Can we solve our current energy crisis in an ecologically friendly manner? Can we gain better understanding on ecological systems when viewed from a technological perspective? The answer is a big yes but only if our intellect is up to the challenge.
Ecology, the branch of science that deals with the interactions of living organisms and their environment, a term derived from two Greek words which mean "the study of the home" while technology is the totality of the means employed to provide objects necessary for human sustenance and comfort.
Since humans are the dominant "life form" on this planet, and are viewed as the cause célèbre for all of our ecological problems. Paradoxically, it is us that can only solve the problems that we create in the first place. One of the problems that we face today is our increasing demand for energy generation that is not necessarily environmentally friendly to begin with.How we go about solving this must go hand in hand on how we will protect our environment just to keep our planet habitable in the future. All the energy that mankind utilizes, whether renewable or not, all come from nature. Only a handful of scientists like R. Buckminster Fuller view ecosystems as an interrelationship between matter and energy or more aptly living organisms and energy.
All ecosystems are governed by: "The Laws of Thermodynamics", this is the relationship between matter and energy in a system. The First Law of Thermodynamics states that "the sum total energy in a system is constant" i.e. energy can neither be created nor destroyed. The Second Law of Thermodynamics states that there is a tendency toward entropy or maximum disorganization of a structure and the loss of usable energy.These laws prevent us from formulating an easy solution to our energy problem in an ecologically friendly manner. But first, let's check out how nature manages energy to sustain an ecosystem.
In autotrophic based ecosystems, the energy that is stored through net primary production by photosynthetic organisms is used to support higher trophic levels. Energy flows only one way through these levels with decreasing amount at each level. The energy that is captured by the autotrophs (photosynthetic plants) does not revert back to the sun. And also; what energy that flows to the herbivore does not flow back to the photosynthetic plants, and so on, as it moves through the various trophic levels, energy is no longer available to the previous level. The important implication of this unidirectional flow of energy in an ecosystem is that the system would collapse if the primary source of energy, like the sun is cut off.
The next major fact to be noted is the progressive decrease in energy at each trophic level. This fact can be explained by the energy lost as heat in metabolic activity and manifests here as respiration. This particular ecosystem also has a large amount of unutilized energy. Even if more of this "unutilized energy" is being used in a more efficient system, there would still be considerable loss due to respiration. Thus, even with more efficient energy utilization, considerable energy would still be required to maintain the system.
These factors-Unidirectional energy flow and inefficient energy utilization-account for the requirement of a steady stream of energy to avoid the collapse of an ecosystem. An ecosystem simply cannot itself when deprived of a source of energy input for an extended period of time.
