Since humans have made many horrendous things we will easily agree on some things we would want to change in humanity. Yet, at some point, it’s difficult to define exactly what would be better … what would be more “productive” as you wrote.

So the quality of soil is most important…

Yes it is possible … but this factor is difficult to measure, as it may go both ways, depending on motivation to learn new things and if that AI is a good teacher or … is giving ready-made (and bad) answers without helping to go further.

Because i agree with this, i encourage you to push this idea further to its conclusion.

i did it often enough. Now someone else did it for me and I’m very happy they did.

P.S. : Often it’s not my ideas but the harsh direct way i express them 😆

ok. You mean i type : “goal ?”
instead of “goal?”
… well this is because i have poor eyesight … and i want to see the “?” clearly.

Good tricks 😁
(Yet on my keyboard, “space” and “LineFeed” are way quicker to type.)

Yes. Thanks for stating these hard facts.

Present day atmosphere is about 400 or 450 PPM compare this to :

CO₂ poisoning (Hypercapnia) https://en.m.wikipedia.org/wiki/Hypercapnia

→ Physiological effects :
A high arterial partial pressure of carbon dioxide ( Pa CO₂ ) causes changes in brain activity that adversely affect both fine muscular control and reasoning. EEG changes denoting minor narcotic effects can be detected for expired gas end tidal partial pressure of carbon dioxide (…) increase from ((53,000 PPM)) to approximately (…) (66,000 PPM = 0.066 atm). The diver does not necessarily notice these effects.

Yes absolutely (and i was afraid to say it out loud).
But now, we have also to explain why it did not so much apply in the past millennias … or tens of past millenias. (again, i am afraid to say it … don’t want a shitstorm)

i agree that some aggregate of all of these, and to various degrees, and differently for different people, would apply. Also, i did not say more so to let the discussion open.

Lead was a much bigger problem in the 1970 when it was in road vehicles fuels. But now its only use in some small plane fuels. There is also much less use of lead paint and lead in water pipe systems.
N.B. : Study in that article is about decline from 2010 until today in 15-year-olds.
