Home alone

News blues

Plummeting Covid-19 case counts across the United States are leading to lifted mask mandates and more conversations about steps toward normalcy — but more people are dying of the coronavirus now than during most points of the pandemic.

The pandemic is following a very predictable and depressing pattern. As with diseases such as malaria and HIV, rich countries are “moving on” from COVID while poor ones continue to get ravaged.

War!:
Not focused on Covid-19 … but meet Fiona Hill, my hero since I watched her uncompromising and forthright testimony during Donald Trump’s first impeachment trial. (Video clip from that time >>)
Fast forward to March 3, and Fiona Hill and Stephen Colbert chat about her dinner with Vladimir Putin, Russians protesting Putin’s current war, and the invasion and demolition of Ukraine and Ukrainians >>  (9:28 mins) 

Nuclear weapons:
For more than 30 years, one very good friend has engaged the reality of nuclear weapons and nuclear power: that they’re no good for people or planet. This friendship makes me sensitive to the topic – and very fearful of Putin’s putsch into Ukraine. These days, ridding our planet of nukes – weaponry and power generation – should be in the forefront of all humans’ minds.
The consequences of nuclear war would be devastating. Much more should – and can – be done to reduce the risk that humanity will ever face such a war.

Healthy planet, anyone?

Scientists have doubted whether the process of evolution can create “prudent predators” able to avoid extinguishing their own prey – and therefore themselves.
But “wild life” predators must avoid overexploiting their prey if they are to survive. They cannot evolve to become so aggressive that they eat all their prey and then go extinct themselves?
Why – and how – have they “done” this?
Read “Animals have evolved to avoid overexploiting their resources – can humans do the same?” >> 

Meanwhile, back at the ranch…

Last night was my first night, ever, alone – well, with three dogs – in my late mother’s house. (After a year of barely any time off, our domestic worker took the weekend off to attend a traditional Zulu wedding. This includes a cow meeting its demise and its peeled and dripping skin drying out over a fence while the edible parts are consumed with gusto).
Locking up the house last night was an adventure. I discovered where are the “weaknesses” … noticed which locks are tenuous, which exterior lights need attention….
Unlocking this morning was an adventure, too. Under the watchful eyes of hungry dogs, I managed this laborious task then doled out breakfast.
For the next 3 days, I’ve arranged my weekend to ensure the appearance of constant human presence in the house. This, to discourage unexpected incursions. (That thuglet who threatened my life still haunts the neighborhood, albeit mostly sleeping in local bushes as he sleeps off drunken episodes. I keep an eye out for him and opt to prevent incursions from the gen pop, too.) 
This weekend will be replete with painting walls, gardening, hedge clipping….
A year ago, I perseverated over purchasing a mechanical hedge clipper to trim the many hedges around my apartment. While this fecund vegetation affords privacy - one of the reasons I chose that apartment - one afternoon manually clipping presents reality: I can’t do this regularly. Reluctant but practical, I put aside ambitions of designing and cutting shapes - waves? Animals? People? - and contemplated the glory of mechanical clippers.
Alas, the selection of such tools around here is narrow: most clippers are too big and powerful for me - or too small and not powerful enough.
A friend swore by her small, battery-operated clipper, but I wasn’t enamored of the manufacturer and avoided that brand.
Hedge clippers were the last thing on my mind after I departed the country last year and attended to the demands of Covid-19.
A year later, those privacy-presenting hedges tower over my apartment garden. They desperately need clipping. I haven’t the appetite manually to clip them. Moreover, the many hedges in my late-mother’s garden need clipping too.
Rekindling interest in the perfect mechanical hedge clippers, I comparison-shopped in three local stores, saw little that enticed, returned home to the reality of overgrown hedges, and grappled with my dilemma.
I returned to one store, listened again to Vision, the salesperson, and focused on one brand. All the men with whom I consulted about mechanical clippers steered me away from purchasing a battery-operated set: “battery-run tools are limited”. Nevertheless, I purchased a battery-operated Stihl brand tool that perfectly suits me.
How did I settle on it?
The petrol (“gas”) fuel clipper offers a rope pull. After months struggling to start my small gadabout-boat motor with a rope pull, I swore never again tug anything with rope pull.
For my late mother’s large garden, the electrically powered versioin requires a very long extension cord (cost about R1000,00/US$65). And it would lie in/near water while I clipped. No way I’m risking electrocution if water intruded into the electrical system.
The set I purchased has a battery designed to run for up to two hours. Since I work 30-to-45-minute sessions, it should work. It’s lightweight enough for that duration session, too.
Back home, I charged the battery, inserted it, and clipped.
The device is 95% perfect for my size and strength. The 5% that’s imperfect? It struggles to cut long, sword-shaped, densely packed leaves. I’m a soupçon disappointed, but perfection is rare in a single garden tool. (After all, it’s the hunt for perfection that sends gardeners back to garden stores and allows tool manufacturers to generate profits.)
I’m chuffed with my almost-perfect mechanical hedge clippers.
What fun!

Super-slog Saturday

Another day of watching election results... with not-so-bated-breath. At least We the People (with discernment) appear on a trajectory for No More Trump….

News blues…

The US presidential election is taking up so much mental, emotional, and political space that coronavirus has faded into the background for the moment. Let’s review climbing infection rates:
  • United States: breaking records day-by-day - 100,000 and more cases of new, confirmed infections - per day
  • Italy: Much of Italy is now under lockdown, after the Covid-19 death toll for 24 hours hit 445 - a six-month record.
  • Spain: The total number of COVID-19 fatalities in Spain shot up on Wednesday by 1,623, according to the Health Ministry, bringing the country’s official death toll to 38,118… and 297 deaths confirmed since Tuesday, which is Spain's highest daily jump in deaths since April.  
  • Canada: battling its second wave of coronavirus infections; public health officials in the country’s western region are growing concerned as cases surge to new daily records. Active coronavirus cases in Alberta have quadrupled in the last five weeks. British Columbia, with 5 million residents, notched up more than 400 new cases.
  • France: registered a record 60,486 new confirmed coronavirus cases on Friday, following the previous high of 58,046 on Thursday…
  • Brazil: reports 18,862 additional confirmed cases of the virus in the past 24 hours, and 279 deaths from Covid-19. The country has now registered 5,631,181 cases since the pandemic began, while the official death toll has risen to 162,015,in the world’s most fatal outbreak outside the United States.

A coronavirus-centric joke to alleviate anxiety after the dispiriting stats shared above. 

Healthy futures, anyone?

How does fracking work? 

Meanwhile, back at the ranch…

After spotting an unusual accumulation of vegetative debris on my doorstep – I took a closer look: it had a caterpillar-like head that retracted as I watched. I waited for the head to reappear and, when it did not, I photographed the critter.
The photo shows the critter’s rear end at the upper portion; Are those two shiny dots on the lower portion of the photo its caterpillar-like eyes?
Internet research suggests this unique creature is a bagworm, in the caterpillar stage.  Gatherings of bagworms, alas, can wreak havoc on trees

Mulberry season! 
Mulberries – elongated blackberries or raspberries that grown on trees rather than bushes - seem to have gone out of culinary fashion. Mulberry trees are classified invasive in the United States, but mulberry trees are alive and well in this neighborhood, and in this garden.
Monkeys are in mulberry heaven.
Monkeys are in apricot-and-plum heaven, too, as apricot and plum trees producing new fruit. But the fruit is still hard, green, and only marginally larger than marbles. Monkeys don’t care: they’re plucking the premature fruit and, usual for monkeys, taking one bite then tossing away the rest of the fruit.
This bite-and-toss behavior upends my general acceptance of evolution: how come, given many generations of monkeydom, monkeys have never figured out that leaving fruit (and vegetables) to mature is a better nutritional bet than destroying them in infancy?
Oh, wait! I forgot. Humans descended from monkeys/apes… and we’re an impatient lot, too. Humans, like monkeys, are unsuccessful at anticipating how our current (stupid) behavior affects our future (healthy) future. (Think climate change denial….)
