The diagram explains the benefits of the Biogas Generator, both for the ecosystem and the social system. It shows the Human-Environment System in a visual form. The society explained in the video used firewood as their main source of fuel for cooking. Burning firewood increased pollution and also increased deforestation. The diagram above shows how the Biogas Generator removed burning firewood by using cow dung to produce methane gas which fueled the generator. Burning methane gas creates much less pollution than burning firewood does. The decrease in the use firewood slows down the deforestation in the area which impacts the ecosystem drastically. The generator also produces compost. People then sold the produced compost which increased their incomes and also created more jobs for compost sellers.

My diagram and the diagram given by Gerald Martin have many similarities and differences. For one thing, both of our diagrams show how the Biogas Generator affects the Human-Environment System in the Indian society. A difference between our diagrams is that he included how the generator affects farm fields. My diagram leaned more toward pollution and how the generator reduced it while his diagram leaned more toward the population aspect of the system. There are similarities because there are many ways to look at the situation and not one of them is more correct than the other. Whether you look at my diagram or Martin’s, you will still get information on how the Biogas Generator affects the Human-Environment System.
