The purpose of this diagram was to demonstrate the coupled Human-Environment system in India that was discussed in the video using biogas for fuel. In order to understand this, a systems perspective is being utilized, having the ecosystem and the social system as two different entities that are able to interact with each other. In my diagram, I decided to started with Cow and animal wastes as this is where the biogas technology starts. From here I moved toward the social systems and how the biogas generators are able to snowball into almost every social aspect in the communities.The environment is allowed to thrive as less trees are used as well as cleaner air since methane burns more efficiently.

Comparing my diagram to Figure 1.5 in “What is Human Ecology?”, there are some similarities. One thing that was both included was that animal dung was the main source of fuel for the biogas generators, and that some of the byproducts could be used for farming as fertilizer. Some differences in my diagram is that I did not include trees and shrubs on hills, as well as cutting wood. I opted to focus on the biogas technology and its benefits rather than the fuel used from wood. There are similiarties and differences because both cover the new technology and its overall effect in different parts of the community. It can be learned that this new technology in India may not always be avialable adn that deforestation still occurs because of this.
