Dear colleagues,
we all know that humans
consider themselves as the smartest species on planet Earth -- it is true,
although it is also true that we are making a very bad use of this great
intelligence in order to kill each other and members of other species as well.
Pretty dumb, I'd say.
But how is it that we are so intelligent? It is a
question that has puzzled me for a long time and, by now, I think I have a
possible answer. You can find it here:
https://www.qeios.com/read/IKNUZUMy point is that
large brains are possible only in conditions in which they can be efficiently
oxygenated; that is for low concentrations of CO2 in the atmosphere. It is a
condition that Earth's ecosystem experienced only during the past few million
years. And that is why we are here, basically.
Unfortunately, no
matter how smart we think we are, we are dumb enough to be working at raising
the CO2 concentration at levels at which the brain cannot be properly
oxygenated. We may be "un-evolving" ourselves, back to times when there were no
sentient being on Earth. The recently observed phenomenon of "global dumbing"
may be a first indication of what's happening. Obviously, that makes even more
urgent to stop emitting CO2 -- it is a problem additional to global warming, but
perhaps even more worrisome.
So, if you have some time, please take
a look at my paper. For the time being, it is in the form of a preprint, and I
am waiting from comments and criticism from others before I submit it to a
scientific journal as a full-fledged paper. Your comments, suggestions, and
criticism are most welcome
