What happens when the places we travel to for their beauty, history, and culture begin to crumble under the weight of our visits? How do we know when tourism, once a source of pride and income, begins to cross the line into exploitation? In this discussion, we’ll focus on Venice, a city that has become a global symbol of overtourism, where cruise ships tower over centuries-old canals, and residents are increasingly pushed out by short-term rentals and crowds. But Venice is just one example of a growing global issue: heritage cities around the world are struggling to preserve their identity, livability, and cultural significance under intense tourist pressure._x000D_ _x000D_ We’ll explore what defines a heritage city, the warning signs of unsustainable tourism, and the difficult balance between welcoming visitors and protecting cultural treasures. From urban policies and preservation strategies to grassroots resistance and international cooperation, we’ll look at the facts and ask what can be done. And while Venice is a headline case, we’ll also consider heritage cities in China, how they’re being affected, and what might still be done to safeguard their future. Let's have a smart, fact-based conversation about the impact of tourism on places that matter most._x000D_ _x000D_ 当我们为了美丽、历史和文化而旅行的地方，开始因我们游客的涌入而崩塌时，究竟发生了什么？我们如何知道，曾经是骄傲与收入来源的旅游，何时开始跨越了剥削的界限？在这次讨论中，我们将聚焦威尼斯这座城市，它已成为过度旅游的全球象征，巨型游轮高耸在几百年历史的运河上，居民们越来越被短租和人流挤出。但是，威尼斯只是全球越来越严重问题的一个缩影：世界各地的文化遗产城市都在承受着巨大的游客压力，努力维持它们的身份、宜居性和文化意义。_x000D_ _x000D_ 我们将探讨什么定义了文化遗产城市，如何识别不可持续旅游的警示信号，以及如何在欢迎游客与保护文化宝藏之间找到艰难的平衡。从城市政策和保护战略，到草根抗议和国际合作，我们将分析事实，并探讨可以采取的措施。虽然威尼斯是一个典型案例，我们也将讨论中国的文化遗产城市，它们正面临的影响，以及如何保护它们的未来。让我们一起进行一次聪明、基于事实的对话，探讨旅游对那些最重要地方的影响。
