Over the last 100 years, almost 96% of the tiger population across the globe has been wiped out. According to the World Wildlife Fund, there are only approximately 3,900 wild tigers left in the world. But, there is still hope to revive their population and you could be a part of the change. Several organisations such as the David Shepherd Wildlife Foundation and zoos in Delhi and Kolkata allow you to 'adopt a tiger'. This way you can fund protection programmes and campaigns run by these organisations. The major threats to their population come from poaching, loss of habitat and human-tiger conflicts. By adopting a tiger, you could help conduct camera trap surveys to guide further action, restore the already fragmented areas of their habitat and strengthen anti-poaching policies that exist in these protected areas.
