Speak louder than words

Healthy planet, anyone?

It’s years since I visited Oakland’s Museum of California – now known as MOCO – and learned that bees sang for their supper. Put another way, bees, upon alighting on a plant – sing an appropriate song to induce the plant to release its nectar and feed the bee
Now, I learn that bees scream when attacked by murder hornets  A recent study:
… published in the Royal Society Open Science journal… revealed that bees release a “rallying call for collective defence” against the hornets. The previously undiscovered signal, now known as an “anti-predator pipe, shares acoustic traits with alarm shrieks, fear screams and panic calls of primates, birds and meerkats”…
Bees produce the sound by vibrating their wings or thorax, elevating their abdomens and exposing a gland to release a pheromone.
. Will humans learn the even a fraction of what makes our wonderful planet tick before we destroy all of nature?

More amazing critters. Took these pix with an actual camera on my walk today.

Water

News blues

With further travel in my imminent future, digging through current travel requirements and restrictions is a fulltime job.
The CDC’s website “operationalizes the President’s “safer, more stringent international travel system”.  The US White house’s website offers an outdated executive order, “A Proclamation on the Suspension of Entry as Immigrants and Non-Immigrants of Certain Additional Persons Who Pose a Risk of Transmitting Coronavirus Disease” 
New details emerge on travel to the US, including from South Africa:
Beginning Nov. 8, foreign, non-immigrant adults traveling to the United States will need to be fully vaccinated, with only limited exceptions, and all travelers will need to be tested for the virus before boarding a plane to the U.S. There will be tightened restrictions for American and foreign citizens who are not fully vaccinated.
The new policy comes as the Biden administration moves away from restrictions that ban non-essential travel from several dozen countries — most of Europe, China, Brazil, South Africa, India and Iran — and instead focuses on classifying individuals by the risk they pose to others.
It also reflects the White House’s embrace of vaccination requirements as a tool to push more Americans to get the shots by making it inconvenient to remain unvaccinated.
Accordingly, given my vaccination status, I’d be cleared to travel to South Africa – well, pending negative results of my pre-travel Covid test. But I worry about clearance to return to the US in the spring. My current life is a balancing act: property and family responsibilities here in California and property and estate/family responsibilities there, in South Africa.
Responding to those responsibilities in South Africa seems like a no-brainer… except for Covid. Covid, the Great Unknown.

Healthy planet, anyone?

Water. A non-renewable resource.
Did you know that there's as much water today, as there was thousands of years ago? Actually, it's the same water. The same water supply has been circulating throughout the world for ages. In fact, the water from your faucet could contain molecules that dinosaurs drank!
How is that possible? Through the amazing Water Cycle as nature's way of constantly meeting water demand with water supply.
We depend on fresh water from two main sources - surface water and ground water. Surface water is the water found on the earth's surface such as oceans, lakes, streams, rivers, ponds and reservoirs. Of all the earth's surface water, 97 percent is too salty to drink because it's located in oceans and seas. Another 2 percent is locked in ice caps and glaciers. Only about 1 percent of the earth's water is fresh water to be used for agricultural, commercial, manufacturing, community and personal household needs.

Meanwhile, back at the ranch…

Living in the conurbation of San Francisco Bay – population 7.75 million – means many choices of lifestyle. My choices include living modestly albeit close to water… near a marine preserve with miles of shoreline I explore regularly on foot.
Today’s exploration included the western portion of Ballena Isle, looking toward San Francisco. These photos (taken on my cell phone) don’t do justice to the Bay, nor do they give a realistic view of just how many cargo ships populate the Bay, awaiting service – unloading or loading - at the Port of Oakland… due to the ongoing supply chain backup.
I’ve walked this area multiple times over the years. Today was my first visit since returning from South Africa in early June.

More cargo ships awaiting service at the Port of Oakland.

An altar of small treasures.

The marina  on this side of Ballena Isle, home to some 200 boats of different sizes and shapes, looks about the same.
The big change was to the garden used by the marina’s life-aboards. What was once patchy and somewhat unkempt has morphed into a lovely, artistically groomed Eden, clean, swept, and full of small treasures.

I met Peet walking Dave, her very friendly pit bull who, by way of greeting, slobbered over my trousered knees. During our friendly conversation, Peet explained she – and her husband and Dave – lived aboard their trawler. Surprise! I’d believed live aboard lifestyles were a thing of the past in San Francisco Bay. I learned that it was still possible – theoretically, right now, in my hometown, to live aboard one’s boat. Peet advised I approach the Harbor Master to “get your name on the two year’s long waiting list but get on it anyway…”. The waiting list wasn’t a surprise. Moreover, two years on a list for a slip is no hardship right now when I no longer have a boat.
At the Harbor Master’s office I got caught n the Catch 22: One can only get on the wait list if one already has a boat in that marina – that, presumably, one does not live aboard. But why would I have a boat in the marina if I wasn’t living aboard?

Turned out, also, Peet is a self-employed muralist. She volunteered to paint a mural painted on the wall of a storage container at the marina garden.
Note the brown pelicans, once endangered, but making a comeback in this area...

Spectacular, aren't they? Note how Peet incorporated the actual tree (top left) into the mural.
