Religious tourism in India has grown at an extraordinary pace in the past few years, and this surge comes with serious environmental costs. Mass pilgrimages generate vast quantities of plastic and organic waste, leading to water pollution in rivers like the Mandakini and lakes such as Pushkar, where groundwater levels have also plummeted. Deforestation from firewood collection, unchecked construction, and overuse of natural resources have caused habitat loss, soil erosion, and ecosystem disruption—particularly in ecologically sensitive areas. Local infrastructure is overwhelmed, increasing the risk of landslides, stampedes, and irreversible ecological damage. Despite its economic value, religious tourism in its current form is unsustainable—placing fragile landscapes, wildlife habitats, and water bodies under intense and often unregulated pressure.
