Unplanned tourism development can exert significant pressure on the environment, leading to various ecological challenges. As tourism burgeons without proper planning and sustainable practices, the delicate balance of ecosystems is disrupted, jeopardizing the very resources that attract visitors in the first place. This phenomenon raises concerns about the thresholds of environmental resilience and the long-term sustainability of tourism destinations.

One of the primary pressures associated with unplanned tourism development is the increased demand for infrastructure and facilities. Rapid and uncontrolled construction of hotels, resorts, roads, and other amenities can lead to habitat destruction, fragmentation, and alteration. This poses a threat to the biodiversity of the area, impacting flora and fauna, and disturbing the natural processes that support a healthy ecosystem. Fragile ecosystems, such as coastal areas, forests, and wetlands, are particularly vulnerable to this form of development.

The intensification of human activities, driven by the influx of tourists, also contributes to pollution. Improper
