My diagram illustrates how the BioGas generator affects the environment and the people within it. The generator uses cow feces for methane which decreases the demand for wood which means people do not need to search for wood, decreasing the rate of deforestation. Since kids do not have to help look for wood, they do not miss school. The use of methane in replacement of wood creates less smoke in the home leading to less illness. Jobs are created in order to build the generator as well. The slurry created by the generator is mixed with fibrous materials and processed by worms which creates quality compost. This is good for the environment and creates more jobs for the people who sell the compost to farmers. Farmers have reported an increase in yield which relates back to the environment. This illustrates a human-environment system where the people’s actions affect the environment and the environment gives back to the people. The BioGas Generator could also be considered a positive feedback loop because the existence of one generator has lead to more money and jobs in order to create more generators. In Marten’s diagram he shows the relationship between two systems which are the social system and ecosystem and he includes the process of using wood for fuel. I focus on the benefits the generator gives to the environment and the people. We both show how the environment and people are connected to the generator. His diagram shows the process while my diagram adds the benefits of the process.
