Define bio-diversity and explain major threats to biodiversity.
In short
Biodiversity is the variety and variability of life at genetic, species and ecosystem levels, and India, with only 2.4% of the world's land, holds about 8% of recorded species. The major threats are habitat loss and fragmentation, overexploitation, invasive species, pollution, climate change and weak governance.

Comprehensive Scope
Biodiversity spans genetic diversity, species richness, and ecosystem variety, with India’s 10 bio-geographic zones, including the Western Ghats and Himalayas, rich in endemic species that contribute to ecological stability.
India’s Richness and Importance
Despite covering only 2.4%1 of the world’s land area, India harbours 8% of global species, including over 96,000 animals and 47,000 plants; Telangana’s ecosystems are key biodiversity reservoirs requiring focused conservation to maintain ecological functions and genetic resources.
Habitat Loss and Fragmentation
Deforestation, urbanisation, and agriculture fragment habitats, leading to species decline; Mission Kakatiya in Telangana exemplifies restoration efforts to protect wetlands and species by reviving water bodies critical for biodiversity.
Governance and Socioeconomic Pressures
Weak enforcement of environmental laws and funding cuts in flagship projects like Project Tiger exacerbate biodiversity loss; poverty-driven resource exploitation further stresses ecosystems.
Restoration and Enforcement
Expand projects like Mission Kakatiya to restore habitats, increase conservation funding, and strengthen enforcement of wildlife protection2 laws to curb poaching and illegal trade.
Community Involvement and Control Measures
Empower Biodiversity Management Committees3 and People’s Biodiversity Registers to integrate traditional knowledge; develop rapid response systems to control invasive species and promote sustainable resource use.
