Officially, there are three extinct tiger subspecies (there is only one species, Panthera Tigris). The Caspian, Javan, and Bali. Overhunting and habitat loss doomed these tigers.
OVERHUNTING and HABITAT DEstruction took its toll on the tigers
Some species have become extinct, but others are still numerous.
There are several reasons why dozens of animal species become extinct daily. Some of these reasons include logging, and ranching. Taking away the animals habitat leaves them with no home an no source of food.
None known to have become extinct, but some stocks were depleted, and regulations had to be put in for certain species.
2015 for some species but 2020 if they are lucky.
Some or several species become extinct every day.
People try protecting tigers from harm, to keep them from extinction. Special groups preserve tigers in zoos, so that they can reproduce and have a greater population. Tigers are endangered, and there are already some extinct species.
It is hard to determine exactly how many animal species are extinct because some species become extinct before scientists even know they existed. As far as science can tell, there are over 900 extinct species.
long-lived individuals become endangered or extinct as a result of human activity.
It is hard to calculate the number of animals that have become extinct since 1681 since some species went extinct before scientists knew they existed. What is known is that more than 90 species of birds and hundreds of species of mammals have gone extinct since then.
Snakes are not extinct. Some species may be, but certainly all are not. Check Extinct Snake Species.
Estimates vary for the number of tigers in the wild today, but some say there are approximately 600 Siberian tigers left, around 2000 Bengal tigers, approximately 1200 Indochinese, just 600 Sumatran, and less than 20 South China tigers. Sadly, allsub-species are considered endangered, and three sub-species have already gone extinct.
