Here are some ways to deal with this crisis:

learn as much about tigers as you can, and teach others about the threats they face.

Raise money for a tiger conservation organization – on your own, or as a school or scout-group project.

don`t buy tiger products like tiger fur or teeth because people kill tigers to sell these products.

Protect forests

Stop poaching and don't encourage poachers

Force governments to enact severe punishment for poachers

Reduce pressure on natural resources

One more thing to help saving tiger population is to travel tiger reserves that are large plots of the tigers’ native land that has been specifically designated for the tigers. Of course, visiting a tiger reserve means flying to places like India or Nepal. If you have the ability to do so, then while you are there you should join a tour operated by the park service of the country. They rely on the income from tourism to help pay for part of their expenses. Tourism also brings money to the area where the reserve is located, which in turn inspires support for the reserve from the local community.

Do some research on the tour company before you fly off to visit the tiger reserve or national park.
