The main point of this diagram is the sustaining of a community and environment. The biogas plant not only adds positive elements into the community, but also removes some harms from the community and the environment. It adds both economic and environmental stability into the community by providing buying power to poor families through the production of compost for sale and the lessening of deforestation and influx of compost improve the environment around the community.
My diagram and the diagram produced by Gery Marten are similar in they both contain human and environmental components. Both of our diagrams, also, take into account humanity’s effect on the environment. The difference between our two diagrams is that Marten separates the social and environmental systems, while my diagram they are more mixed together. His diagram takes into account the interactions inside those two systems, more than the interactions between the two systems. The interactions he has between the two are generalized to: energy, materials, and information, and are specified as either human activities or ecosystem services. These differences tell us that two kinds of system diagrams can exist. Information about the interaction between the social and environmental systems can be seen in diagrams like mine, while interactions in those two systems can be shown in diagrams like Marten’s. Each are important when looking at how different components in a community are affecting one another to possibly understand exactly what is happening and fixing any problems in the system.
