Key concept chapter two

"Systems have inputs, flows, and outputs of matter and energy, and feedback can affect their behavior."

This concept describes the way that components in a environment work together to make a system. The inputs in the environment work together to make an output that either benefits or hurts the environment.

This concept is interesting because of the way that the system is able to change when the feedback they receive changes.


A diagram is used to illustrate the way a feed-back loop works. The diagram starts with the input and then shows the way that the throughputs can change the output into something negative or positive.
It's interesting how the diagram can change from something negative to positive.
