In this chapter, the concept of sustainability is explored using a systems thinking approach. The goal was to understand different interpretations of sustainability and how it involves more than just the environment – it includes economic and social aspects too. The research shows that sustainability is not about maintaining all practices forever; it involves making choices about what to keep and what to change. People with different views often use sustainability for political purposes, but it's not tied to any specific political agenda. The term sustainability is crucial for managing resources and has influenced economic development since a notable report in 1987.
