This document discusses biodiversity conservation. It defines biodiversity as the variety of life on Earth at genetic, species, and ecosystem levels. The main threats to biodiversity are habitat destruction, resource mismanagement, poaching, climate change, and pollution. Legislation like the Convention on Biological Diversity aims to conserve biodiversity through both in-situ conservation of species within protected areas like national parks, and ex-situ conservation outside natural habitats in botanical gardens and seed banks. India has many national parks that help protect endangered species like tigers, rhinos, snow leopards, and lions.
