While I completely agree with your sentiment I think the explanation, the solution is much more simple.
We are indeed the most destructive elements, beings in nature’s fully integrated, interdependent system, by stubbornly forcing a “cancer-like”, unnatural, excessive, overproduction, overconsumption Human paradigm. By this we harm the natural environment and mostly harm ourselves, in fact even before the virus appeared we were already heading towards our own civilization-ending explosion, blindly repeating Human history’s recurring, vicious cycles.
You are right, there are multiple reports worldwide how even a few weeks of vastly reduced, harmful Human activity is enough for Nature’s system to repair itself, return to balance, homeostasis. But nature is not punishing us — we are punishing ourselves.
Nature is a closed, deterministic, lawful system, driven by a single evolutionary plan that drives the whole system towards integration, a mutually complementing, harmonious cooperation of all of its, vastly diverse, seemingly incompatible comprising parts.
If we do not follow the “iron laws” that govern the fragile balance, homeostasis that sustains life, optimal development we fail, self-destruct. For example, we know and respect the law of gravity, we know that if we jump off the top of a skyscraper we die. Still, we have been convincing ourselves for centuries that we can successfully ignore, go against the laws maintaining the balance in the system, although we also know that our own biological body stays healthy by the same laws!
Thus there is nothing mystical about what is happening to us today. Due to us spreading all over the planet, saturating our living space and also exponentially increasing our harmful, excessive activities we have reached the point where we punish ourselves with everything we do, as the system and its homeostasis can’t adjust, accommodate our activities any longer.
Forcefully reducing the Human population, trying to colonize other planets cannot help as our harmful, self-destructive program would not change by that. Nature will not change its laws, its system is infinitely greater, stronger than us. Only we can change!
Thus we need to find and implement the right, purposeful and practical educational method which can help us adjust, upgrade ourselves, the way we relate to each other, to the natural system in order to start solving our own, self-generated problems and safeguard our collective Human survival by becoming compatible with Nature’s system its laws.
