What is the difference between a national park and a wildlife sanctuary?

The difference between a national park and a wildlife sanctuary lies in the level of protection and human activity allowed within them. A national park is a highly protected area where no human activities such as grazing, hunting, or resource extraction are permitted, and the primary objective is the strict conservation of ecosystems and biodiversity. In contrast, a wildlife sanctuary allows limited human activities like grazing, collection of minor forest products, and regulated tourism, provided they do not harm wildlife. National parks have stricter legal boundaries and conservation rules, whereas wildlife sanctuaries offer more flexible management while still focusing on the protection of animals and their habitats.
