What are national parks, wildlife sanctuaries, and biosphere reserves?

National parks, wildlife sanctuaries, and biosphere reserves are protected areas established to conserve biodiversity and natural ecosystems. National parks are strictly protected areas where human activities such as hunting, grazing, and resource extraction are not allowed, ensuring complete protection of flora, fauna, and their habitats. Wildlife sanctuaries provide protection to animals but allow limited human activities like grazing or tourism under regulation. Biosphere reserves are large areas that include core, buffer, and transition zones, aiming to conserve biodiversity while promoting sustainable development and research activities. These conservation areas play a vital role in protecting endangered species, maintaining ecological balance, and supporting environmental sustainability.
