Earthlings Letter #5 – “Still Life”…Let’s Talk about Rocks!

Jeff & Susan • June 19, 2015

Greetings Earthlings!  For a while we are going to leave the lively strutting of life that photosynthesis makes, the plants and animals and us, and take a look at the ‘still life’ of rocks.

Rocks!  One of my favorite things on Earth.  Those objects that just sit there and don’t go anywhere, but they contain all the mysteries of our Earth’s history.  Believe it or not we started to think about rocks when we were examining dirt. Yes, one ingredient that makes rock is soil.  Plants and animals are not the only things that are dependent on soil.  At some point in the development of the rocks we call ‘biologic (related to living things) sedimentary rocks,’ they were soil.  Soil, that is made from the decay of plants and animals, became this kind of rock.  Some very ‘young’ rock of this type you can pick up and easily break apart with your hands.  It is little more solid than dried mud.  Older sedimentary rock is ‘solid as rock’.  This happens because of the way that these rocks form, over millions of years.  To understand how they are formed we must understand what activity the word ‘sedimentary’ is naming. 

 You studied sediment when we examined soil in the first Earthlings Letter.   Sediment was what settled to the bottom of the jar of water into which you dropped a soil sample.  The word sediment comes from a Latin word, ‘sedimentum’, that means ‘a settling’.  If you have ever observed a chicken getting ready to rest you will have noticed it’s process of settling and finally staying in one place, very content.

The Latin word, ‘sedere’, is also a root of the word sediment and it means, to sit.  So what we are noticing, in the case of sedimentary rock formation, is particles of decayed plant and animal matter drifting through water till they finally settle on the bottom of the river bed, ocean, lake or whatever, and stay put.  Over lots and lots of time, (millions and millions of years) many, many layers of organic matter drift and settle and create pressure by their weight on the layers below them.  Also, the pressure of the water above them is added to this and compresses (makes them flat and thin) the layers, finally making the deposits under the most pressure, in the lower levels, bond together into sedimentary rock.

Now, I mentioned that rocks contain the mysteries of Earth’s long existence. Let’s see how we can start to ‘read’ this story in rocks.  Sedimentary rocks are some of the easiest to read.  They can sometimes even have messages stamped right on their surfaces!  We say that these rocks have ‘fossils’ in them.  First, I will define ‘fossil’ then we are going to do an experiment.  A fossil is the remains of an organism preserved as a mold or cast, in rock.  This word comes to us from the Latin words ‘fodere’, to dig and ‘fossilis’, dug up.  Now let’s do an experiment.  All you will need is a piece of clay or damp mud and an object of your choice that you can easily hold in your hand.  Now form your clay or mud clump into a ball maybe three inches or so across.  Press the object you chose into the surface then gently pull it away.  You will notice that the texture (The way something looks or feels on it’s surface) of your object has left its impression in the clay.  This is called a mold of the object.  And if you were to fill that mold with plaster, let it dry, then pop it out, you will have made a cast of your object.

 I have a collection of fossils that are both molds and casts.  They are mostly ancient clams and some plants.  I have been able to find these because 3 million or more years ago or so there was a part of the Atlantic ocean covering where I live today.  Many kinds of clams lived in that shallow sea and died there and were covered by sediment, layer after layer.  The pressure of these layers acted like your fingers pressing an object into soft clay.  The object disintegrated but its impression remained, ‘set in stone’.  

So how can we read these fossil stories?  We must slow our selves down and pretend we have ‘all the time in the world’.  And, by the way, this is how much time rocks have had to develop!  A trick you can do to slow yourself down and observe in different ways is to close your eyes.  The information we get from our eyes is wired directly to the words we have been trained to use when we refer to objects we see.  So often we leap to the word that will describe ‘in general’ (very simply) what we are looking at.  We don’t linger and let ourselves make discoveries that the ‘namers’ may have missed!  When you close your eyes you are activating other senses that are excellent observers but are often taking back stage to the ‘star’, which is sight.  So, chose a rock that interests you and if you can find one with a fossil in it, great!  Now, hold it in your hands and close your eyes.  Let your rock tell you things about itself through your sense of touch,  how rough or smooth is it, how cold or warm.  See if scratching it with your fingernail will break pieces of it away.  This will tell you something about its age and what it is made of.  Observe through your sense of smell, is it an earthy smell, a metallic smell, or sulfurous, etc.  If you wet the rock this can bring out the scent of it more clearly.   Even your hearing will give you clews about your rock, for example, if you hear a stream near where you found it, flowing water could have helped it form.  Start to open your mind to all the possibilities and activities of nature in the area where you found your rock and you will begin to piece together in your imagination what has formed it to its present state. 

Here is what I have observed, about a rock I am holding, that has a fossil cast in it, with out using my sight to help me.  I know, it is very hard not to cheat and look!  The first thing that I notice while I hold the rock in my hands is how cold it is.  So I start to think about why it is cold.  We understand that sedimentary rocks are formed from small bits and particles under massive pressure for a long time.  These particles are forced very close together and create what we refer to as a dense object..  The denser an object is the longer it will stay cold or hot.  It takes longer to heat up and longer to cool down because each of the particles of the rock has to give up its portion of hot or cold in order for temperature change to happen.  And there are so many of these particles in the rock!  If my rock had been sitting out in the sun it would be warm.  It is cold because it gets cold during the night.  And it will take a while for it to warm up when the sun shines on it.  Even a rock that is warm to the touch may still be cool deep inside if you were to break it open. It still has the coolness of the night inside it.  And did you know that rocks move!  When it heats up it expands (gets bigger) a little and when it cools down it contracts (gets smaller).

Next, I smell the rock and it smells earthy.  This tells me that it is made up of mostly decayed organic material and is a ‘young rock’.  Only millions of years old!  Finally, I begin to feel the cast of the fossil.  There is a special kind of writing that is called ‘braille’ and it is used in books for people who cannot see, so that they can read.  This writing is made up of raised groups of dots, each one representing a letter in the alphabet.

In this way words can be punched into paper so that a blind person can read them with their finger tips.  I am going to try to read the ‘braille’ of Earths alphabet in the fossil form under my fingers.  First, I feel ridges that radiate from a central source.  The overall shape is not quite round,  it swells a bit like the surface of an egg and it is mostly smooth and feels longer than it is thick.  Since I know that I found this fossil where there used to be an ocean, I can guess that it is an animal that lived in the sea and protected itself with a shell.

A drawing of a pearl with a face on it

It is the shape, of a once living creature turned into stone, that my fingers ‘read’.  And this is just the start.  One answer leads to another question and another answer and another question and on and on…   Our Earth is alive in countless ways and life causes change and change creates more questions for us to think about.  There will always be some thing new for you to try to figure out!   So, if  someone says to you ‘those are just a rocks’, you can reply,  ‘they are not just rocks, they are capsules of earth history.  And they tell us wonderful things!

Returning to Caron, Philippines. Several miles off shore, while passing the Island of Borneo, we observed a surreal sight. Stationary skeletal structures on the horizon, some of them with flames shooting from a long up tilted pipe, like a dragon breathing fire. These were oil derricks 30 or more miles from the coast of Brunei burning off natural gas, a volatile by-product of oil drilling. They come into view, are left behind, and new ones appear, as we progress. At least 30 derricks paralleled our course. Normally there is nothing to see except an occasional container ship. So this is exciting. I read that there are at least 200 of them in this vicinity. Also, some have been decommissioned and made into marine habitats, (dismantled and sunk), by the Brunei government who deploys and maintains these derricks. They are a major exporter of oil and share the Island of Borneo with Malaysia and the Philippines. This experience of observing oil drilling activities during an oil crisis feels a bit surreal.

The approach to Coron, Philippines. Mountains all around, some narrow cream colored strips of beach. Single person open boats drift here and there, some are paddled. The larger colorful outrigger boats glide by like water spiders, leaving no wake. Clouds have bunched and swelled above the land taking up a lot of the sky blue sky. This is the rainy season. Our ship is drifting slowly. We are not expected at port for a while. The opening of the harbor is in sight and a green entrance marker is visible.

In its present form, Capitalism cannot easily fix the ongoing problems of its own making. It has become an economic formula for much of World commerce. Its empowerment of the often unrestrained pursuit of profit, guided by the optional moral consciences of some individuals, businesses and nations has allowed for broad interpretation resulting in vast destructive behavior. We have been able to personally visit about forty countries during more than a year of continuous travel. Our goal is to complete one circumnavigation within another two years. This trip has developed into a unique opportunity to research World economies. Which was our hope at the onset. We are now in Southeast Asia and it is possible to make a few observations. The opening of ‘free markets’ with Capitalism worldwide has become a modern form of Colonialism. Countries that are thriving go into developing nations with the huge advantage of currency value and technological superiority. They essentially locate in each country resources that can be monetized and profit made, hire employees for less than they can in their home countries, then take the majority of the profit out of the host country. This dramatically changes the existing natural balance in most of these developing countries and thrusts them into the financially unbalanced world of free market capitalism for which they are not prepared and have no immunity. Where we have traveled so far, many developing countries are turned into tourist attractions and the young people are mostly encouraged to aspire to ‘hospitality’ work, keeping their expectations low. The following is a short summary of how Capitalism has evolved in recent history. People have benefited for many hundreds of years from the innovation and competition inherent in the practice of Capitalism. But now the symptoms of its flaws are obvious and too damaging to ignore. When Capitalism fails from its own weaknesses it can, in its final form, become fascism; dictatorial power, militarism, an autocracy that crushes opposition. It makes a few people very rich and creates a dictator to protect their wealth and influence resulting in an ultra nationalist state. When a country is completely invested in Capitalism, like the US, it must constantly monitor its military and financial power in the World. Looking back; the US petro dollar was established during the 1973 energy crisis by Nixon/Kissinger, in order to keep the US dollar strong next to other currencies. Controlling the high value of a nation's currency is essential for Capitalism to thrive and it was clear that oil was the blood of World economies. Arab oil traded for dollars in exchange for US military protection was the deal with the Saudi government. Because oil energy is a major labor saving device and creates exponential productivity and wealth, trading dollars for oil made the US Dollar the “preferred currency” and kept its value high. In 2024 the agreement with Saudi Arabia expired because the US could no longer protect Arab nations militarily. Also the rise of renewable energies challenged oil supremacy. One of Capitalism’s characteristics is to concentrate wealth in the hands of a few and encourage profit making over stabilization of a good quality of life for the rest of humanity. Over emphasis on profit making has suppressed education, healthcare and general dignified survival wherever it dominates. Wealth is not a barometer of intelligence or happiness. It is an advantage in Capitalist societies that opens opportunities in education and business. All it takes is a few powerful people to keep Capitalism going, apparently the richest 10% of the World population. That Capitalism has lasted so long is in part a testimony to its ability to keep adapting and improving on its least attractive strengths: control over the means of production, control over the value of currencies, amorality, exploitation, and a powerful military. Capitalism is presently a pervasive economic belief system and acts as a powerful temptation and World influence. Its social impact is on par with Communism, Democracy, Religiosity, Socialism, Liberalism, Conservativism, etc. This has again been made clear by the present oil/food crisis, created by the US/Israel attack on Iran that resulted in Iran closing the Strait of Hormuz. (Was this war a move on the part of the US to control oil and keep the USD strong?) This situation may already be worse than the energy crisis in the 70’s that created the US petro dollar. The World population is larger and more interconnected economically than ever before, making this oil shock even more damaging than the one in the 70’s. Oil is a valuable fair trade commodity. Its locations and price are controlled by a handful of companies and nations. (A common characteristic of Capitalism.) This essential energy source is centralized and vulnerable. The World economic system is in shock and being held hostage to the flow and price of oil. But this time there is a competitor for preferred currency, China's Yuan. Humans have become, over approximately 500 years, adapted to Capitalism. It feels inevitable, no matter what it destroys. It has captured the popular imagination like a religion. But unlike religions it encourages people to cast aside concerns of morality and the fate of humanity. Its symptoms and failures are explained away as the evils inherent in humanity or individual failures. But religions have shown they can evolve. Economics can evolve also. Like the worm of Protestantism that entered the apple of Catholicism, maybe there is a pest that can invade the Capitalist feeding frenzy. This pest could be in the form of a Parallel Currency, that would create, in time, a hybrid World economy dedicated to the dignified survival of all humanity. Any nation or state could introduce a Parallel Currency to be used next to existing currency. A currency printed to provide a base for humanity; the essential needs of life; food, shelter, education and healthcare. Not freedom, not security, but what comes before humanity can have either of these things, survival. Life long access to food, shelter, healthcare and education. There is enough. Basic needs are the least expensive and most abundant things a nation can provide its citizens. The Parallel Currency is a way to pay for it. A few countries are already trying to do this with their tax structures and laws, but a Parallel Currency would do it without taxation or inflation. With a stroke of a pen it can be initiated. It is a separate currency that can only be used for basic needs; their creation and distribution and is destroyed when it reaches a bank so it won't create inflation. It also will not inhibit the positive capabilities of existing currencies. They will function normally. The Parallel Currency would be a closed loop created for dignified human survival. A form of this is already used by the major developed nations to supply and sustain their large militaries. You are provided food, shelter, education and healthcare as long as you are employed by the military. China has built, in its isolation, a successful hybrid of Capitalism and Socialism controlled by its Communist government. In approximately 40 years they have brought their massive population out of poverty and become one of the most technologically advanced nations on the planet. Freedom of speech, freedom of religion are not enough. A government by the people, for the people, must also guarantee freedom from starvation, homelessness, and freedom from ignorance and curable illness. All things for which we have, as a human species, developed remedies. This is the overarching injustice of Capitalism. That these remedies exist and have been largely made possible by Capitalism but are not shared with all humanity. People have evolved beyond the war response to disagreements, but governments have not. By eliminating the tensions created by economic inequality with a Parallel Currency dedicated to providing survival needs Worldwide it is possible to see a new way. It is our responsibility to help economics and governments evolve with us. Susan Caumont Renew the Earth, renewthe-earth.org

They have only recently become independent; 2002. The struggle and tragedy of this objective still vibrates in the air and has left scars. Poverty, deteriorating roads and sidewalks, buildings and ambitions. In the intense heat of the day, most shops can't afford to have or to turn on air-conditioning. A large tree shaded park where an unchained warrior statue shouts to the sky, is heavily used by all ages.

Our arrival on the island of Waingapo is welcomed with a red carpet. The carpet leads expectantly to where several men wait, holding 11” by 14” laminated photo narratives of tours they can take you on and tell you about with three word comments in English. Past them chairs, also covered in red, have been set up under an awning for our “dignitaries.” Beside these are a few tables with souvenirs. Several young boys wait on either side of the red carpet to perform for the passengers as they disembark. Many local people are also waiting in the growing heat for the Exodus of the passengers. Ours may be the first cruise ship that has stopped at their island. One passenger finally emerges and avoids the carpet and the boys. They are shocked. Eventually a group does come out together and allow themselves to be greeted and entertained. They have selfies taken with the boys. Then return to walking and looking into the screens of their phones, bowed over them like they are praying After exiting the port area there is a long walk through parked cars, trucks and taxi drivers out to the crumbling asphalt of the main road. It is lined with vendors, a gauntlet of drinks and snacks. A ferry is unloading, people and motorcycles are streaming out. These are the customers the vendors are waiting for. A large number of motorcycles are parked on either side of the road waiting for their owners. We make our way between the crowds of people and vehicles to the hot uphill slope of the road that goes somewhere, which is hidden from sight by bunches of dark green trees. Shortly we are defeated by the heat and start back. Access to other parts of the island that are considered appropriate for tourists require a taxi, negotiations for price and where it will go. Generally we try to avoid this and are most interested in what we can observe and who we can meet by walking. We talk to a motorcyclist on our way back who says he has access to local Royalty. Jeff describes the Parallel Currency concept to him and gives him our website card. I am also able to pick up some interesting scraps of paper from the garbage that lines the road. I use their patterns and color to create abstract images on postcards I make to send to friends and family. In the end this has turned out to be a very satisfactory walk. There are very few palm trees here, which is remarkable. A different ecosystem than Bali. The mountains are low, flat topped and shelved. They define the spine of the island. Bunches of dark green trees patchwork the slopes getting denser as they approach the water. The water is blue/green and clear, fishing boats are high prowed and the smaller boats have outriggers made of bent PVC tubing. It is now early evening and the sun is low. I am walking around the outside deck of our ship taking in the 360 degree view and the sounds. On the starboard side a band is playing on shore and a singer starts up a contemporary tune. As I round the bow a chant drifts through the dusk, the Muslim evening prayer. This dominates the port side then at the stern blends with the music on shore, which dominates on the starboard side. Round and round as I walk they alternately blend and retreat, blend and retreat. I notice as I look out over the port side that the tide has gone out and long flats of seaweed, rocks and soil are exposed. People have walked out onto these surfaces to harvest edible sea life, gathering them into plastic buckets and bags. I feel like I am watching history.

We dock at the port of Bali. It is too hot and far to walk anywhere, so we hired a taxi driver for the day and invited our friend Wido to come with us. He is Indonesian, his home is in Jakarta and this is his first visit to Bali. Indonesia is a country of 17,508 islands. There is a governor on each one who communicates with the central government. Few Indonesians have visited every island. What strikes me immediately as our driver, Budi, finds his way through the dense traffic, is the careful weeding of the center island between opposing lanes. This is exceptional because of the extreme heat. No one could be doing this during the day. People must come out at night, when it is cooler, and meticulously pull the weeds. It becomes clear as the day passes and more and more of Bali is revealed, that attention to detail and extreme patience is a characteristic of the Balinese. The traffic is a dense mix of motorcycles, cars and trucks.

Like an exotic jewel set in the archipelago of Indonesia, Bali glitters and enchants. The Balinese have retained their unique community through intense social/religious bonds, hard work, exceptional talent and great sacrifice through the centuries to become a beautiful, gentle and inspirational community. Now, because of these unique qualities and accomplishments, finally and fatally they have become a primary tourist attraction that presently dominates 80% of their economy. The irony is that this may be the thing that destroys an incredible place and its people that hundreds of years of oppression and wars did not. If they don't soon diversify and return to the trusted systems that meant survival for their society over more than a thousand years Bali will no longer be a wonder of the World. Their unique form of Hinduism understood the root of survival when their irrigation system, subak, was first built. It was defined as a religious object to be venerated and protected with prayer, with temples and maintained by priests. Rooted in the Balinese philosophy, Tri Hita Karana, the principle of achieving harmony between humans, nature and the divine. It was the source of the staple food, rice. Water came from lake Batur, in the crater of the extinct volcano Kintamani, irrigated the hand cleared and formed terraces of rice paddies that descend in beauty and function to the sea. Seedlings hand planted by the women, sheaves of rice attached to the ends of poles carried across the shoulders of the men to the storage huts simple activities, carried out over more than one thousand years, that meant survival for a society. And the ancient kings of Bali also came together to sanction the subak. Agreement between religion and state. A rare thing in history and in the present. So what is happening now? How is tourism threatening the survival of the Bali we have come to know and admire? Aren't people coming to praise and enjoy? Isn't that a good thing? It is not the intentions of the visitors, it is the structures built around tourism that make tourism possible, they have become destructive. Why are they destructive? The answer is water. Because of the demands of hotels and resorts for fresh water, the water table has dropped by around 60%. Into the void presses the salt water of the sea. Not only is the amount of fresh water that feeds the subak compromised it is threatened by salination and made unusable for rice growing. This situation is sometimes referred to as being caught between a rock and a hard place. The government needs to step in and limit or freeze new construction of resorts till a sustainable balance is found. Also, water use needs to be prioritized and rationed for essential use, the subak system as a primary user. Finally, the income from tourism must be distributed back to the Balinese people for their dignified survival and flourishing. The dependency on tourism has created an imbalance. Men can be seen sleeping rough in the parks. There is desperation in the eyes of the women who sell clothing and souvenirs in the outside stalls. The main profession encouraged for children is hospitality work. The majority of profit from tourism needs to be returned to the people. They have earned it, they have built what we admire, they have carried in their hands and hearts the unique social compromise that has survived to this day against impossible odds and now it is being challenged by economic forces, more subtle but no less aggressive and destructive than war.

Sea days pass differently than land days. At sea the ocean and the ship's passengers are the changing features. Land life has extra distractions, vehicles, shops, museums, temples, churches, gardens, bird song, dogs barking, taxi drivers, venders, airplanes, the full extent of human activity. During sea days I prefer to observe the ocean. I am aware of the passengers; like being part of an extended family or small village where you know most of the people a little and a few well. But the opportunity to be on the water for long periods is special. Sometimes, when the ocean is calm, a criss-crossing pattern may be seen on the surface, a delicate weave of vibration. I wonder if marine life is creating it, communicating. Other times the water heaves and agitates like an angry crowd is running here and there under a silk sheet. We sail six days from Adelaide to Fremantle, for the most part we encounter easy swells on this trip. The ocean lets us pass with tranquil, breathing heaves up and down. When we arrive there is an art festival in progress downtown. Crowds of people have traveled by train from the suburbs. We walk in. Some streets are blocked, making way for displays of crafts, performers, food venders and pedestrians. People are all around, eating, talking, buying stuff and watching the performers. Clowns, singers and acrobats compete for attention and overhead huge soap bubbles float, generated by the children nearby. It is a perfect day and everyone is out to have a good time.

Our stop in Melbourne was only for a day. There are plans to return after we visit Tasmania, which is just south of Melbourne. When you look at a map you can see where the island broke from Australia, a ragged triangle torn from the continent. England brought their convicts here to establish a penal colony in 1803, (convict transport ended in 1851, 50 years later) the colony eventually became Hobart, the capital city. Convicts were brought by sail. All the way from England around the southernmost tip of Africa, Cape Agulhas. A cape historically known to clipper ship sailors as a significant hazard, notorious for mammoth rogue waves of up to 30 meters (100 feet). What could these unlucky people have done to be banished on such a dangerous trip and so far away to an “uncivilized” island? Turns out prostitution and unwed pregnancy was enough to get sent there if you were a woman. And being an orphan, if you were a child.

The yellow pilot boat is approaching. A pilot will be brought onboard to guide our ship through the harbor. As we progress, a stretch of islands pass us on the left then, the coastline, on both sides. Sailboats, white triangles against the dark blue water, shine in the distance. Cliffs drop sheer from the pastureland to the tan beaches. Dark green groves fill the crevasses. We cruise along under the dome of the sky. Soon we will be docked at Port Melbourne, Hobson's Bay, Australia. Living life onboard, traveling around the world, I feel like a spirit watching the living as they go about their activities. I am a temporary exhalation, undetected then gone. But their doings remain in my mind. Humans are so very busy, especially the young adults. It takes significant aging to bring on stillness and reflection. My obscurity can make me sentimental. I feel a general affection for anyone who passes. I saw a baby watching sea gulls eat the French fries that someone had tossed to them. I imagined her forming her own impressions of everything around and not yet named. I wished her well and hoped that the war would end soon.
