The ancient Greeks believed that there were four elements that made up everything. These were earth, water, air, and fire. The powerful image of these are readily apparent when walking through our wilderness. They form a landscape which we call an ecosystem.
The feature image is a composite of the elements which make up the four elements of a world view that lasted for three thousand years of human civilization. This concept was not challenged until the 17th century, not questioned until the 18th century, not recodified until the 19th century and not defined until the 20th century. Yet, when walking through our wilderness, it is easy to see why the simplistic view was so persistent.
In previous posts you saw the following scenes during our explorations of southwest Florida. Notice that all observations were based on sand. The most frequently found life forms have been the plants. The Slash pines, Saw palmetto, Ferns and grasses. are the toughest most productive species. They may not be the first responders but they are always the last survivors. They may not be keystone but they may be the cornerstone species
There are commonalities among the ecosystems we have explored in SWFL. What we see are the four elements of water, sand, wind and fire. We looked at hardwood hummocks, flatwood pines and scrubs and beach pine ecosystems in SWFL. The dominant surface has been sand but this is a specific old sand that doesn’t stick together because of its blunt, rounded surfaces and corners. Water has also been a constant factor in all of these environments. It has ranged from swamps to marshes, streams and ponds of fresh water to high salinity coastal ocean water. The size and shapes of the sands and the plants which live in them has been shaped by wind and selectively cultivated by fire. In casual observation we may not be aware of it however, on a daily basis, they are all in constant flux.
Although geologically, climatically and biologically diverse, these observations are consistent with those made in other parts of the world including our exploration of the equatorial and central Africa, Central Europe, Central and South America, the subarctic tundras of Canada and central and costal China. They all have cornerstone species which are tough and prolific.
Our persistent global view of our environment is delusional. It seems constant and simple. This perception is in conflict with the reality of global changes that are revealed only with fact based uber-human insights. From discovery of subatomic structure and molecular biology to views of earth from outer space and massive data and computational power we see that our earlier concepts were so shortsighted. Geologic and fossil records suggest that life with RNA began 2 to 3 billion years ago. RNA/DNA is the ultimate survivor. It persists in its myriad forms and is the foundation of all life today. If we allow ourselves to have a humbling experience we can see that although humans are now the dominant animal species it is a fleeting, precarious existence where we are so vulnerable to extinction. The next most dominant animal species is insects. Unlike insects we use and abuse the resources with intention or without it. The insects with the plants which occupy this land have a remarkable vast history of slowly changing physiology and appearance. Over time, they mutate, procreate, selectively survive and change to meet the planet which in turn reciprocates the change. They are aware only of earth, water, wind and fire. Still, they will out survive us.
In the enormous scale of time, animal species and angiosperms have frequently changed. Birds and mammals which we enjoy today have developed only in the recent 65 million years since the last extinction; hominoids only in the last 1 million. In SWFL these plants are generally angiosperms like saw palmetto, slash pine, ferns and grasses including palms. The plants are quick to recover from wind and fire but genetically are very slow to change. They are the ultimate survivors with predecessors that date back hundreds of millions or perhaps a billion years almost unchanged. Some animals are ancient too, like the reptiles, insects and many marine animals. Relative to these ancient plant and animal species, all that we see alive today including humans are invasive species with which the plants have accommodated. We are continually faced with our own changes and that of the world around us. Of the species that are with us today, in time, most will disappear. The survivalists on land, like insects, gymnosperms, and reptiles will persist.
Interpretative summary;
Change is inevitable. Those who are able to accommodate to change are survivors. If the speed of accommodation to change is insufficient then to avoid extinction, the ability to recover from stress is imperative . There are some unavoidable extinction events. If you don’t like them, try not to create them.
So what:
We should rethink our relationship to the environment. We need to assimilate and cooperate with the changes. Resistance is futile. In a following post we will explore a futurist view of what will eventually be done. Evolutionarily the agent acting against physics and thermodynamics has been life. Life has survived by accommodating to everything during the last 3.5 billion years. Using the free energy from the sun, DNA collects and stores information, builds resources of energy storage and construction materials. With these it generates and executes algorithms that protect and promote self replication. For our survival we will do the same. This process is in our genes; in fact it is our genes.
