Select the correct statement about biodiversity.
A
Conservation of biodiversity is just a fad pursued by the developed countries
B
The desert areas of Rajasthan and Gujarat have a very high level of desert animal species as well as numerous rare animals
C
Large scale planting of Bt cotton has no adverse effect on biodiversity
D
Western Ghats have a very high degree of species richness and endemism
Detailed Solution
Biodiversity hotspots are regions with very high levels of species richness and a high degree of endemism (species confined to that region and found nowhere else).
The Western Ghats and Sri Lanka, Indo-Burma and the Himalaya are hotspots that cover India's exceptionally high biodiversity regions.
So the statement about the Western Ghats is correct.
Conservation of biodiversity is a necessity for all countries for narrowly utilitarian, broadly utilitarian and ethical reasons; it is not a fad.
Desert areas have low species richness compared with tropical forests, and large-scale monoculture of a single crop variety such as Bt cotton reduces genetic diversity.
Hence the correct statement is that the Western Ghats have a very high degree of species richness and endemism.
