Why large numbers of tourists can cause problems at popular tourists sites?

Large numbers of tourists can lead to overcrowding, which often strains local infrastructure and resources, such as transportation, waste management, and public facilities. This influx can also damage natural environments and historical sites, as increased foot traffic can erode pathways and contribute to pollution. Additionally, the local culture may be disrupted, as residents may feel overwhelmed or marginalized by the tourist presence. Ultimately, these factors can diminish the overall experience for both tourists and locals.
