📖 Reading Passage

The concept of 'circular economy' has gained significant traction in recent years as a sustainable alternative to the traditional linear model of 'take-make-dispose'. Unlike linear systems, which prioritize throughput and often externalize environmental costs, a circular economy emphasizes the continuous use of resources through practices such as recycling, remanufacturing, and product-life extension. Proponents argue that this shift not only reduces waste and resource depletion but also fosters innovation in design and business models. However, critics point out that the transition is fraught with challenges, including technological limitations in material recovery, economic barriers to scaling up, and the rebound effect, where efficiency gains lead to increased consumption. Furthermore, the global nature of supply chains complicates the implementation of circular principles, as waste is often exported to developing nations with less stringent regulations. Thus, while the circular economy offers a promising vision, its realization requires systemic changes in policy, infrastructure, and consumer behavior.
