What is biodiversity?
Biodiversity is the variety of all animals, plants, microorganisms, and their ecological interactions, including non-living factors like soil, air, and light.
What are some threats to biodiversity?
What are some threats to biodiversity?
Habitat destruction, fragmentation, environmental pollution, soil erosion, agricultural expansion, urbanization, deforestation, and indiscriminate hunting.

Study Notes
- Biodiversity is defined as the variety of all animals, plants, microorganisms, and the ecological complexity they interact with, including non-living factors like soil, air, and light.
- Threats to biodiversity and cases of extinction are caused by habitat destruction, fragmentation, environmental pollution, soil erosion, agricultural expansion, urbanization, deforestation, and indiscriminate hunting.
- Exotic species introduction can lead to the extinction of wild animals by causing dominant species to eliminate existing species in the area.
- Disturbances in migratory roots, such as building dams along fish migration routes, can block their path and lead to extinction.
- Lack of education about wildlife and its importance can lead to people not understanding the significance of conserving wildlife and ecosystems.
- Conservation of biodiversity can be done through Insitu conservation (protecting wildlife in their natural habitat) and Exsitu conservation (protecting wildlife in man-made environments).
- Insitu conservation includes Sacred forests, Sacred lakes, Biosphere reserves, National parks, and Wildlife sanctuaries that protect wildlife based on specific activities allowed in different zones.
- India has 18 Biosphere reserves, 106 National parks, and 567 Wildlife sanctuaries.
- Biosphere reserves are specific areas divided into three zones: Core Zone (no human activities allowed), Buffer Zone (limited human activities allowed), and Manipulative Zone (multiple human activities allowed).
- Exsitu conservation involves activities like Botanical gardens, Zoos, Gene banks, Tissue culture, Pollen culture, DNA banks, Cryo-preservation to protect wildlife in man-made environments.
- Cryo-preservation involves storing DNA or tissue samples in liquid nitrogen at -196 degrees Celsius to prevent any fungal, viral, or bacterial activity.
