Impossible?

If you find the following extract tantalizing, definitely follow the link "Final Empire" on the side column of this blog:

"The consensus assumption of civilization is that an exponentially expanding human population with exponentially expanding consumption of material resources can continue, based on dwindling resources and a dying ecosystem. This is simply absurd. Nonetheless, civilization continues on with no memory of its history and no vision of its future.

Possibly the most important source of life on this planet is the thin film of topsoil. The life of the planet is essentially a closed, balanced system with elements of sun, water, soil and air as the basic elements. These elements work in concert to produce life and they function according to patterns that are based in the laws of physics, which we refer to as Natural Law.

The soil depth and its richness are a basic standard of health of the living planet.
As a general statement we may say that when soil is lost, imbalance and injury to the planet’s life occurs. In the geologic time-span of the planet’s life, this is a swift progression toward death. Even if only one per cent of the soil is lost per thousand years, eventually the planet dies. If one per cent is gained, then the living wealth, the richness, of the planet increases. The central fact must be held in mind of how slowly soil builds up. Soil scientists estimate that three hundred to one thousand years are required for the build up of each inch of topsoil.

The nourishment of the soil depends upon the photosynthetic production of the vegetative cover that it carries. There are wide differences in the Net Photosynthetic Production of many possible vegetative covers. As a rule it is the climax ecosystem of any particular region of the earth that is the most productive in translating the energy of the sun into the growth of plants and in turn into organic debris which revitalizes the soil.

A climax ecosystem is the Equilibrium State of the "flesh" of the earth. After a severe forest fire, or to recover from the injury of clearcut logging, the forest organism slowly heals the wound by inhabiting the area with a succession of plant communities. Each succeeding community prepares the area for the next community. In general terms, an evergreen forest wound will be covered by tough small plants, popularly called "weeds" and the grasses which hold down the topsoil and prepare the way for other grasses and woody shrubs to grow up on the wound. ("Weeds" are the "first aid crew" on open ground.) As a general rule, the "first aid crew" - the first community of plants to get in and cover the bare soil and hold it down - is the more simple plant community with the smallest number of species of plants, animals, insects, micro-organisms and so forth. As the succession proceeds, the diversity, the number of species, increases as does the NPP, until the climax system is reached again, and equilibrium is established. The system drives toward complexity of form, maximum ability to translate incoming energy (NPP) and diversity of energy pathways (food chains and other services that plants and animals perform for one another). The plants will hold the soil so that it may be built back up. They will shade the soil to prevent its oxidation (the heating and drying of soil promotes chemical changes that cause sterility) and conserve moisture. Each plant takes up different combinations of nutrients from the soil so that specific succession communities prepare specific soil nutrients for specific plant communities that will succeed them. Following the preparation of the site by these plants, larger plants, alders and other broadleaf trees will come in and their lives and deaths will further prepare the micro-climate and soil for the evergreens. These trees function as "nurse" trees for the final climax community, which will be conifers. Seedling Douglas Fir for example, cannot grow in sunlight and must have shade provided by these forerunner communities.

The ecosystems of this earth receive injury from tornado, fire, or other events and then cycle back to the balanced state, the climax system. This is similar to the wound on a human arm that first bleeds, scabs over and then begins to build new replacement skin to reach its equilibrium state. The climax system then is a basic standard of health of the living earth, its dynamic equilibrium state. The climax system is the system that produces the greatest photosynthetic production. Anything that detracts from this detracts from the health of the ecosystem.

Climax ecosystems are the most productive because they are the most diverse. Each organism feeds back some portion of energy to producers of energy that support it (as well as providing energy to other pathways) and as these support systems grow, the mass and variety of green plants and animals increases, taking advantage of every possible niche. What might be looked at as a whole unitary organ of the planet’s living body- a forest or grassland- experiences increased health because of its diversity within.

On a large scale, the bioregions and continental soils substantially support sea life by the wash-off (natural and unnatural) of organic fertility into aquatic and ocean environments. This is a further service that these whole ecosystems perform for other whole ecosystems.

A few basic principles of the earth’s life in the cosmos have now been established. Balance is cosmic law. The earth revolves around the sun in a finely tuned balance. The heat budget of the planet is a finely tuned balance. If the incoming heat declined, we would freeze or if the planet did not dissipate heat properly we would burn up. The climax ecosystem maintains a balance and stability century after century as the diverse flows of energies constantly move and cycle within it. In the same manner the human body maintains balance (homeostasis) while motion of blood, digestion and cell creation, flow within it.

The life of the earth is fundamentally predicated upon the soil. If there is no soil, there is no life, as we know it. (Some micro-organisms and some other forms might still exist). Its vegetative cover maintains the soil and in optimal, balanced health, this cover is the natural climax ecosystem.

If one can accept these few simple principles then we have established a basis of communication upon which we may proceed. Anyone who cannot accept these principles must demonstrate that the world works in some other way. This must be done quickly because the life of the planet earth hangs in the balance."

Much of scientifc research in the 19th and 20th century has concentrated on 'finding our identity'in this universe and understanding how this delicate ecosystem operates (the likes of Darwin, Einstein). Yet, in some ways, what this implies is that the so called 'civilized' world is not able to bridge the gap between 'knowledge' and 'awareness'. And translate that further into a moral obligation for our own actions. Probably at our own peril. Now we understand much and do little to change things!

I presume it may have something to do our human-centric philosophy. The irony of things is that although now we do UNDERSTAND that we are not the centre of the universe, and that we are only a part of a complex ecosystem, it certainly hasn't changed our approach. As in the middle ages we still seem to THINK we are the centre of the universe, we BELIEVE in the supremacy of the human race; and that everthing has been created for us to use, abuse and destroy!
