Positive Feedback Loop
A positive feedback loop is a process in which an initial change in a system triggers a response that amplifies or enhances that change, leading to an exponential increase in the effect. This loop continues until an external factor intervenes to stop the amplification.
Examples:
- Climate Change: As global temperatures rise, polar ice melts, reducing the Earth’s albedo (reflectivity). This leads to more solar absorption, which further increases temperatures and causes more ice to melt.
- Childbirth: During labor, the reLease of oxytocin increases contractions, which in turn stimulates more oxytocin reLease, intensifying the contractions until delivery occurs.
- Economic Growth: Increased consumer spending leads to higher business Revenues, which can result in more hiring and investment, further boosting consumer spending.
