August 1, 2023 - Circadian Rhythm, Climate Change, Nationhood, Slavery Misrepresented, and Nostalgia Quiz #4

 

                              * * * 
Night and Day

When Cole Porter wrote the lyrics to ‘Night and Day,’ he was not thinking about what is known as the ‘circadian rhythm’ that governs most of what happens on our planet. Some scientists define it as the physical, mental, and behavioral changes that follow a 24-hour cycle. These natural processes respond primarily to light and dark and affect most living things, including animals, plants, and microbes.

The way things turn out, the Earth’s rotation on its own axis and its year-long voyage around the Sun result in a permanent condition whereby half of the planet is in light and half of it is in darkness, with some borderline twilight conditions, periods we call dawn and dusk, and some lengthening of the periods of night or day nearer the North and South poles.  But over the course of a year, that evens out too.  Our planet is intended to be evenly split, day after day, year after year, between light and darkness.

Humans always played by these rules, working during daytime and sleeping during nighttime.  Fireplaces and candles provided some minimal leeway, but these habits were generally followed until about a hundred and fifty years ago, when Thomas Edison invented the light bulb.  That changed everything, enabling us to turn darkness into light, and nighttime into daytime.

Edison and his invention


That worked out fine for us, electric lighting enabling working and social activities to extend into evening hours, roadways to be made safer, night baseball to supplant day games, and produced vast areas of artificial light, such as the Las Vegas ‘strip,’ illuminating our planet as never before.  Satellite views of the dark side of our planet reflect these vast areas of ‘light pollution.’  You can see them from a plane if you are flying at night.

Unfortunately, as beneficial as this might be to us, it is disastrous to other creatures, insects, plants, and even microbes with which we share the planet.  This ‘light pollution’ disturbs their feeding, mating, and migratory habits to the extent that some species are becoming extinct.  Humans were designed to be daytime creatures, whereas other species are able to do things in darkness based on visual, auditory, and sensory abilities far different, and often superior to ours.  (The giant squid has eyes the size of dinner plates, so as to be able to spot its predatory enemy, the sperm whale, a great distance off, even in the darkness of the ocean depths, something human eyes cannot do.)

For many if not most species, these activities take place during darkness, some of which they are deprived of by our turning nighttime into daytimeThe crucial mating habits of insects that are prey to other insects that might pollinate a plant or be a food source for other creatures along the food chain, including humans, can be drastically changed. Without being able to mate and reproduce, they are on the path to extinction. Have you ever wondered where many of the beautiful butterflies you remember from years ago have gone?

And plants that provide food for us can be similarly affected by our taking darkness, a period of rest for some and activity for others, away from them. And the same holds true for the inhabitants of the seas, from microbes on up to whales.  Do you like to eat seafood?  Those delicious lobsters and shrimp fed on something that fed on something, that fed on something else that would not have survived without darkness.

This past week, to reduce light pollution on my small piece of property I have turned off the lights that illuminate the plants and trees in front of my house, just leaving the two bulbs adjacent to the garage door working.  I hope our local night-loving creatures will appreciate that. 

(Inspiration for this piece comes from ‘The Darkness Manifesto’ written in 2020 by Swedish scientist, conservationist, and writer Johan Eklof, whose field of expertise is ‘bats,’ creatures who prefer darkness to light.  It’s an easy book to read, with nice, short, not particularly technical chapters.)

Climate Change is Upon Us

And continuing the theme of the previous article in this posting, the bad news is that climate change is no longer a threat to prepare for.  It is upon us already, right now.  The hot weather and forest fires throughout the world are no longer just warnings.  They are indications that climate change has arrived. There are many reasons for this but let us just touch on one. 

Emissions from the use of fossil fuels (coal, petroleum, even wood) to produce energy have contributed to raising the surface temperature on the planet.   We know that energy resulting from the use of wind, solar, tidal, and even nuclear, sources can reduce such emissions but our conversion to these alternate sources just hasn’t advanced sufficiently to avoid our present changing climate. 

New Yorker Magazine 7/31/23 Cover


The increase in the planet’s temperature has, for example, caused the Greenland icecap to begin melting.  This is raising the level of oceans worldwide, causing flooding, and mixing fresh water from the icecap with the seas’ salt water, reducing the density of the water in the oceans.  As a result, colder waters, formerly comfortable at the seas’ bottom, can rise to dominate ocean currents.  Scientists foresee this potentially doing away with, or changing the paths of, ocean currents such as the Gulf Stream, which plays a large role in the weather systems bordering the Atlantic Ocean.  Less rain in North America, affecting agriculture significantly and a frigid coastline are possible results.

As the Hanging Gardens of Babylon once might have
appeared, before episodes of climate change took place.

Areas of the world that once were verdant have become almost desert-like as the result of climate changes in the past.  It would be presumptuous to believe that such change cannot again occur. The least we can do is to stop contributing to the changes that clearly are already taking place.

Nationhood and The Problem in Niger

Landlocked Niger, not to be confused with Nigeria.  

I have always felt that there are certain prerequisites of nationhood, more specifically (1) logical borders such as mountain ranges or bodies of water, (2) natural or human resources sufficient to support a viable economy, (3) an ethnic, religious, or linguistic commonality of its population, making it distinct from those of neighboring areas, and (4) a sufficient number of educated people, dedicated to and capable of, effectively managing it as a nation.  When thirteen of England’s North American colonies chose independence in 1776, they easily satisfied all four of these prerequisites.

It appears to me that lack of even one of these, however, can lead to instability and a neo-colonial dependence on outside powers, or a takeover, usually claimed to be, but rarely is, temporary, by whoever controls the military or by the military itself.

This seems to be the problem in Niger and elsewhere in Africa, if not the world.

Slavery Taught Skills – Pure Bullshit

Florida’s change in its educational curriculum for teaching history has reached a new low by stressing that slavery offered slaves the opportunity to learn skills.  Even if after emancipation, such skills turned out to have been helpful for some, using this argument to help sugarcoat the awful truth about a brutal system that treated human beings as ‘chattels,’ to be overworked and beaten, and bought and sold, totally ignoring family relationships, is horrible. It denies that slaves were human beings, equal in their humanity to their supposed ‘masters.’ 

'... And you can teach her to cook and sew too'

If this revelation is disturbing to any of Florida’s high school students, as some narrow-minded ‘moms’ may feel, that would be a  good thing for them and a long overdue awakening.

Any person of color, or anyone for that matter, who votes for any of Florida’s shameless legislators who supported their governor’s inhuman approach to history, would have to be out of their minds.
