Define the adaptation-level phenomenon

Define the adaptation-level phenomenon and provide at least one example of it. Explain how upward social comparison causes dissatisfaction and how downward social comparison facilitates contentment. In your response, provide one example that demonstrates the relationship between upward social comparison and dissatisfaction, as well as one example that demonstrates the relationship between downward social comparison and contentment.

How does each of these impact our ability to address materialism which is a major contributor to climate change?  Do you have any insight into how we can address this using other social psychology influence principles?
