Let’s Begin…

While feedback loops are a bummer at band practice, they are essential in nature. What does nature’s feedback look like, and how does it build the resilience of our world? Anje-Margriet Neutel describes some common positive and negative feedback loops, examining how an ecosystem’s many loops come together to make its ‘trademark sound.’

The process of erosion on a landscape is an example of positive feedback. Can you describe a feedback loop that explains this process in more detail, starting with the feedback between plant, humus, and at least one more node in the network? Hint: you will have to add more than one negative link.
