The error in this thought perhaps lies in the way they concieve it.
Most population, more peoples..... they envision as perhaps a thing growing in a petrie dish that means more chance for survival of that species. More more more. Deaths will ensue but so many of us are there we will persist.
The truth of this is... it is like a forest. A forest left on its own with natural fires, weeds out itself and continues healthy and strong.
With no fires, when a fire eventually does occur(which will happen), the result is all trees in that forest die. The fire becomes so large and aggressive it consumes everything in its path down to the dirt itself.
Humans with overcrowding to the extent it is headed, do in fact ensure they the humans will not persist as species. As fire will persent in some form of fashion. I'd suppose as global warming, consequent to that, but that is conjecture.
Quite unfortunate and tragic as they serve as the best means to enlightenment of all that may be found in these realms. Other worlds sure...but to lose but one is a great great tragedy, if it has not to be that way, which it does not.
A lack of scope and consideration of how things are it seems.
They are for all intents and purposes prevented from seeing this thing and the present danger.
Me in my own ideocyncratic way..... do believe in demons. The demons in my cosomology of this world do eat humans in a fashion.
I do expect the demons/gods may step in at some point to, with unrelentless point, show this thing must be remedied.
If not they will go quite hungry eventually with no human to eat. NOt a overtly stupid lot are they(just samsarically stupid).
So in my personal fashion I guess I am not all that thinking.... gross tragedy will ensue in this place.
Those that may have influence may do so. Perhaps they are..to my superficial knowledge and very limited understanding it appears that is exactly what is displaying at the present time. In New Mexico the heart and foundation of all things nuclear is at we speak Los Alamos being threatened with total destruction by forest fire. It being now totally evacuated.
If demon I would do exactly this type of thing. Or inversely this is just the start of the consequence of a faulted ideology.
I don't know having not this in my field of study
