ECOSYSTEM AND THE BIOSPHERE: Metaphors for Human-Induced Material Flows by Rudolph B. Husar. Summary Report by Sarah Lahr ME 449 Sustainable Air Quality 2/4/02. Introduction. Natural ecosystems are made up of producers, consumers, and decomposers

Sustainable Air Quality
Physical displacement between producer and consumer causing additional energy to be used (ex. oil products that are shipped all over the world)
No recycling after producers--it would be pointless to produce materials and recycle them immediately without going through a consumer.
Since little or no material is passed directly from the producer to the decomposer, the material goes out into the material environment, creating an open system.How anthroposystems are different from ecosystems
I learned about the relationship between the natural system of
the earth and that system which humans have created. It is
interesting that a parallel can be drawn between the two concepts.
The environmental spheres also made me think about how everything is connected and relates to everything else. It is easy in our society to think that material just “goes away”, but this model made me think about where everything goes and how it gets there.
