My view is that building artificial biomes is an undisputed human practice, and the 'megacity' suggestion is a future history of an established trend. One known side-effect occurs when pollutions from various intensifications enters the food chain and directly impacts fertility - Chernobyl is a case in point.Possibly. The thing is the trends show decreasing fertility rates as countries develop.
This is particularly true in some east Asian countries like China (although this is skewed by the one child policy), Singapore and Japan, which have birth rates around <1.6. It seems that as education increases, particularly among females, there is a tendency to favour careers over 'family lives'. This can create tensions as its against certain cultural norms of what the female role is....
There has been little indication that advancements lead to increased birth rates again. But I guess the things you are theorising are quite unprecedented, so who knows!
Helsinki (AFP) Aug 27, 2007 - Twenty-one years after the Chernobyl nuclear disaster in Ukraine, fish and mushrooms in parts of Finland are still toxic due to radioactive fallout, Finnish authorities said on Monday.
I agree that there is an inverse correlation between education and birth rates. The cause, in my view, is a concern for humanity. Our minds can be described as having three loosely connected layers between which communications can be compared to long-term nagging. These layers are sometimes named visceral, emotional, and reflective:
Example: Visceral powers our basic reactions to the environment, like our impulse to breath and reproduce. Reflective is where I view education having greatest impact as it stimulates self-reflection on emerging dilemmas. Note: brain drawing repurposed and the emotional section could be better placed.
My view is that education generates a positive feedback loop that powers life-long learning, and life-long learning has no time for visceral reproduction - highlighting an obvious dichotomy. WHO has, for over a decade, reported that 'major depression' has been the leading cause of disease in women and "the burden of depression is 50% higher for females than males". Could the dichotomy in modern life be the root cause of WHO findings?
I see intensification advancing humanity towards autonomous intensive farming (e.g. lab grown meats), designed by societies that continuously educate themselves in all disciplines. My view is that our drive to overcome exogenous bounds on population size undermines our ability to accommodate the fundamental visceral needs of life! 😱
