This study analyzes the evolution of a region whose economy is based on marble—a natural, non-renewable resource—which has also managed to improve its protection of the environment. A development plan promoted by the local government in the 1980s made it possible to assess local extraction companies and provide them with better technology, consequently increasing the yield of reserves and the quality of the final product, while also extending the life cycle of the deposit. Furthermore, new companies began to emerge which made use of materials that had previously been discarded. Finally, investments in research were responsible for introducing new artificial composite substitutes to the market. These actions have helped to reduce product extractions and improve its sustainability.

这项研究分析了一个以大理石为基础的地区的演变，大理石是一种天然的，不可再生的资源，它还设法改善了对环境的保护。地方政府在1980年代发起的一项发展计划使评估当地的开采公司并为他们提供更好的技术成为可能，从而提高了储量的产量和最终产品的质量，同时还延长了矿床的生命周期。此外，新公司开始出现，它们使用了以前被丢弃的材料。最后，对研究的投资负责将新的人造复合材料替代品推向市场。这些行动有助于减少产品提取量并提高其可持续性。
