According to the data tabled in the Lok Sabha by the Ministry of Environment, Forest and Climate Change,4 species of fauna and 18 species of flora have gone extinct in India in the past few centuries.
The data has shown that among mammals,the following are considered extinct in India (a)Cheetah(Acinonyx jubatus) (b)Sumatran rhinoceros (Dicerorhinus sumatrensis) (c)Pink-headed duck (Rhodonessa caryophyllacea) and (d)Himalayan quail (Ophrysia superciliosa).
The factors like competition, predation, natural selection and human induced factors like hunting, habitat degradation are some of the important reasons that have led to these extinction.
