Wildlife sanctuaries play a crucial role in ecological conservation by providing protected areas for endangered and threatened species. These sanctuaries offer safe habitats where wildlife can thrive without the pressures of urban development and poaching. They also serve as vital zones for research and education, promoting awareness about biodiversity and conservation challenges. Additionally, wildlife sanctuaries contribute to ecological tourism, which can generate funding for conservation efforts. Overall, they are integral to preserving biodiversity and maintaining essential ecosystem functions.
