Mass tourism refers to the large-scale movement of people to popular destinations, often resulting in overcrowding and environmental strain. This phenomenon typically occurs in well-known locations such as Paris, Rome, or Cancun, where many travelers visit simultaneously, especially during peak seasons. The impact of mass tourism can be both positive and negative. On one hand, it boosts local economies by creating jobs and generating revenue. On the other hand, it can lead to issues like pollution, cultural erosion, and the degradation of natural resources, making sustainable tourism practices increasingly important.
