📖 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 continual use of resources through recycling, remanufacturing, and sharing platforms. Proponents argue that such a shift not only reduces waste and resource depletion but also fosters innovation and economic resilience. However, critics point to practical barriers, including the high upfront costs of redesigning products for durability and the complexity of global supply chains, which can undermine the feasibility of fully closed-loop systems. Nevertheless, incremental adoption in sectors like electronics and fashion suggests that circular principles can be integrated without complete systemic overhaul, offering a pragmatic pathway toward sustainability.
