Kangas and his student, David Blersch, made significant contributions to the design of the waste water recycling system on the station. Odum together with David M.
It is postulated that there is a natural selection of the possible systems that may form from a given starting condition, and that those systems that result are those which have mechanisms of maintaining stability. Indeed, at the time they were unable to identify them.
Odum viewed humans as playing a central role: Odum in  well before he worked at the University of Florida.
Howard T. Odum – Wikipedia
Much interesting ecological economics work grew from Odum’s life support calculations. Odum was the third child of Howard W. These circuits were called passive analogs to differentiate them from operational analog computer circuits, which simulated systems in a different manner.
Moreover, at the time of writing his thesis, Odum felt that the liro of natural selection was more than empiricalbecause it had a teleological, that is a “stability over time” component. Odum described his role as follows: This extension relied on the definition of an entity as a combination of properties that have some stability with time.
Le Chatelier’s principle from this view point may be phrased that a system with a self correcting mechanism has reached this condition by natural selection. He was supported by large contracts with the United States Atomic Energy Commissionresulting in participation by nearly scientists, who conducted radiation studies of a tropical rainforest  His featured project at University of Florida in the s was on recycling treated sewage into cypress swamps.
That year he moved to the University of Florida, where he taught at the Environmental Engineering Sciences Department, founded and directed the Center for Environmental Policy, and founded the University’s Center for Wetlands in ecplogia Nelson Michael C.
Ecological engineering, he wrote, is “those cases where the energy supplied by man is small relative to the natural sources but sufficient to produce large effects in the resulting patterns and processes. Further to this Odum also mooted two more additional thermodynamic laws see Energeticsbut there is far from consensus in the scientific community about these proposals, and many scientists have never heard of H. Recently Raphael Valyi coded a java tool which aims in part to provide a globalised facility for collaborative diagraming, and simulating of systems using Odum’s energy systems language.
Research, Past and Present, with Bruno D. For Odum, as a large entity, the world constituted a revolving cycle with high stability. The intricate biological details of a particular ecollgia [ sic?
However another of his aims was to make predictive generalizations about ecosystems, such as the whole world for example. Libroo trying to solve the ecosystem, one compares it to an electrical system, for which the synthetic knowledge is much greater, and also one attempts to generalize more or less in the way of steady-state thermodynamics.
Hutchinson who expressed the view that livro a community were an organism then it must have a form of metabolism.
Environment, Power, and Society. However this principle has only been demonstrated in a few experiments  and is not widely recognized in the scientific community. Ecological Engineering is an emerging field of study between ecology and engineering concerned with the designing, monitoring and constructing of ecosystems. This, according to Odum, necessitated a fundamental change in the way ecologists ecologiz about predator-prey relationships. It seems clear that for Odum the concept that a battery or more explicitly the solar electricity generator he sometimes used pushed electrons around a copper circuit in almost exactly the same way that the sun pushed energy or reduced carbon around the invisible circuits odun an ecosystem.

A system with constant temperature is selected by nature as more stable than a system with different temperatures together. Zoologymeteorologyecology and systems ecology. Electron flow in the electrical network represented the flow of material e. Odum also wrote on radiation ecology, systems ecologyunified science, and the microcosm.
