matter.
looking forward to reading it! definitely skeptical about your erosion rates, will have to go do my own research later (quick look, USDA estimates for the Corn Belt (~5 tons/acre/year on average)). if your info is coming from one book then i'm doubly skeptical, though i would bet that a soil scientist would probably agree with me and i'm def wondering if you might've misread the book?
i'm not a farmer, but i do manage woodlands, have a huge garden, volunteered on farms over the years, worked in a sustainable ag non-profit, and have even tried distributing sweet potatoes, etc, so i have an avid interest in agriculture and our food system.
aside from the fact that the soil is one of the three most important components for growing food, therefore it's extremely important to take care of it if we want our species to live into future centuries... there is a lot of evidence that shows that industrial ag creates erosion problems (one easy example: all of the national forests in my area was degraded farm land that they converted to woodlands in the 30s, because they learned this fact that hard way then). believing that hunger is a solved problem because of 20th century style agriculture is a fallacy. the dust bowl is one historical example that shows how this system can fail spectacularly, and it's all based in how we manage the topsoil, a natural resource just like oil or water.
we lost the moment we tried to overcome natural systems with chemicals (we've had a good run but i believe it's gonna be an anomaly in history). you can use science + natural systems in your favor to grow food. taking care of the topsoil is objective number one. food is a byproduct of good soil. the soil is a living system and chemicals kill that ecosystem to our detriment.
technology is definitely not the answer here. you are welcome to go try to grow food on mars without soil. good luck!
I initially copied the wrong number, the correct number is 1mm per year, coming from a Unas Amherst study not Smil’s book. It’s high vs pre industrial rates, but not catastrophic and as Smil points out there are plenty of places where land being farmed industrially is gaining soil.
glad we're working from the same figure now. 1mm per year is not insignificant, and soil is not a renewable resource... probably a fine amount of soil loss for a farmer's lifetime, but a land manager needs to think over centuries and not in profit cycles.
> and as Smil points out there are plenty of places where land being farmed industrially is gaining soil.
i would bet at least $100 this happens where they do cover crops and actually manage the soil as a resource to be preserved
Thats 1mm in the upper Midwest around the Great Lakes, wind is doubtless a factor. You can’t generalize to all industrial ag from a dozen sites in 3 geographically similar states.
Right, but tillage is not a set in stone practice. The Nebraska Corn Board is now advocating no-til corn planting[1]. Apparently it's already dominant in Western Canada and more than half of Montana cropland is managed without tilling.
Herbicide is a whole different discussion and probably too deep a rabbit hole so far down thread.
> This is like saying the real solution to bad practices of food companies is to exclusively grow your own food, or the answer to anti-repair practices is to only build your own devices, vehicles, etc. Contractors cut corners? Don't try to regulate, just learn carpentry, plumbing, and HVAC plus codes!
you're acting like these are bad or impossible skills to learn? these is just basic skills that people should have.
i'm one of these developers who found myself doing a lot of security-oriented devops work. how do i get away from compliance? i hate checking boxes, feels like it creates some pointless work sometimes. compliance alone makes me never want to do cybersecurity but i enjoy the architecture stuff and thinking about threats
> hate checking boxes, feels like it creates some pointless work sometimes
Everyone does. It doesn't actually help reduce tangible risk, but it helps you understand the operational and liability aspect of cybersecurity which is critical as well.
> compliance alone makes me never want to do cybersecurity
Compliance =/= Cybersecurity. If you work in an organization where security actually means compliance, then leave.

Honestly, it's region and industry dependent. If you are east coast, transition into a JPMC or GS tier bank (yes, banks are bleeding edge security personas).
If you are west coast, it shouldn't be difficult for a SRE/DevOps/Cloud type to become a SWE or Solutions Engineer at a cybersecurity company.
If you are in Europe, get an H1B and leave. I literally helped sponsor 2 O-1s today from European cybersecurity founders who wanted to leave becuase of subpar terms and bureaucracy.

i recently used gpt for the first time in several months (i'm a daily claude user) and didn't find this at all. it is most certainly trying to pull you into engagement with how it ends each response. "if you want, i could tell you about this thing that's relevant to what you are discussing and tease just enough so that you addictively answer yes"
my partner is working on a piece of software to predict late frosting for a data science company (it kills your seedling plantations, if you are into that sort of thing, i don't but sometimes the client wants it)
so i was considering adding that to qgis as the data is available freely.
