What calamities? I believe that we have the engenuity, science and technology to overcome almost any calamity that may come. Population overgrowth is certainly a major problem, especially in the third world.
While a lot of the sustainability marketing is BS, there's plenty of small ways in which we each can make an impact.
Let's take clean energy, for example. New nuclear fission reactor designs that cannot melt down are coming online in this decade. Much more efficient with less fuel. These commercial designs will be built around the world. The uranium pellets that are coated in a special material do not require cooling after removed from the plant.
Even with regards to fossil fuels, new plant designs capture and reuse almost all carbon produced by the plant.
In the next two decades, commercial nuclear fusion should be a reality. 100% clean energy without the use of radioactive material.
By the end of this decade, Toyota expects to have an electric, solid state battery that can go over 600 miles and recharge in 15 minutes. Solid state batteries don't carry the fire risk of lithium ion batteries. Once this solid state battery is reliable over long distances, electric cars will be feasible to the masses. The distance limitations and charging times are what kept most people from considering an electric car.
All of that is just on the energy front. In terms of reducing future emissions, and having sustainable clean energy, I think we are closer than ever to being there.
Which ones??
All the calamities that originate in small mistakes or ignorances that snowball.
Small mistakes that -unnoticed, unaddressed, and unmitigated - go on to become bigger mistakes. Then those bigger mistakes - un-admitted, unexamined and uncorrected - go on to become calamities. For better or worse, the USA is still the greatest - at least in terms of sheer power, if no longer moral/philosophical leadership - nation on earth. Still... we've been riding on our mythical laurels for quite some time now. We have become lazy. We have become dull. We have become self-satisfied and self-deluded. We have grown uninformed. We have allowed ourselves to become misinformed. All of this makes us extrememly dangerous.
We have grown fatuously enthralled with "disruption" as a solution while blithely ignoring even the question of what the problem was we were out to solve. LOL. We have become deluded with savior fantasies around our technological prowess - a prowesss that is growing ever more weak and applied ever more self-servingly. Even if our technology
could save us -which in some cases is true- it won't until utilizing technology for good becomes more profitable than using it to sell more ads for more ridiculous consumer-products (damned near all of which will come wrapped in multiple layers of plastic).
We have suffered over a half a century of proudly checking out. Proudly getting rich, not paying taxes and forgetting that we all live in community. We have become a nation that glorifies idiots who fly a private jet from, say, a luxury house on a beach in Michigan, to drink an umbrella drink in a ticki bar near a beach (not
on a beach mind you - that's too sandy, too windy, and too filled with sand fleas) in Florida... or Tahiti, because drinking the same drink far away is somehow a more fulfilling experience, or at least a more invidiously distinguishing one.
We have suffered half a century of the exaltation of self and privatization over -and to the exclusion of- a sense of community. A half a century of the degradation of the free press. Almost 3/4 a century of ever growing hatred of public education consequent with the diminution and disparagement thereof.
There are much cheaper ways to defeat freedom and democracy than using guns and bombs and tanks. The easiest way is to dumb down voters so, thereafter, you can cow them into defeating themselves. How do you do that? Label the free press as "the enemy of the people." Eliminate public education. Create a public with no common sense of themsevles as a people and no real knowledge of their own history. Create an average public that actively and aggressively pursues distraction, ignorance and insanity.
Little things lead to big things. This underlays the Swiss cheese approach to understanding airline calamities. This approach also applies to understanding most other man-made calamities.
If you don't know
what calamites are currently -
right now- essentially unavoidable givens, blame that on the same culture/tax-free-magical-thinking-shrine/education that leads folks to
engenius spellings of "ingenuity." That's one of those small mistakes or ignorances.
