Tigers are one of the most powerful and graceful animals in the world. The different species that still exist today, namely the Bengal, Indochina, Siberian, South China and Sumatra tigers are in danger of becoming extinct. Due to irresponsible hunting, the Bali, Caspian and Java tigers have already become extinct. This could soon happen to the other species too. In the past, tigers were considered as pests. With a smaller area to hunt, as man had taken up more of the land to build upon, the tigers found less area for themselves to hunt. They thus turned to farms to get their food. Farmers’ livestock were attacked by these tigers. People were then encouraged to hunt and kill these animals with the promise of rewards. Even after the threat of tigers on livestock was over, man continued to hunt tigers, this time for recreation. Poachers too hunt tigers for their body parts knowing that the skin of tigers is much sought after. Bones and other organs are also used as ingredients in traditional Chinese medicine. Although killing is illegal, it is still being carried out unless it is stopped, the remaining species of tigers will soon become extinct too. 24. How many species of tigers were there originally?
