Biodiversity conservation involves protecting ecosystems, habitats, and species. It aims to maintain viable populations of all native species and their genetic diversity. Key methods for biodiversity conservation include protected areas like national parks, sanctuaries, biosphere reserves, and marine protected areas. Laws like the Wildlife Protection Act (1972) and the Biological Diversity Act (2002) support conservation efforts in India. The Convention on International Trade in Endangered Species (CITES) also regulates global trade in threatened species.
