For my diagram, I thought of the negative effects of collecting firewood and dung had, then the positive changes biogas generators would bring to those rural areas. This topic strongly correlates with the coupled human – environment systems topic we learned in the module. With the use of biogas, there are several positive outcomes. Using firewood for cooking fuel has several downfalls: deforestation of the environment, and added pollution and greenhouse gases in the air. Using biogas generators allows for waste to be used as fuel, saving time for children to go to school and do schoolwork. In addition, the women in the community reported increased income with business opportunities. The connection between the social system and the ecosystem is undeniable, because all of the changes brought about with the biogas generator directly affect the way the ecosystem’s state. The main difference between my diagram and Marten’s diagram is that Marten’s has several more correlations between components. I leave my diagram as it is for the sake of simplicity, because the more you look at the involved components the more connections one can make between them all.
