Human being’s Demand and Supply Chain

You might have seen food chain, but have you seen human being’s demand and supply chain? Here is an attempt in this regard.

Upon careful observation of this picture (and where the arrow marks are present and not present), complex relationship between various entities will unfold.

Using this, we can easily explain several things that we read-hear everyday, especially to kids. For ex: How environment will be harmed by population increase? What role does energy play in our lives? etc.

Overall, I believe this can be pretty useful during research or illustration of the effects of increase or decrease of one entity (including human population) on each other and in general human life.
