This document discusses biodiversity and extinction. It defines biodiversity as the variation of life including genetic, species, and ecosystem variation within an area. Extinction is defined as the end of an organism or group of organisms, normally a species. Endangered species are those likely to become extinct. Several species in India such as the lion-tailed macaque, civet cat, and Nilgiri tahr are mentioned as examples. The document also lists several organizations that work on biodiversity conservation and defines ecological hotspots as regions with many endemic species facing threats.

4. BIODIVERSITY
Biodiversity is the degree of variation of life.

faced by the organism,they
are included as various

11. ECOLOGICAL HOTSPOT
The regions where the numbers of endemic species are large and
where the threats of ecological destruction exist are known as
Ecological hotspot.
Eg: Western ghats and eastern Himalayan regions of India
