World Wildlife Day: Cheetahs, which once roamed across much of India and West Asia, are now confined to just a few dozen animals in remote regions of Iran. The big cat was declared extinct in India over 70 years ago. The world's fastest land mammal is considered vulnerable under the International Union for Conservation of Nature (IUCN)'s red list of threatened species, with a declining population of less than 7,000 found primarily in African savannas. However, on Wednesday, Union Environment Minister Prakash Javadekar said the government was working on re-introduction of Cheetah. This big cat will be a reality soon, he tweeted on World Wildlife Day.
