3. Biodiversity is the degree of variation of life forms within a given species,
ecosystem, biome, or an entire planet. Biodiversity is a measure of the
health of ecosystems. Biodiversity is in part a function of climate.
4. The period since the emergence of humans has displayed an ongoing
biodiversity reduction and an accompanying loss of genetic diversity.
Named the Holocene extinction, the reduction is caused primarily by
human impacts, particularly habitat destruction. Conversely, biodiversity
impacts human health in a number of ways, both positively and
5. The sacred groves of India are some of the areas in the country where the richness
of biodiversity has been well preserved. The Thar desert and the Himalayas are two
regions rich in biodiversity in India. There are 89 national parks and 504 wildlife
sanctuaries in the country, the Chilika Lake being one of them. This lake is also an
important wetland area. Learn more through map on biodiversity in India.
6. The term biological diversity was used first by wildlife scientist and conservationist
Raymond F. Dasmann in the 1968 lay book A Different Kind of Country advocating
conservation. The term was widely adopted only after more than a decade, when in
the 1980s it came into common usage in science and environmental policy.
Thomas Lovejoy, in the foreword to the book Conservation Biology, introduced the
term to the scientific community.
7. Biodiversity is not evenly distributed, rather it varies greatly across the globe as
well as within regions. Among other factors, the diversity of all living things (
biota) depends on temperature, precipitation, altitude, soils, geography and the
presence of other species. The study of the spatial distribution of organisms,
species, and ecosystems, is the science of biogeography.

9. Conservation biology matured in the mid-20th century as ecologists, naturalists, and other
scientists began to research and address issues pertaining to global biodiversity declines.
The conservation ethic advocates management of natural resources for the purpose of
sustaining biodiversity in species, ecosystems, the evolutionary process, and human culture and
society.
Conservation biology is reforming around strategic plans to protect biodiversity.

12. To prevent such loss, the Government of India is setting up biosphere reserves in different parts
of the country. These are multipurpose protected areas to preserve the genetic diversity in
different ecosystems. Till 1999, ten biosphere reserves had been set up, namely Nilgiri,
Nandadevi, Nakrek, Great Nicobar, Gulf of Mannar, Manas, Sunderbans, Similipal, and Dibru
Saikhowa. A number of NGOs are being involved in the programme to create awareness. But
legal protection is provided only to national parks and sanctuaries, which cover about 4.5% of
India’s land area.
