Record numbers of visitors are flooding Yosemite National Park this summer, coinciding with the United States' 250th anniversary celebrations. The surge in tourism is reviving conservation debates that date back to the mid-19th century.

Historically, Yosemite has faced challenges balancing public access with environmental preservation. Increased foot traffic can lead to erosion and habitat disruption, threatening the park's delicate ecosystems.

The influx of visitors also strains local infrastructure and services, potentially leading to long-term socio-economic impacts on nearby communities that rely heavily on tourism.
