Critically endangered tigers.  See a decent clip about Sydney's Toronga Zoo. See a new tiger experience there.  You will take a simulated flight and live life-on-the-edge in beautiful Sumatra (Indonesia).  Meet real Sumatran tigers in the jungle.  Walk in a local village and market stall.

 The jungle is vital habitat for endangered tigers, orangutans, elephants and more and regulates green house gases.
 In Indonesia, prolonged wildfires and smoke pollution on a vast scale have happened, the soil, the timber and rivers all need protection and policing as well as maintaining a healthy natural environment for the people and the visitors to enjoy.  Just as we need to do the same in our own 'backyard'.
