My diagram is focused very much on the sustainability of an environment and how closely coupled the environment and human interaction is with it. When looking at my diagram you can see that the Biogas System is able to function based on the usage of cow feces. Then it is shown that the system from there produces Compost, gas, and clean cooking which are all differently related to the environment and being produced by a human made system. Another concept that my diagram is based off of is the idea of feedback mechanisms. The biogas mechanism is only able to sustain itself through the production of cow feces and cows are only able to maintain life while the villagers have the means to feed and care for them so this creates a positive  feedback loop because by the more feces feces being produced the more money is made and the more cows are bought to produce.

My diagram compared to Marten’s  is similar in the ideas of what is produced and the feedback system ideas but differs in the fact that he was able to separate the social system and the ecosystem into to different areas but still had them connected in major ways. Our diagrams are different because in creating the diagrams I had a specific system that I was working with while he had general concepts. This made mine a little more messy to distinguish which system each box would belong to. What can be learned from the differences is that you are able to classify clearly black and white in some cases but in others a lot of times the ideas and categories tend to be intertwined with one another.
