Man the answers are all over the place on this one. Maybe because what your asking sounds more like a philosophy question . Plants can absorb nitrogen from the air btw. I'll assume you are asking why they can't turn it into protein. The short answer is they absolutely could but lack the genes for it. Why can't you turn sunlight into sugar? Why can't we breathe under water? The answers to questions like this is that we don't know for sure. Evolution took the paths it took and here we are. Maybe it's not worth the bother to plants when they get enough nitrogen from bacteria or lightning strikes. Another part of your question involved farming. Farmed plants are not natural. We use fertilizer to increase the yield, but those plants will still grow without fertilizer.

I've lived in MN my whole life and the coldest I remember was a few overnight lows of -30F during a polar vortex. I think some areas in greater MN might have hit -40F here and there but it's certainly not routine and doesn't stay that cold very long. Anything lower than say -10F is not common and usually only for a few days to a week or so.

I think perhaps OP was implying that the lack of REM was likely to have played a role in what led to his death, inability to sleep seemed to be the reason he asked for the drugs in the first place 🤔 it would only worsen his mental state from there, requiring more and more to even just achieve sleep alone, which just isn't enough ☹️

most of it is simply the result of the analog production process, and the losses inherent to each step. so you basically overshoot with bold colors so that it still looks decent at the other end.

older cartoons were produced with cells and photographic film. in that process you are literally blocking or transmitting light through both the cells themselves and the film both at the time they’re photographed and reproduced and eventually transferred to whatever electronic signal, which back then was also analog and had its own transmission loss.

every part of that process will result in a loss of both detail and ‘dynamic range’ so to speak because trying to pass a light through something while also having it be opaque is a conflicting process.

add into it all the other hand production methods, cell paintings, the relative quality of transfer technologies at the time, and yes the fact that its end was to show up either on a low res tv screen or a movie screen, which although capable of high detail theoretically, between multiple showings, flicker, and reproduction also be degraded.

in addition each color beyond just a flat reference color requires more attention to detail to keep consistency between artists etc.

we really take for granted how much the digital process has opened up for art reproducibility in the last 30 years.

I don’t like to give my location but I live near Edmonton, so very dry and cold.

I don’t know Fahrenheit very well but a cold night here will maybe be -30C, with maybe only a week where the temperatures dip below -40C. I mean without windchill (since we are talking about pipes freezing indoors).

I checked the average low temperature for January for Minnesota before posting, and it said the average low was around 4F, so I figured I was fairly close to around what the average low temperature was.

Yes, lots of bright sunny winter days here, too. But, I can tell you guys aren’t much warmer than us despite being so much further south…those midwestern winters are brutal!

What part of Canada? I think we get and stay colder than most of the East and Great Lakes areas. We're further North than Toronto even.

Every year in Jan/Feb we'll get a week or two with nightly lows of -40 to -50 or so. Sometimes the daily high even stays below -30F for a week or two. Bright, sunny winter days are a special thing - too cold to snow!

There are some great books on this and the ancient side of the development is a good start but things got really cool when industrial extraction got started properly.

The ventilation shafts of old stayed but then extensive systems of flaps operated by actual children took hold. Still, that was not what limited depth of mines. The desire to get clean burning coal eventually forced people to deal with large amounts of water that would seep down. The first steam engines were primarily designed not to move the coal, but for the more challenging subject of removing water from mines.

Also the canari was for finding noxious gases. The presence of flammable gasses was detected by having people walk into a mine with a long pole sporting a candle at the front. These goal was to burn the so called fire-damp before the rest of the workers were at risk.

All in all mining has always been a crazy world, Coal by Barbara Freese is a wild book to read if you’re interested in this world at all.

It amazes me they still let them run it.

200 mph down extremely long straights that are not maintained to a standard that most tracks are kept at.

One of the famous motorcycle medics was killed a few years ago too. It's shocking that the only way to have a reliable medic on the course involves them in either a high end 911 or a bike.
