One of the core ideas in regards to my diagram is the effect that cow dung has on both the environment, education, and workforce of India. The human-environment system clearly shows that while humans impact the environment, the environment affects humans as well. For example, due to the use of cooking gas, this impact led to itching of the eyes, as well as cough/chest health issues. When children and females in India were collecting sticks for the use of cooking, this impact led to the decrease of trees; an overall unhappier environment due to our impacts upon each other. Once positive changes were made, for example, cow dung mix; the use of less gas and sticks caused an overall increase in the health of the humans and a cleaner environment. The use of the sticks and gas was a disturbance to both the humans and the environment, but the resilience, our ability to recover after this disturbance, led to positive changes such as increase in the workforce, education, and health. In comparison in the Marten reading “What is Human Ecology?”, both our diagrams have the two main components of social system and ecosystem. Our idea of using two-direction arrows indicates that the Marten diagram and mine both have the same general idea of the human-environment system and how they both impact each other. This is a similarity that can be learned by realizing this is a system diagram that is consisted of several components that interact, and affect each other; a systems perspective. In contrast, Figure 1.5 focuses more on the possible future benefits that biogas has towards villages, while my diagram is based upon benefits that already occurred to the villages because of the positive changes. His introduction to these benefits could lead to unknown thoughts and discussion that maybe wasn’t possibly thought about.
